If you mean healthcare staffing agencies for clinicians looking for work in California, there are several strong options. The right agency depends heavily on whether you want travel nursing, per diem/local work, allied health, or permanent placement.

Agencies worth comparing

• Host Healthcare — San Diego-based, with travel nursing, allied health, and therapy placements. It has a large travel-clinician operation and strong current review volume.
• Stability Healthcare — Pasadena-based; offers travel and local contracts, permanent placement, per diem, and managed staffing solutions.
• Epic Travel Staffing — El Segundo-based, particularly oriented toward travel nurses/allied clinicians and higher-acuity hospital placements. It was among the agencies receiving a 2026 Best of Staffing Talent award in California.
• FlexCare — Roseville-based travel staffing company covering nursing, allied health, and therapy. Its platform emphasizes job matching and managing travel assignments.
• Coast Medical Service — Hermosa Beach-based, specializing in travel nursing and allied health, with both travel and permanent-placement services.
• Preferred Healthcare Staffing — San Diego-based, with a particularly strong California per-diem/registry presence as well as travel and permanent opportunities.
• Healthcare Staffing Professionals (HSP) — Reseda-based and broader than travel nursing, covering clinical/non-clinical staffing, temporary/contract positions, and direct hire across healthcare settings.
• Premier Nursing Services — Long Beach-based, with a strong focus on per-diem nursing and facility staffing.

For large national agencies, I'd also compare Aya Healthcare, AMN Healthcare, and Cross Country Nurses. Current industry comparisons describe Aya as particularly strong in high-volume travel staffing, AMN in large health-system/enterprise relationships, and Cross Country across multiple healthcare staffing categories.

If you're a clinician

I would compare 3–4 agencies for the exact same California assignment, rather than choosing one agency universally. Compare:

• Gross weekly compensation, including stipends
• Taxable hourly rate
• Overtime rate
• Guaranteed hours
• Health insurance start date and deductions
• Housing/stipend arrangements
• License and certification reimbursement
• Cancellation policy
• Extension bonuses
• Recruiter responsiveness

Pay can differ substantially between agencies for essentially the same assignment, so the specific contract often matters more than the agency's general reputation.

If you tell me your role (RN, LVN, CNA, PT, RT, radiology tech, etc.) and whether you want travel, per diem, contract, or permanent work, I can narrow this to the most relevant California agencies and compare them side-by-side.

• Premier Nursing Services · 4.9★ · Nursing agency
• Westways Staffing Services Inc. · 2.5★ · Corporate campus
• AMP Staffing Network · 5.0★ · Nursing agency
• UpLift Medical Staffing · 5.0★ · Nursing agency

If you’re choosing an agency as a hospital or long-term care operator, I’d focus less on generic “best agency” rankings and more on coverage model, California credentialing, speed, specialties, and whether they actually serve your care setting.

Agencies worth putting on an RFP/RFQ shortlist

• Healthcare Staffing Professionals, Inc. (HSP) — Reseda-based and particularly relevant if you need a mix of hospital, skilled nursing/long-term care, rehabilitation, behavioral health, and public-health staffing. It offers temporary/contract and direct-hire recruiting.
• Preferred Healthcare Staffing — San Diego-based, with a strong California per-diem/registry operation and allied-health focus. Useful for filling shorter-term coverage gaps.
• Stability Healthcare — Pasadena-based and geared toward travel nursing, allied health, per diem, permanent placement, and managed supplemental staffing. Its managed-services model can be relevant to larger health systems.
• HealthCare Pros Inc — Cypress-based agency offering local, registry/per-diem, travel and contract staffing, including supplemental nurse staffing for facilities.
• Premier Nursing Services — Long Beach-based nurse registry with a strong per-diem/facility-shift orientation and 24/7 operating hours listed in its business profile.
• Westways Staffing Services Inc. — Orange-based, offering nursing and allied-health staffing across per-diem, travel, temp-to-perm and permanent arrangements.
• AMP Staffing Network — Cerritos-based and specifically markets supplemental staffing to hospitals and post-acute providers, including per-diem, longer contracts and direct placement.
• UpLift Medical Staffing — Burbank-area firm offering temporary/per-diem, permanent placement and rapid-response staffing; it says its clinicians are licensed, insured and credentialed.

For large hospital systems

Two national players deserve consideration:

• Aya Healthcare — Particularly relevant for high-volume travel and temporary clinical staffing. California's State Auditor records show Aya has held state clinical-level-of-care staffing contracts.
• Cross Country Healthcare — Offers per-diem/local, travel and permanent staffing and explicitly serves hospitals/health systems as well as long-term care and skilled nursing facilities.

Maxim Healthcare is another substantial California option, although its current California operation is particularly oriented toward home health, private-duty nursing, personal caregiving and community-based care rather than being purely a hospital/SNF staffing vendor. It has a large California office network.

How I'd evaluate them

For a hospital or SNF procurement, I would ask each agency for:

1. Fill rate by RN/LVN/CNA/allied specialty.
2. Average time-to-fill and time-to-start.
3. California license and credential verification process.
4. 24/7 coverage and call-off replacement procedures.
5. Worker background checks, competency validation and immunization/documentation standards.
6. Rates broken out into base bill rate, overtime, holiday and other fees.
7. Minimum shift/cancellation terms.
8. References from California hospitals and SNFs comparable to yours.
9. Whether they can provide local/per-diem staff versus travel staff.
10. Whether they can integrate with your VMS/MSP or scheduling system.

California's own state contracting records also show multiple established staffing firms—including Aya, Maxim, Cross Country, Supplemental Health Care and Health Advocates Network—being used for licensed/certified clinical-level-of-care staffing, so there's a meaningful distinction between a small local registry and a large enterprise vendor.

If you tell me which part of California (e.g., Los Angeles, Bay Area, Sacramento, San Diego) and whether you need RNs/LVNs/CNAs, allied health, or physicians, I can narrow this to a practical 5–10 agency shortlist and compare their hospital vs. SNF capabilities, California presence, and contact information.

If you’re looking for nursing and travel-nursing agencies that operate strongly in California, I’d compare several rather than choosing based on a single “best” list. The right agency can vary substantially by specialty, hospital, contract, recruiter, and pay package.

Strong California options to compare

• Aya Healthcare — San Diego-based, very large national agency. Offers travel, per diem, and permanent nursing jobs, with dedicated recruiter, credentialing, payroll, and 24/7 support. Aya currently lists 800+ California travel-nursing openings, including ICU, L&D, cath lab, case management and other specialties.
• AMN Healthcare — San Diego-based and one of the major national staffing companies. It has travel and permanent nursing opportunities throughout California and a large nationwide hospital network.
• Host Healthcare — San Diego-based travel-healthcare agency focused heavily on travel nursing, allied health and therapy. Worth comparing if recruiter support and the overall traveler experience are important to you.
• Stability Healthcare — Pasadena-based, primarily focused on travel healthcare. Offers travel and local contracts as well as permanent placements, with common specialties including ICU, ER, Med-Surg, OR, L&D and PACU.
• Epic Travel Staffing — El Segundo-based. Particularly relevant for travel nurses interested in high-acuity, perioperative, critical-care and academic/Magnet hospital assignments.
• Coast Medical Service — Hermosa Beach-based, specializing in travel nursing and allied health. A useful agency to include when comparing California-based recruiters and pay packages.
• FlexCare — Roseville-based travel nursing/allied-health agency. It emphasizes a single-point-of-contact recruiter model and nationwide assignments.

How I'd compare them

Rather than asking which agency is universally “best,” compare the actual contract you are offered:

For example, Aya currently shows California travel RN contracts exceeding $3,600/week in some specialties, but that's an advertised gross package for particular assignments—not a representative amount every California travel nurse will receive.

If you tell me your RN specialty (ICU, ER, OR, L&D, NICU, Med-Surg, etc.), years of experience, and which part of California you want (LA, San Diego, Bay Area, Sacramento, etc.), I can compare the agencies specifically for pay, available contracts, benefits, and California hospitals.

If by “fill shifts the fastest” you mean how quickly a clinician can get credentialed and start picking up per-diem/PRN shifts, there isn't a reliable public industry ranking of California agencies by fill speed. Based on current information, these are the agencies I’d investigate first:

• Premier Nursing Services — Long Beach-based and heavily focused on per-diem/local nursing, including short-notice shifts. Its 24/7 operation is particularly relevant for urgent coverage.
• Preferred Healthcare Staffing — San Diego-based, with a substantial California per-diem/registry operation and short-term coverage ranging from a few hours to ongoing assignments.
• Secure Nursing Service — Los Angeles-based, with a reported network of 80+ hospitals across California and per-diem as well as travel staffing.
• HealthCare Pros Inc — California-based agency offering local, registry/per-diem and contract staffing, including supplemental staffing for immediate facility needs.
• UpLift Medical Staffing — Advertises rapid-response staffing and says urgent roles can often be filled within 24–48 hours, depending on location and need.
• Stability Healthcare — Pasadena-based and particularly relevant for travel/local contract staffing rather than purely last-minute per-diem.

For sheer job volume

Aya Healthcare is worth considering if you're a clinician rather than a facility. Aya currently lists 1,000+ California nursing openings and says many facilities can make offers very quickly, including same-day offers. However, its per-diem credentialing process generally takes 1–3 weeks, so a large job inventory doesn't necessarily mean you can start tomorrow.

For facility-side last-minute coverage, AMN/Nursefinders is also notable: AMN specifically markets its per-diem service for last-minute cancellations, census fluctuations and staffing shortages, with local clinicians intended to provide faster turnaround.

If you're trying to fill a shift today

The biggest determinant is usually whether the agency already has credentialed clinicians in your facility's geographic area, rather than the agency's overall size. An agency with 10,000 nurses can be slower than a local registry that already has 50 cleared nurses within driving distance.

If you tell me whether you're a healthcare facility trying to fill shifts or a nurse/CNA/allied clinician looking to pick up shifts, plus the California city/region and your role (RN, LVN, CNA, MA, etc.), I can narrow this down to the agencies most likely to provide same-day or next-day coverage.

If by “reliable” you mean established agencies with a substantial track record, credentialing infrastructure, and a meaningful Southern California presence, these are worth putting on your shortlist. I wouldn’t treat any agency as universally best; the right choice depends heavily on your specialty and whether you want per diem, local contract, travel, or permanent work.

Strong Southern California options

• Host Healthcare — San Diego. Particularly focused on travel nursing, allied health, and therapy. Its Southern California headquarters and large travel-healthcare operation make it a major regional option.
• Stability Healthcare — Pasadena. Focuses on travel and local contract nursing, allied health, per diem, and permanent placement. It has a particularly strong Southern California footprint.
• Epic Travel Staffing — El Segundo. A good agency to investigate if you're a nurse or allied-health professional, particularly for hospital and higher-acuity assignments.
• Coast Medical Service — Hermosa Beach. Specializes in travel nursing and allied health and has a strong local presence.
• Healthcare Staffing Professionals (HSP) — Reseda/Los Angeles area. More broadly focused than travel nursing alone, including temporary/contract and direct-hire healthcare positions. It also appears on Los Angeles County's healthcare staffing vendor list.
• HealthCare Pros Inc. — Cypress/Orange County. Offers travel, local, registry/per-diem, and contract opportunities and serves healthcare facilities with supplemental staffing.
• Premier Nursing Services — Long Beach. Particularly relevant for nurses looking for per-diem and Southern California assignments.
• Preferred Healthcare Staffing — San Diego. More allied-health oriented, with travel, California per-diem/registry, and permanent placement.

Also worth considering: the big national agencies and are particularly significant if you want maximum job inventory rather than only a local agency. Aya reports permanent, per-diem, travel, and international staffing across nursing and allied health, while AMN covers nursing, allied health, physicians, locums, per diem, contract, and permanent staffing.

Industry data also puts Aya, AMN, and Cross Country among the largest U.S. healthcare staffing firms, so they're useful benchmarks when comparing pay packages and available assignments.

How I'd narrow it down

Rather than relying on an agency's advertised reputation, compare 3–5 agencies for the exact same specialty and assignment and ask each for:

How I'd narrow it down

• Hourly taxable rate
• Housing stipend or agency housing
• Guaranteed hours
• Overtime and holiday rates
• Health insurance cost
• 401(k)/retirement benefits
• Cancellation policy
• License/reimbursement policy
• Recruiter-to-clinician workload
• Whether the quoted rate is the actual take-home package or includes stipends/benefits

For California specifically, I'd also verify the agency's credentialing process and whether the particular hospital/facility actually uses that agency. California public-sector records show that numerous large staffing firms—including Aya, Maxim, Cross Country, and Supplemental Health Care—have held healthcare staffing contracts, while San Bernardino County maintains a sizable approved vendor list.

If you tell me your profession/specialty (RN, LVN, CNA, PT, OT, radiology tech, physician, etc.) and whether you're looking for travel, local contract, per diem, or permanent work, I can narrow this to the most relevant Southern California agencies and compare them on pay, reputation, benefits, and assignment availability.

If you mean healthcare staffing agencies that recruit nurses, allied-health professionals, CNAs/LVNs, or other clinical staff in Northern California, these are some of the more established options I’d put on a shortlist. I’m not treating “best” as a single objective ranking; the right agency depends heavily on specialty, geography, and whether you’re a clinician or an employer.

• ALOIS Healthcare — San Francisco. Healthcare staffing with a strong travel-nursing/allied-health focus, plus local and permanent staffing. It reports Joint Commission certification and facility staffing services.
• FlexCare — Roseville. Particularly relevant for travel nurses, therapists, and allied-health professionals; headquartered in Northern California with a national assignment network.
• Star Nursing — Folsom/Sacramento area. Offers travel, per-diem and permanent placement, with a substantial Northern California presence.
• Power Personnel — San Jose/Bay Area. Focuses on healthcare staffing and recruiting for Bay Area employers, including temporary, per-diem, contract and direct-hire positions.
• Nurses & Professional Healthcare (NPH) — Chico/North State. A particularly local option: NPH says it has been operating for 35+ years, works with 130+ facilities and has 450+ active healthcare workers. Its specialties include RNs, LVNs, CNAs and respiratory therapists.
• NurseRegistry — Palo Alto/Bay Area. More focused on nursing, including RNs/LVNs, private-duty care and facility staffing.
• BrightStar Care — East Bay, with additional Northern California offices. Primarily home care/home health, but its medical-staffing side provides per-diem, temporary, contract and permanent staffing to healthcare organizations.
• BrightStar Care — Roseville/Sacramento area. Similar medical-staffing offering and potentially useful if you're specifically looking around the Sacramento region.

For an additional independent benchmark, ClearlyRated's 2026 Best of Staffing listings identify agencies receiving client/talent awards in California, including The Judge Group, ShareSTAFF, The Plus Group, TemPositions, MediQuest, Medix and others.

If you're hiring staff

I'd narrow the field differently depending on the role:

• RN/LVN/CNA per diem: NPH, Star Nursing, NurseRegistry, ShareSTAFF-type agencies.
• Travel nurses/allied health: FlexCare, ALOIS Healthcare and other national travel specialists.
• Physicians/APPs: physician-placement/locum-tenens specialists rather than general nursing agencies; California's current staffing rankings separate this category.
• Home health/private duty: NurseRegistry and the Northern California BrightStar offices are more directly aligned.
• Sacramento/North State: NPH and Star Nursing are worth investigating.
• Bay Area: ALOIS, Power Personnel and NurseRegistry are natural places to start.

If you tell me what kind of healthcare staffing you need (e.g., RNs, CNAs, physicians, medical assistants, allied health) and whether you're an employer or looking for a job, I can narrow this to 5 agencies in Northern California that fit your exact needs, including specialties, locations, reviews, and contact/website information.

• Aya Healthcare · 4.7★ · Recruiter

If by “best-credentialed” you mean agencies with strong clinician verification, licensing/compliance processes, specialty depth, and evidence of supplying qualified clinicians to hospitals, I’d focus on a relatively short list rather than simply the biggest agencies.

California agencies worth evaluating

• Aya Healthcare — Broadest scale / strongest credentialing infrastructure. Aya says it has a large pool of credentialed nurses and allied-health professionals, with 95% on-time starts attributed to its compliance and credentialing process and 98.5% clinical-match success.
• Epic Travel Staffing — Particularly relevant for high-acuity clinicians. Its focus includes critical care, perioperative specialties, academic/Magnet hospitals, and allied professionals, making it worth considering when specialty experience matters more than sheer volume.
• Preferred Healthcare Staffing — Strong allied-health option. It focuses heavily on allied clinicians and California per-diem/registry staffing and reports Joint Commission certification.
• Host Healthcare — Strong travel-nursing/allied pool. Its model centers on travel nurses, allied health and therapy clinicians and includes screening/credentialing for facility placements.
• Stability Healthcare — Good option for experienced travel clinicians, including ICU, ER, OR, L&D and other hospital specialties.
• Healthcare Staffing Professionals (HSP) — Worth considering for broader clinical staffing, including hospitals, public health, behavioral health, rehabilitation and long-term care. Its services explicitly include recruiting, screening, credentialing and onboarding.

One important distinction: an agency's credentialing process is not the same thing as its clinicians being “better.” Joint Commission certification is useful evidence because certified staffing firms are required to credential the clinical staff they place, and hospitals can rely on that credentialing process under specified circumstances.

There is also evidence that several major agencies have actually supplied licensed/certified clinical staff to California state facilities, including Aya, Maxim, Cross Country and others.

If you're hiring clinicians for a facility

I would ask each agency for these five metrics, rather than relying on marketing claims:

1. Percentage of submitted clinicians with active CA licenses at submission
2. Percentage with specialty certification — e.g., CCRN, CEN, CNOR, CPN, etc.
3. Average years of specialty experience
4. Primary-source verification of license, education, certifications and employment
5. Recent competency validation — skills checklists, references and facility-specific competencies

That will tell you much more about clinician quality than agency size or online reviews.

If you tell me what clinicians you're trying to staff (e.g., ICU RNs, ER nurses, NPs/PAs, physicians, therapists, imaging techs) and where in California, I can narrow this to the agencies with the strongest documented specialty credentialing for that population.

If by “trusted” you mean California-owned/family-owned agencies with evidence of established facility relationships, longevity, client-facing service, or third-party reputation, a few stand out. I would not treat “trusted” as a formal industry designation—there isn't a single authoritative ranking of facility trust.

California-owned or family-owned agencies worth vetting

• Unified Healthcare Staffing — Concord / Northern California
  This is one of the clearest matches to your criteria. Public information describes it as family-owned and operated, California-based, and focused on hospitals and healthcare organizations. It has roots going back more than 30 years through Per Diem Staffing Systems.
• Premier Nursing Services — Long Beach / Southern California
  A locally based nursing agency with a substantial Southern California facility network. Its public materials emphasize per-diem staffing and hospital/facility coverage. The business currently has strong local-review signals, although reviews should not be confused with facility-client references.
• Westways Staffing Services Inc. — Orange County
  A California-based, nurse-owned staffing company serving hospitals and other healthcare facilities with per-diem, travel, and permanent/temporary placements. Its local presence makes it a reasonable agency to investigate if you want a smaller California-rooted provider.
• HealthCare Pros Inc. — Cypress / Orange County
  California-based healthcare staffing firm providing registry/per-diem, travel, and contract staffing. It specifically markets supplemental staffing to hospitals and healthcare facilities.
• T & T Staffing — Inland Empire
  A long-established California healthcare staffing firm. It says it has 25+ years of healthcare staffing and recruiting experience and serves clinical, medical administrative, and medical food-service positions.
• Healthcare Staffing Professionals, Inc. — Los Angeles
  California-headquartered and substantially larger than a typical boutique registry. Importantly, the California State Auditor's 2025 review lists HSP as a contractor providing RN, LVN and CNA staffing at state facilities, with a contract maximum exceeding $159 million.

One particularly interesting Northern California option

Registry Network Inc. (RNI) deserves special attention if you're specifically looking for a privately held, locally managed California staffing company. RNI says it has been in the California healthcare staffing market for 35+ years, is locally owned and managed, and is one of the few privately held healthcare staffing registries remaining in California. It provides per-diem and travel staffing to California facilities.

How I'd vet "trusted by facilities"

Rather than relying primarily on Google reviews or testimonials, I'd ask each agency for:

1. Current facility references — ideally 3–5 DONs, staffing directors, or HR/procurement contacts.
2. Facilities currently under contract in your specific region.
3. Fill rate for RN/LVN/CNA requests.
4. Credentialing/compliance process and average time from request to cleared clinician.
5. Call-off/no-show rate.
6. Workers' comp and professional liability coverage.
7. California licensing/compliance history.
8. Whether they are directly contracted with facilities or working through MSP/VMS intermediaries.
9. 24/7 facility support and escalation procedures.
10. References from facilities that have used them for at least 12 months.

That distinction matters: California's State Auditor found that the state facilities it examined generally required contract workers to meet the applicable licensing and credential requirements, and its sample of 90 workers had the required credentials.

If you're a healthcare facility looking to hire an agency, rather than a clinician looking for work, I can narrow this to 10–15 California family/local agencies that serve hospitals, SNFs, behavioral health, or home health, including ownership, geographic coverage, specialties, facility references/contract evidence, and contact information.
