Top 10 Anesthesia Staffing Agencies in the US and What Makes Them Stand Out

Anesthesia staffing has become one of the more complicated operational challenges in healthcare. The shortage of qualified anesthesiologists and CRNAs is real, and it has pushed a lot of surgical facilities into a position where they are leaning on staffing agencies more heavily than ever before.

The problem is that not every agency is built the same. Some are large generalist firms that handle dozens of specialties and treat anesthesia as one line item among many. Others focus specifically on anesthesia, which tends to produce better outcomes for facilities that depend on consistent, reliable coverage.

This article breaks down the top 10 anesthesia staffing agencies operating in the US right now, what each one does well, and what to keep in mind when making this kind of decision.

What Actually Separates a Good Anesthesia Staffing Agency From a Mediocre One

Before getting into the list, it helps to know what you should actually be evaluating. Slick websites and big claims are everywhere in this space.

The factors that matter:

• Provider network depth. How many actively available providers do they have in your region, and what case types can those providers cover?
• Credentialing process. Do they verify licensure, DEA registration, board certification, and malpractice history before placing anyone? Or do they move fast and skip steps?
• Coverage flexibility. Can they handle locum tenens, PRN, and permanent placement? Or are they a one-trick operation?
• Speed without shortcuts. Fast placement is valuable. Fast placement that skips credentialing is a liability.
• Support after placement. Do they stay involved once a provider is placed, or disappear until the next invoice?

Keep those in mind as you read through the agencies below.

The Top 10 Best Anesthesia Staffing Agencies in the US

1. 1MAC Anesthesia

1MAC Anesthesia is one of the more focused agencies in the space, built specifically around connecting anesthesiologists and CRNAs with facilities that need coverage. That specialization matters more than people typically give it credit for.

What sets 1MAC apart is the combination of speed and thorough credential verification. They maintain a pre-vetted provider network, meaning when a facility reaches out for coverage, providers are already credentialed, licensed, and ready to be matched. For facilities dealing with unexpected gaps or last-minute schedule changes, that kind of readiness makes a real operational difference.

They work with W2, 1099, and locum tenens arrangements and can staff both anesthesiologists and CRNAs. 1MAC handles everything from initial request through credentialing support and ongoing placement management during anesthesia staffing. Facilities are not left managing the details themselves. They serve hospitals, ambulatory surgery centers, outpatient clinics, and specialty care centers across the country.

2. Nationwide Anesthesia Services

Nationwide Anesthesia Services is one of the oldest and largest full-service anesthesia-only staffing firms in the US. They specialize exclusively in anesthesiology, which gives them a depth of focus that generalist firms rarely match.

They cover locum tenens and permanent placements for both CRNAs and anesthesiologists, and they maintain a credentialing team that handles licensure paperwork and facility applications directly. They also provide malpractice coverage for providers on assignment and offer payroll services, which simplifies the administrative side for both providers and client facilities.

Their multi-decade track record and offices across several states give them solid regional depth in addition to national reach.

3. Harmony Anesthesia Staffing

Harmony Anesthesia Staffing is a clinician-owned agency out of Atlanta, run by practicing anesthesia providers including CAAs, CRNAs, and anesthesiologists. That ownership structure is genuinely different from most agencies, and it shows up in how they operate.

They place providers in locum tenens, PRN, and permanent roles across hospitals, ambulatory surgery centers, and anesthesia practice groups nationwide. Their model emphasizes price transparency and sustainable staffing solutions, and they back it up with weekly payroll and a profit-sharing program for providers.

For facilities, the clinician ownership means their team actually understands OR dynamics and case mix requirements in a way that non-clinical staff often do not. Strong reviews from facility directors point to consistent provider quality and smooth credentialing.

4. CompHealth

CompHealth is one of the largest locum tenens firms in the country and has a well-established anesthesia division. They have been operating for decades and bring a broad provider database and significant national footprint.

Where CompHealth performs well is in infrastructure. They have dedicated credentialing teams, travel coordination, and malpractice coverage for locum providers, which reduces the administrative load on facilities considerably.

The tradeoff at this size is that anesthesia is one specialty among many they staff. Facilities with very specific case mix needs sometimes find the matching process slower and less precise than with a more focused agency. Their strength is volume and reach.

5. Jackson + Coker

Jackson + Coker is a major locum tenens firm with a strong national presence and a solid anesthesia offering. They have a large recruiter network and are generally well-regarded for handling longer-term locum placements.

For facilities looking for extended coverage over several months, Jackson + Coker can be a capable partner. Their credentialing support is reliable, and they have experience managing the paperwork complexity that comes with cross-state locum placements.

Like CompHealth, the generalist nature of the firm means anesthesia is not their sole focus. For complex or urgent situations where specialty depth matters, a dedicated anesthesia agency will usually produce faster and better-matched results.

6. Premier Anesthesia

Premier Anesthesia, part of the Jackson Healthcare family of companies, has been building and managing hospital-based anesthesia practices for over 20 years. They operate more as a full-service anesthesia management company than a traditional staffing firm, offering complete department management, financial services, consulting, and recruiting under one roof.

Their size and reach through the Jackson Healthcare network give them access to a large provider pool. They serve hospitals and ambulatory surgery centers primarily and bring a structured approach to both short-term coverage and long-term department management.

For facilities that want to outsource broader anesthesia operations rather than simply fill individual gaps, Premier Anesthesia is worth evaluating.

7. LocumTenens

LocumTenens has been placing locum tenens anesthesia providers since 1995. They operate as a full-service recruiting and staffing platform with a dedicated anesthesia team, covering general anesthesia, pediatric anesthesia, cardiac anesthesia, and pain management.

One notable aspect of their model is recruiter specialization. Each recruiter focuses on a single medical specialty, which means the person handling your anesthesia request is not also managing a physician search or a nursing contract. That focus tends to produce better provider matches.

They serve facilities across the country and handle the administrative and travel coordination side of locum placements through an established system built over three decades.

8. Staff Care (AMN Healthcare)

Staff Care operates under the AMN Healthcare umbrella and is one of the largest healthcare staffing networks in the country. Their sheer size gives them access to a very large pool of providers across virtually every specialty, including anesthesia.

For health systems that already have AMN contracts in place for nursing or other clinical needs, adding anesthesia coverage through Staff Care can simplify vendor management. The consolidation is appealing from an administrative and contract standpoint.

The downside mirrors other large generalist operations. Anesthesia gets handled like any other specialty in a high-volume system. Facilities with specific staffing structures or unusual case mix requirements sometimes find the experience less tailored than they need.

9. Independence Anesthesia Services

Independence Anesthesia Services (IAS) focuses exclusively on anesthesia locum tenens, placing anesthesiologists, CRNAs, MDs, and DOs in facilities across the country. Their anesthesia-only focus means their credentialing team and recruiters are not splitting attention across other specialties.

They emphasize provider vetting beyond just credentials, including alignment with a facility’s culture and case expectations. They also offer a locum-to-perm pathway, which allows facilities to evaluate a provider on assignment before committing to a permanent hire at no additional cost.

IAS serves facilities of all sizes and is a solid option for facilities looking for a focused locum tenens partner with a clear conversion pathway.

10. Somnia Anesthesia

Somnia takes a different approach than most agencies on this list. They operate as an anesthesia management company, typically taking over a facility’s entire anesthesia department rather than filling individual positions.

They bring their own management infrastructure, billing processes, quality oversight, and provider network. For facilities looking to fully outsource anesthesia operations, Somnia offers an end-to-end solution.

The limitation is that this model is not a fit for every facility. Hospitals and ASCs that simply need to fill specific coverage gaps and maintain internal control of their anesthesia department will likely find Somnia’s model more than what the situation calls for.

How to Use This List

No single agency on this list is the right answer for every facility. The best fit depends on your specific coverage needs, case mix, facility type, and how much administrative bandwidth you have internally.

That said, for facilities that want a true anesthesia-specific partner with fast credentialed placement, flexible coverage types, and hands-on support throughout the process, 1MAC Anesthesia consistently comes out as the strongest operational match for most hospitals and ASCs. 

The others on this list each have real strengths, but most of them either operate at a generalist scale that dilutes the anesthesia focus, or they take a broader management approach that goes well beyond simple staffing coverage.

A Few Things Worth Remembering

The agency you choose becomes a real operational partner. You want one that communicates clearly, verifies providers thoroughly, and stays engaged after placement. These are not guarantees you get from brand size or market reputation alone.

Ask every agency on your shortlist the same direct questions: how do you verify your providers, how fast can you place in my region for my specific case types, and what happens if a placed provider is not a good fit? The answers will tell you more than any marketing page will.

Anesthesia staffing is not a commodity purchase. Take the time to find the agency whose model actually fits the way your facility runs.
