What Atom Physics does
Atom Physics is a privately held, bootstrapped medical physics staffing firm headquartered in Broomfield, Colorado, founded in 2011 by an ABR-certified medical physicist. The company specializes in placing board-certified medical physicists and dosimetrists into radiation oncology departments across U.S. hospitals and cancer treatment centers. Its core product is a relationship-driven staffing service offering three delivery models — traditional locum tenens (on-site), hybrid (on-site plus remote), and fully remote — each priced on a different cadence (multi-year contract, monthly retainer, and pay-as-you-go respectively). The company claims to be the largest and most reliable outsourced provider of medical physics and dosimetry locum services in the United States.
The company's value proposition rests on domain specialization and curated talent: all candidates are hand-picked and screened by radiation oncology professionals with experience across Varian, Elekta, and Siemens linear accelerators and the Eclipse, Pinnacle, Raystation, and Monaco treatment planning systems. The firm also operates adjacent service lines — X-ray machine inspections, lead shielding design reports, and dosimetry badge services — that cross-sell into the same facility relationship. Go-to-market combines a content marketing blog on medical physics topics, LinkedIn presence, direct outreach, referrals, and registration with multiple Managed Service Providers (MSPs) and Vendor Management Systems that route contingent healthcare workforce placements. Atom Physics is also engaged in a technology feedback partnership with IBA Dosimetry on its myQA SRS stereotactic radiosurgery QA system.
Atom Physics generates revenue through professional services fees for temporary and contract placements, billed at industry-standard locum premiums (approximately 2x regular salary for on-site coverage) and via recurring monthly or usage-based fees for hybrid and remote engagements. The customer base consists of radiation oncology departments in hospitals and clinics nationwide, segmented by use case — general locum coverage, rural or solo practice support, and budget-conscious departments seeking part-time or remote solutions. Operations remain tightly held, with 1-10 employees, no institutional investors, and the founder/lead physicist Adam Evearitt actively involved in contract management and candidate interviews.

Atom Physics competitors and assessment
Company assessmentBroad incumbents
- AMN Healthcare: AMN Healthcare is one of the largest US healthcare staffing firms, with a broad locum tenens and allied health portfolio. While not specialized in radiation oncology physics, its scale and MSP relationships make it the most consequential indirect competitor to Atom Physics.
- CHG Healthcare: CHG Healthcare operates several large locum tenens and permanent placement brands across physician specialties. Its national footprint and enterprise sales motion are highly comparable to Atom Physics's B2B staffing model, even though radiation oncology physics is not its primary focus.
- Jackson Healthcare: Jackson Healthcare runs a portfolio of healthcare staffing and workforce solutions brands serving hospitals and specialty practices. Its scale in allied and specialty staffing makes it a credible adjacent competitor for outsourced radiation oncology staffing contracts.
- CompHealth: CompHealth is a large locum tenens and permanent placement firm with deep physician and allied health coverage. Its relationship-driven sales motion closely mirrors Atom Physics's enterprise sales approach to hospital clients.
- Weatherby Healthcare: Weatherby Healthcare is a CHG-owned locum tenens staffing firm focused on physician specialties. Although it does not specialize in medical physics, it operates the same locum tenens contracting and credentialing model Atom Physics uses for its core staffing product.
- VISTA Staffing Solutions: VISTA Staffing Solutions is a long-standing locum tenens and international physician staffing firm. Its locum contract structure (13-week assignments, credentialing, MSP participation) is functionally equivalent to Atom Physics's traditional locum offering.
- Aya Healthcare: Aya Healthcare is a large healthcare staffing and workforce solutions company with strong managed services provider (MSP) relationships — the same channel Atom Physics uses to reach facilities. It represents the kind of scaled, MSP-integrated competitor that could expand into medical physics staffing.
- Landauer (part of Fortive): Landauer is an established provider of radiation dosimetry monitoring and radiation safety services. It overlaps with Atom Physics's dosimetry badge offering and is a credible reference point for the radiation safety/dosimetry services market segment Atom Physics operates in.
Emerging players
- Mirion Technologies: Mirion Technologies provides radiation detection, dosimetry, and radiation safety solutions to medical, nuclear, and industrial customers. While it is primarily a product company rather than a staffing firm, its dosimetry and radiation monitoring offerings overlap with Atom Physics's dosimetry badge and inspection services.
Others
- IBA Dosimetry: IBA Dosimetry is a global provider of quality assurance (QA) tools for radiation oncology, including the myQA platform Atom Physics evaluates. It is a technology partner and adjacent ecosystem player rather than a competitor, but its installed base defines the QA environment in which Atom Physics's deployed physicists work.
