For the eighth year in a row, Interim Physicians was named one of the “Largest Locum Tenens Staffing Firms” by Staffing Industry Analysts, a global advisor on staffing and workforce solutions.
The honorifics from SIA didn’t stop there. For the first time, Interim made its list of the Fastest-Growing Staffing Agencies in addition to the Largest Locums Firms list.
Following another record-breaking revenue year in 2024, Interim achieved notable recognition within the staffing industry as a whole. Our firm ranked #18 among the largest locum tenens agencies and #63 among the fastest-growing firms, an accomplishment that spanned all staffing sectors, not just healthcare.
“Our continued placement on these prestigious lists speaks to the unrivaled commitment of our team across all departments. Even with high demand for our services, each dedicated team member of Interim Physicians remains focused on our mission of delivering exceptional service and providing healthcare where it might not otherwise exist,” said Tim Hand, Chief Executive Officer of Interim Physicians.

Over the past year, the vital contribution of locum tenens providers to the US healthcare system has been more evident than ever. From handling patient surges and combating provider burnout to maintaining continuity of care until full-time professionals are found, locum tenens staffing from Interim Physicians is a proven staffing solution.
“Being named one of the largest and fastest-growing locum agencies in the country is humbling and gratifying,” said Shawn Mullen, President of Interim Physicians. “We proudly help our clients and locum providers fill healthcare coverage gaps with top-quality physicians and advanced practice providers in every corner of the country. These awards fuel our determination to meet any staffing challenge head-on and ensure local communities receive the care they need.”
SIA’s designation of Interim Physicians highlights the company’s legacy of excellence and innovation in the locum tenens staffing industry, dating back to the firm’s founding in 1979. As a trusted partner to healthcare facilities and providers alike, Interim Physicians continues to lead the way in ensuring essential healthcare services are delivered where they are needed most.
Mullen concluded, “We’re grateful to our clients and providers for trusting us as their staffing partner, and we’re excited to continue delivering excellence in every aspect of our services. Reaching new milestones in 2024 sets a strong foundation for even greater success in the years to come.”
