We’re winners of ClearlyRated’s “Best of Staffing” award four years in a row & we’ve been recognized as a perennial “Largest Locum Tenens Firm” by Staffing Industry Analysts.

Specialized Focus

We stay ahead of the changing world of medicine by focusing on the specialties in greatest need: Primary Care/Family Practice, Internal Medicine, Hospitalists, Emergency Medicine, and General Surgery.

QualityCare Staffing

We conduct some of the most rigorous screening and performance measurement processes in the healthcare staffing industry. Over 95% of our facilities would have our providers back, and over 95% of our physicians would return to a facility.

I have worked with Interim Physicians for more than 10 years and it has been a pleasure to work with this organization. Everyone I have worked with are helpful, caring, prompt, professional, and knowledgeable. The staff provides the best advice and listens to my concerns and needs. During my time at Interim Physicians, I have worked with Miss Tina Lenihan for more than 10 years. Because of our long, working relationship, she is very much aware of what I am looking for in an assignment without having to contact me. She has always given me the best and satisfying assignments. I highly recommend Interim Physicians to any provider who is looking for an experienced company that can provide a broad and diverse spectrum of assignments.

This recruiting agency is the best I've had in my 12 years of locum tenens. My agent most of that time has been Tina Lenihan and she is superb! She is honest, trusting, an excellent communicator and very sympathetic to my needs. I can recommend this agency without reservations!
