Our Team

MED-1 Occupational Healthcare Team

We are leading professionals in occupational medicine. As people, we take pride in honoring and respecting the individual in any communication or care process. As professionals, we take pride in delivering the highest quality medicine that in turn results in the most cost-effective care.  Our MED-1 clinical team is made up of professional medical, nursing, and physical therapy staff with certifications in all areas of occupational medicine and healthcare. Our organization is physician-based which means there is always a doctor available to see appropriate patients.

While the medical staff focuses on occupational healthcare, MED-1 Clinic Managers make sure operations and communications run smoothly. It’s all part of our employer-focused program to provide excellence in clinical management, to return your employees to their work responsibilities, and to give you Personal Service and Professional Results.
