Our Difference
What makes us stand out from other providers? While there may be other companies offering occupational health services, what sets apart the exceptional providers is the combination of having an on-site medical doctor (M.D.) and holding board certification in the specialized field of occupational medicine. PromptCare OccMed possesses these distinguishing qualities.
