Our Services

Specialty Care

GMG has developed a Specialty Clinic program in-house to better serve our patients.  We believe that by adding several key specialties to our practice, we can improve patient care through improved specialty access, coordination of care along with the Primary Care Physician, use of a common Electronic Health Record avoiding duplication of tests, and by providing specialty care that is aligned to our values and philosophy.   We have an excellent group of specialists that have enhanced our practice on several specialties. All specialists see established GMG patients only.
