PentaHealth at Mount Airy Family Practice is a partnership of board certified family physicians and nurse practitioners. Family medicine is a medical specialty anchored firmly in the biological, clinical and behavioral sciences. We provide continuing, comprehensive healthcare for the individual while emphasizing the health of the family. Family medicine medical providers, like us, provide care for men, women, children and infants - there is no age limit to the patients a family medicine medical provider serves. There is no part of the body, no disease or condition excluded from the family medicine medical provider's care. In every sense, today's family medicine medical provider is what patients throughout history had in mind when they used the term "doctor." Our primary commitment is to excellence in patient care, we accomplish this with the help of our front desk staff, nurses, and medical assistants.
