Whole Family Medicine

Family practice is an approach to general medical care that includes all members of the family, from pediatric care to puberty, adult and reproductive years, to senior health care.
Keeping a family doctor helps create ongoing guidance and understanding by your doctor for not only your own life of health care, but that of your whole family, right from the beginning! It is common for Dr. Roberson to have multiple generations of a family within her care, from newborn babies great-grandparents !

What is a D.O.?

D.O.'s are Doctors of Osteopathic Medicine, fully licensed physicians who practice in all areas of medicine using a whole person approach to partner with their patients. The main difference in the training of DOs versus MDs is that DOs complete an additional 200 hours of coursework. This extra training focuses on bones, muscles, and nerves and how they affect the body's overall health. It also includes learning different OMM techniques to diagnose, treat, and prevent illnesses.
