The Family Physician

The family physician is a physician who is educated and trained in family practice — a broadly encompassing medical specialty.

Family physicians possess unique attitudes, skills, and knowledge which qualify them to provide continuing and comprehensive medical care, health maintenance and preventive services to each member of the family regardless of sex, age or type of problem, be it biological, behavioral, or social. These specialists, because of their background and interactions with the family, are best qualified to serve as each patient's advocate in all health-related matters, including the appropriate use of consultants, health services, and community resources.

All of our doctors belong to the American Academy of Family Physicians.

What is a DO?

Doctor of Osteopathy (DO) is one of only two medical degrees (the other is MD) that qualify physicians to acquire unrestricted licenses to practice medicine and surgery in all fifty states of the union. Like their MD counterparts, osteopathic physicians must complete four years of medical school and then pursue post graduate training in one of twenty-two areas of specialty such as family practice, internal medicine, obstetrics, emergency medicine, surgery or psychiatry. DO's comprise ten percent of physicians in the military and five percent of physicians nationwide. There are eighteen medical schools that confer the DO degree and over eighty that offer the M.D. degree.

DO's are unique in that their training includes the study and application of osteopathic principles and practice, a medical philosophy which stresses that the human body is a unified organism, a dynamic unit of structure and function with it's own innate self-healing properties. DO's are trained in Osteopathic Manipulative Treatment which is the hands-on application of the Osteopathic Philosophy. For further information regarding Osteopathic Medicine please go to American Osteopathic Association.
