Internal Medicine involves the diagnosis and treatment of pathology involving the internal organs of adults. Through years of training, the physician gains extensive knowledge of the proper function of the internal systems as well as a thorough comprehension of the symptoms of disease and injury.

Osteopathic Medicine offers a holistic approach to traditional medicine. With his or her hands, the physician is capable of diagnosing, evaluating, and treating the body's systems, thereby supporting the theory that the body has the capacity to heal itself. Certainly, we recognize that these manipulative techniques are supplementary to traditional medical care.

Hackettstown Medical P.C. offers extended services from the hours open to the procedures performed. We support a holistic approach to medicine - the philosophy under which the physician has trained.
