Holistic Family Practice medicine


Practice philosophy

Thiensville Family Health Care employs the model of Holistic Family Practice. This is an integration of traditional Western medicine, including diagnostic procedures, with those complementary therapies that have valid scientific research. The patient- physician relationship is viewed as a partnership in which the patient assumes joint responsibility in his or her healthcare. The physician provides the patient with the relevant treatment options for his/her particular medical condition and the patient is able to make an informed choice for treatment. The physician thus will guide and monitor the treatment process.

In addition to his holistic medicine approach, Dr. Lewis chooses to practice as an independent physician because he values the personal relationship between doctor and patient. In this day and age of large physician groups, impersonal clinics and specialized medicine, the personalized care delivered  by Dr. Lewis to your entire family is rare to find.
