Most medical doctors direct their diagnosis and treatment toward disease, acute infection and serious trauma. However, conventional medicine often doesn't have the answers for the patient with functional illness, in which the person doesn't feel well and has any number of symptoms, but does not have a readily diagnosed disease. Often patients complain of chronic headaches, fatigue or back pain, only to be told they are "as healthy as a horse," or they will "have to live with it" or "it's in their head."

Holistic providers are needed to fill in the gaps left by conventional medicine. They are trained to see health issues along a spectrum from optimal health to disease.

Holistic chiropractic care is not a substitute for medical care. Dr. Sigman's work complements medical care. It does not take the place of regular medical exams, diagnostic procedures and treatment. Dr. Sigman prefers to provide care in conjunction with the medical community.
