Chiropractic Waterloo, Dr. Erika Holenski

Dr. Erika Holenski, B.Sc., ND, R.Ac

Naturopath Registered Acupuncturist Clinic Director

It is my philosophy that the human body has an innate healing system. This system can fight infections, and correct deficiencies and other imbalances. The body, however, can be overwhelmed and not be able to restore harmony. When this occurs the body communicates to us through negative signs and symptoms.

Using patient history, physical exam and diagnostic tools I am able to see where the body’s imbalances lie. Then, I can provide ways to shift the body back to equilibrium. Together with the patient we develop a plan of action to overcome these obstacles to cure and stimulate the body’s natural healing system.
