Dale J. Ritzo, MD

My Philosophy and Approach to Wellness...

Healthy living, disease prevention, and personalized, timely medical treatment are what I want for myself and my family. I want my patients to expect those same things for themselves and it is my job to fulfill those expectations for each and every patient that I care for.
