Patient Reviews
Jan 04, 2018
Both my 84 year old mother and 92 year old father have been patients of Dr Mager the past 10 years. Tesla said, "instinct is something which transcends knowledge," and Dr. Mager successfully uses both his keen instinct and extensive fundamental knowledge in treating his patients. He is current on the latest treatment innovations. He not only treats symptoms but the cause of an illness addressing the needs of each individual patient. I've referred my closest friends. Thank you Doc.

Board Certifications
What’s a board certification and why is it important that my provider has one?

A board certification represents a provider’s dedication to ongoing training in one or more specialties, including the completion of intensive exams. While not all specialties have board certifications, if your provider does have one they’ve taken the extra step to master their specialty and to keep up with the latest advancements in their field.
