Hello! I’m Dr. Z

I’m a functional medicine physician, but in a sense I’m also a detective and a teacher.

…Because in my opinion, that’s what a good doctor is.

As a detective, I focus on the body’s “clues” to unveil the real causes of symptoms.

I also love being a teacher, and not just when I’m standing in the lecture hall or writing articles, but also when I’m working one-on-one with clients. I take the time to explain the nature of various medical conditions, the details of the body’s brilliance and physiology, and how to best support the healing process. I believe that education is power.
