Weaving Internal Medicine with
Integrative Medicine to Use the Best Each Has to Offer

Simon Yu, MD

My approach

“Think differently! We must correct the underlying problems that cause our illnesses. By doing so, our bodies correct themselves and return to optimal health.”

We help patients on their journey and quest for health, developing tailored plans to combat hidden health threats, and restore the body’s condition of a healthy terrain.

We help doctors and dentists learn forensics to detect hidden health threats by offering training on Acupuncture Meridian Assessment Training (AMA).

We provide educational resources for those who want to learn more about the root causes of chronic diseases, how to detect and address them, and help restore health.
