Dr. Caldon Haj, MD
Hi, I'm a physician and creative
based in San Diego, California.

About Me.
I'm Caldon, a board certified physician in internal medicine and obesity medicine. I believe in "positive medicine", that methodology is motivated by patients' need for a more comprehensive care. It works by assessing the whole body and lifestyle in order to prevent diseases, rather than treating diseases after they happen.
