What People Are Saying

"When I first met Dr. David Chang I felt that I was at my rock bottom. We started with acupuncture, which helped my knees dramatically. Shortly after starting treatment he introduced me to Prolotherapy and Ozone treatments, and the results have been unimaginable! Because Dr. Chang never gave up on me, I have been able to address so many of my health issues. I feel that I have been given a real chance to get out of my wheelchair in the foreseeable future, and even live my day to day life without the constant pain. I truly believe that I could not have come this far without his holistic, and unique approach to pain management. I would recommend Dr. David Chang to anyone who suffers from chronic pain and other long term illnesses. He has truly changed my life." -Michelle H
