Dr. Hsin-Yi Chang, MD, FACS
Bariatric Surgeon

“The ideal patient-doctor relationship is one in which both people are listening and learning. I want my patients to understand the pros and cons of every procedure we are discussing. Together, we will find the best path forward.”

Background & Philosophy

Dr. Chang is recognized for her expertise in minimally invasive surgery, with a specialty in bariatric surgery designed to help patients achieve significant weight loss.  She embraces a collaborative approach with her patients, understanding that each individual (and their journey towards wellness) is unique.

Dr. Chang’s goal is to provide her patients with a better quality of life, and her greatest reward is watching them achieve life-changing outcomes following bariatric surgery. Although the procedures she performs take relatively little time, the long-term results are extraordinary, in terms of overall health and life expectancy.
