Andy Yu-How Chang, MD

Dr. Chang graduated from Stanford University with a B.S. in biological sciences and continued his education at USC for medical school and residency training in urology. Afterward, he matriculated to the prestigious pediatric urology fellowship program at Children’s Hospital of Philadelphia and University of Pennsylvania. While in Philadelphia, he distinguished himself as a superb researcher. He was also awarded a scholarship by the American Urological Association Foundation and appointed a National Institutes of Health sponsored researcher. Chang has garnered multiple awards at society and national meetings. Most recently, he contributed to the best basic science paper awarded at the 2008 American Academy of Pediatrics Section on Urology Meeting.
