Dr Chang did my rarp surgery in May and this was my 6 month visit. Dr Chang did an excellent job in my surgery with no real complications. I had minimal incontinence from day one and am now back to near normal. Dr Chang has always provided quality of time, patiently answering my questions, and sympathetic to my situation and and the seriousness of my cancer. I have been cancer free from date of surgery and owe this to the experience and professionalism of Dr Chang. I do believe that he saved my life.
