Dr. Chang has been my Cardiologist since 2001 and has performed numerous complicated procedures on me with successful results. He is masterfully skilled, has a wonderful personality and very patiently explains to you in detail the answers to any questions that you may have. I trust him in every way! Theres no doubt that he is an Atlanta Top Doctor! It doesnt get any better than Dr. Chang!

Dr. Zhang is the best cardiologist I have ever met in Atlanta. He is very concerned about his patients. Whenever we ask a question to his office, I get a quick reply and answer the question. My familys heart is deteriorating. His face has long been pale. After Dr. Dhang puts in a defibrillator and adjusts the medicine, my familys face looks more rosy and healthy. We are very grateful to Dr. Zhang and his team members. It is really grateful to provide such a quality and caring service,really appreciated.
