What Patients Are Saying

“It's always a pleasure to visit Dr. Chang's office. Dr. Chang is the kindest, supportive, and knowledgeable doctor I have. There's no office in Tampa that is as well decorated, clean, and of course the cookies are wonderful. This place And Dr. Chang needs more than five stars.”
- John’s 2018 Patient Survey Comment

“Have seen Dr Chang on 3 occasions over the last year. Once for a colonoscopy, then EGD and then as a follow up for my GERD. On each visit he and his office staff answered all my questions and were very thorough. Dr Chang spends time explaining and I feel well informed. Would definitely recommend him.”
- Marion’s 2018 Healthgrades Review

“I have been a patient of Dr. Chang for several years and I find him and his office staff are most kind and professional. I never have an issue getting RX refills or any or thing I may need. I get copies of all my test results and everything is explained to me. They also handle any insurance authorizations I may need for tests. I am thankful I can depend on them.”
- DMH’s 2018 Healthgrades Review

“I have had 2 recent great experiences. Dr. Chang listened to my concerns having had an ER visit a couple weeks prior. Made some suggestions and follow up. I had an initial appt with Gina Pratt. I thought she was extremely knowledgeable, patient and gave great recommendations.”
