It was a good 1st experience.

April 4, 2020 12:57 AM

Provider answered all my questions and discussed everything away me and my parents understand.

April 4, 2020 12:57 AM

Best provider I have ever seen. Definitely recommend.

March 28, 2020 11:20 AM

I thought the provider did his best to provide excellent care.

February 14, 2020 6:53 AM

Dr. Guna was the worst - I would not recommend him. He got very upset that we (parents) were asking questions. He even asked us if "we were doctors" and proceeded to humiliate & belittle us. He got condescending in explanations. It was obvious he had not even read our son's chart - of which he later admitted as he caught us by the elevator. He even ordered a kind of test incorrectly and we had to return to get a new order.

Wonderful doctor, listened.

Dr. T.S. Gunasekaran is not only a phenomenal pediatric GI, he is family and the most important quality (though Dr. Guna has many) he respects me as an equal not just a "mom"!

July 5, 2018 7:00 PM

Dr. Gunasekaran was thorough, helpful, and patient. He listened to all of our concerns, developed a plan, and provided it in writing. We appreciate his expertise & help in working with our daughter.

Dr. T.S. Gunasekaran is an excellent pediatric GI! His assistant X is outstanding with his thorough research, work and always assists me with every aspect for my son.
