Horrible experience
Stared at his computer entire visit with his back to me, demanded answers to irrelevant questions in an accusatory (inquisition like), manner and then took issue with every single response given to him. He also refused to look for, and view relevant records that had been forwarded to him in advance, refuted ESTABLISHED AND LONGSTANDING DIAGNOSIS by previous providers without any basis. Obviously, he was uninterested in hearing or knowing anything about me; cold, arrogant, dismissive. If he doesn't want new patients, why accept them? It would be better then abusing them.

--does not return calls. had blood test results with numerous danger signs indicated. could not get doc to return my call to discuss. I have no idea if I'm sick with something major or not. --asked for a blood test last summer due to thyroid concerns - was in another state having symptoms. refused to fax the request to a lab i the state I was in because he thought insurance would deny it. so he wouldn't help. had to order and pay for my test result myself and it indeed showed numbers that were off so I needed to adjust my meds myself. They used to be so much more responsive and professional. One of the office staff is exceptionally rude too.

Today I went back to visit Dr. Chao after some recent blood work. He was as professional, patient and caring as he was on my first visit. Can't say enough great stuff about Dr. Chao. Coming from Long Island N.Y. and recently moved here I would say I hit a HOME RUN with Dr. Chao! His staff are all friendly and caring. Battling - Battaboom

One of the most thorough professionals I've known. He's local so I picked him out of the insurance website. Well, did I get lucky and hit a home run! Very comprehensive physical exams. And responds promptly to messages and his portal. Can't ask for more. p.s. Polite and helpful office staff too.

I have been a patient of Dr. Chao for many years. Despite my having moved to Florida, I still come to see him at least once or twice a year in CT. He is a very caring doctor and I would highly recommend him to anyone with Asthma and/or allergies.

My husband and I have been with Dr. Chao for several years on the recommendation of a friend. I couldn't be happier with the care he gives and the compassion and concern he has for us. He is very knowledgeable and I always feel at ease and well educated regarding diagnosis when I've seen him. His "bedside manor" is spot on - always personable and professional. He's the best!

Dr. Chao has taken excellent care of me, my allergies, and COPD lungs for over 30 years! Dr. Chao is a superb, warm, and brilliant physician who, when needed, goes way beyond normal professional expectations. When he moved his office to Shelton, I continued to drive from Westport . He is the reason that I am breathing in and out today. I give him the highest 5 * recommendation! Sincerely, Kate Stuart-Gray, L.C.S.W.
