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!

Stevens in Ansonia, CT – Jan 13, 2017
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.
