Great doctor. I have seen him in the past and he is really good. There was a bit of a wait for my procedure but given the hightened safety precautions for COVID this was understandable.

Dr. Chu has taken good care of me. He handled my colonoscopy and endoscopy. Got to the root of my stomach problems and I am happy to say I haven had any severe symptoms ever since. He's very warm, professional and I feel comfortable seeing him. Highly recommend him to all.

I saw four different medical professionals that day. They were all located in close proximity to one another. His visit, Dr. Chu- was the most comfortable from the moment I stepped in his office. I am currently recommending everyone I'm my office and My Husband. Pleasant visit.
May 1, 2017Holly Y.Verified patient
I had just one time visit with Dr. Chu for my acid reflux. The secretaries in midtown office are not so friend, especially the older Chinese lady. She was talking loudly to her colleague about me in a negative tone right in front of me like i did not exist. The rude behavior had turned me off almost away. I still visited Dr. Chu. He seems to be professional and has in-depth knowledge. But I did not sense compassionate character of him. I need a warmer doctor who sincerely cares about his patient and knows what to say to put his patient at easy.

Accepts Aetna Elect Open Choice insurance for consultation, however, charges out of pocket (doesn't except insurance) for laboratory tests.

Dr Chu was very attentive and listened thoroughly to my concerns. He advised me of what he believed my issues were and also advised me of the process to investigate. He is a keeper! You don't find may physicians (regardless of specialty) that listen to the patient, look the patient in the eye and check into the patient's concerns BEFORE writing a prescription.
November 10, 2015Jacklyne H.Verified patient
It was my first visit and I arrived late but I was still seen, the staff and Doctor was very understanding. He listened to my concerns and medical issues reassured me made me feel at ease. Looking forward to my next visit and treatment plan.

Dr. Chu is honestly the best doctor I've ever been to. He takes time to understand your problems, and then helps put you on a path to get better.
He'll always call/write you back and do extensive research in finding you a specialist if you need it.

Dr. Chu was very knowledgeable and thorough in his diagnosis. He also spoke to me in a manner that I could understand given his specialty. I have a follow up appt with him in the upcoming weeks.
March 8, 2013Brendan D.Verified patient
Very attentive and thorough. I never felt rushed and felt like Dr. Chu was putting together a very complete picture of what was going on with me. He explained everything that he thought was going on, lifestyle factors, and how we would move forward with testing and treatment. His staff was great and got me appointments that I needed and always called back when they said they would.

I'm so glad I picked him! I laughed & I cried during the appointment and he made me feel great during both instances. I completely trust look into my stomach & diagnose me. I was so relieved when I left. The only thing that he may have lost points for had nothing to do with him. The next day I had to schedule an appt for a test but I never received that phone call. This now overshadows much of his qualities, but I still do trust his knowledge.
