Dr. Chu is one of the very best physicians I have ever seen. He cares about me & is thorough. I appreciate his guidance.

April 29, 2018 7:00 PM

1st time meeting with pulmonologist. My main issue is that I often get pneumonia due to my asthma. I just got out of the ER because of this. Instead of help with that issue Dr. Chu orders Stress Test, recommends again sleep apnea (in my chart and I don't have) and a pulmonary function test. I called back to the office and told them I wasn't going to take any of the tests. I will not be going back to that office, ever. My main reason was the lung infections I get, not stress test, sleep apnea, the ER and overnight stays in the hospital is what my entire issue was.

April 19, 2018 7:00 PM

Very kind and respectful. He explained everything to me.

March 27, 2018 7:00 PM

He is so nice, approachable & knowledgeable.

March 25, 2018 7:00 PM

Dr Chu was fine, but I had been prescribed medicines that were too expensive for me, and I had to make decisions based on price instead of health, and that is a bummer. I also had to take off of work for the appointment because the only hours he was available was during regular office hours (9-5), and I wound up almost losing my job and missing out on money because I thought that something might be wrong, only to be told that there wasn't a problem.

March 4, 2018 6:00 PM


January 14, 2018 6:00 PM

It was my first visit with Dr. Chu. He was knowledgeable and professional.

December 29, 2017 6:00 PM

December 28, 2017 6:00 PM

Excellent staff & doctors.

December 21, 2017 6:00 PM

Was not satisfy or even happy with her temporary fill in nurse XX. Provider Chu wasn't attentive enough not being understanding or patient. Taking time for what I had to say it was ____ he had to say.

November 16, 2017 6:00 PM

Very good.

November 11, 2017 6:00 PM

I recommend Dr. Chu, he is a professional in every sense of the word. Is very kind.

November 2, 2017 7:00 PM

Good experience. He was honest, courteous and considerate.

October 29, 2017 7:00 PM

Some of the question not applicable to me as this was my first and only visit with Dr Chue who has a excellent patient/doctor demeanor. I felt very comfortable talking with him as he examined me.

October 22, 2017 7:00 PM


July 16, 2017 7:00 PM

Very impressed with Dr. Chu.
