Personally, Dr. Nguyen and the staffs are nice. I go to this office for over two years now, and it is very close to my home. However, Dr. Nguyen is always very brief and kick me out of the office quickly. Never get a good logical answer. This leave me feel worry about my condition and I had to make another appointment to see him again. May be he just lack of knowledge? I do understand his medical degree is not from a USA university, but he has over twenty years of practice?

My husband and I had been seeing Dr. Nguyen since 2014. We loved him and his staff. Dr. Nguyen was very efficient and caring. He stayed on top of our test results. Unfortunately we moved to Arizona in Aug. 2018. We miss him.

This is the worst doctor I’ve ever been to. I had a CT of my chest because I’ve been coughing for a few months. Went to see Dr. Nguyen 3 weeks after my scan. He saw scarring of my lungs but it was no big deal. As he continued with the scan he said I had a restricted airway but it was no big deal. I went and saw my primary care doctor feeling short of breath. They gave me a lung function test which should have been done with my Pulmonologist! My doctor confirmed stage 2 COPD. Avoid this doctor.

Our first visit was great introduction--no nonsense, professional and thorough. My wife and I left the office with the certainty that we had been given a clear diagnosis, a solid recommendation for the course of action to be followed and the reassurance that within the narrow range of my potential outcomes, if I follow his clear directions, my condition is manageable and will accommodate my natural "use by" date. Despite the crowded waiting room, this is business-like, no frills medicine.

I was a patient of Dr. Nguyen for years, prior to moving out of the area...I found his treatment to be excellent; he was thoughtful, polite, incredibly kind and considerate. I would recommend him highly to anyone, for anything.

Beware of this doctor. They are scheduled my appointment and I come on time. First they told me that they are not accepting my insurance even when I was scheduling the told me that they do, second, I asked them if they are in the Blue Shield network and they answewred its depends.....?!? They called to my insurance and they said that they are in the network and my copay is $8. I told them its ok and I know that, than they said that you need to pay $200 because your insurance doesnt pay on time??
