My care was excellent. Dr. Duythuc knew exactly my condition and encouraged me and changed my medications because there was something I needed to be looked at. So he was very attentive to that, which I appreciate. I had a good experience and I've been in good hands with him and with his staff. He listens very well and I appreciate that. So thank you very much. Have a wonderful day.

Dr. Thomas To is amazing. He's the best cardiologist I've ever seen. Him and his whole group of employees at the office were great. And he's just a really nice man. He listens to you. He always asks you if you have any questions. And I just feel real comfortable with Dr. Thomas To.

All the people that I had dealings with treated me with respect and were extremely helpful as to things that I needed to do with other appointments and tests
Feb 11, 2026
I like Dr. To a lot. I only had to explain to him once why I made the appointment with him. It took him less than 2 minutes to compare the 2 Electrocardiograms and find there was no anomaly. Then he gave me a Procedure/Surgery Clearance Form that I can use to proceed with the EGD test my P.A. requested, plus provided me with a Lipid Panel for my appointment with him in 6 months.

Great guy! Dr To is the best at what he does

My care provider didn’t volunteer information. I had to ask questions. He always asks me if I should take a medication… I don’t know, I’m not a doctor. I go for information, advice and a treatment plan. My job is to provide symptoms, and follow through on the treatment plan. I’m happy that we have a plan.

Staff was great & took me in early which I appreciate.
