Appointment was an initial consult for possible surgery. Dr. Uy was very personable and explained all the options. He was easy to speak with and the follow-up office contact was professional.
August 9, 2025John F.Verified patient
My Family has seen Dr Oy in the past for many years. He has done a variety of surgeries , which is amazing to me, because I never realized how much a "general surgeon" As Dr Oy is, was knowledgeable to do many surgeriies on different areas of the body with such expertise..Wonderful Doctor, wonderful bedside manner. Doctor takes the time to answer all concerns in terms I can understand. Very thorough, providing additional information I may have forgotten to ask. I can't praise him enough. From the simplest of surgeries such as simple cyst, lipoma, to a surgery such as gallbladder & other parts of ones body is within the scope of a general surgeon.

Dy Uy is very nice and very professional. Thankfully I did not have the problem I went to see him for. I used him 5 years ago for surgery, and I wouldn't want to use another surgeon in the future.

Honest doctor.
January 6, 2022Joe P.Verified patient
I found the physician to be extremely professional, kind and had an exceptional bedside manner. His MA Anthony was also very professional and has a very good bedside manner. Unfortunately, I did not find the support staff to be very warm at all. A smile and a kind word would go a long way.
December 21, 2021Debra D.Verified patient
Dr. Uy is very knowledgeable. He’s friendly, listens and communicates in details as to what the plan is. I’ve used him before - will use him now & will book with him in the future if anything arises.
