Patient Reviews

Nov 30, 2022

I have been seeing Dr Sim for 5 years now after not being happy with my previous PCP. Dr. Sim was very attentive and immediately suspected and appendicitis and sent me to ER and it sure was, I had an emergency surgery. I most cases he has provided an accurate diagnosis, lab work as needed and any other test. He is very thorough and passionate.
