Dr. Sim is wonderful! He takes the time to listen and explains everything. Dr.Sim took care of me in the nursing home and now he takes care of me now that I'm home. Dr. Sim makes sure I get all of my meds in a timely manner aShow morend he makes sure they don't interfere with each other. I care for him not only as a physician but as a friend. The staff is also wonderful too. I had Dr. Biondo for many years but he had surgery and needed to cut back on patients. I really care about him too. Thank you!

Susan V • November 10, 2025

Dr. Sim is by far the very best doctor I’ve ever known and I wouldn’t trade him for anything. I live 30 to 40 minutes away now and I don’t hesitate to drive up to see him. I don’t consider looking for a doctor in this area becauseShow more I know I’m not gonna find anybody as good as Dr. Sim. Today their front desk staff was shorthanded so it was a struggle, but the people that work there are super kind, very polite and very helpful so even though things went bumpy everybody still did their best!
