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!

Kathleen M • September 03, 2025

Office staff is always friendly and helpful. Love the front desk ladies! Sorry I am sometime absent minded. I don’t want to leave anyone out because even the medical assistant that listen to me complain about taking my weight andShow more take my vitals. The ladies that take care of medical records and referral. Couldn’t be happier with my choice of a doctor. I feel doctor sim actually cares about my treatment. Thank you all for everything you do for me!
