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!

Shelia P • September 29, 2025

Medication prescribed for a UTI has terrible side effects. I wish Dr Sim would taken the time to discuss with me what he was prescribing. Plus he order CT scan for my abdomen and pelvis with contrast…..I have stomach issues already and trying to swallow barium is not going to work ……but he did not discuss this with me at my appointment. Disappointing !! I have to call the office again on Monday to get a third prescription for UTI that my body can tolerate without throwing up all day !!

Belinda N • September 28, 2025

Had an 11:00 appointment that was scheduled for 3 months. The week of my appointment I was told that I needed to report to work earlier then normal. Instead of cancelling I arrived at 10:25 told the lady that checked me in that I needed to leave by 11:45. Got called back at 11:20 told the lady that did my BP that I only had A few minutes before I had to leave she said she will tell doctor. Doctor came in at 11:35 did not have much of a check up since I had to leave. Need full day for this place.
