We have been under Dr. Sim's care for over 20 years. He has truly taken excellent care of both my wife and me with such attention and warmth. Thanks to his sincere advice and thorough examinations, we have been able to trustShow more him completely for such a long time. He is the best doctor we could ever ask for. We look forward to continuing our care with him!

Dr.Sim has been my GP since he first came to Havre de Grace more than 30 years ago. He was also my husband’s GP until he died. We have ALWAYS been extremely pleased with the care we have received from Dr.Sim, and we will greatly miss him when he retires!!! Margaret Mildred Harrison
I’ve been seeing Dr Sim for about 23 years. He told me today he’s retiring in June, ‘26. Major bummer!
