I have been a patient of Dr Sim’s for 25+ years. He has treated me like family from the day I first met him! Through my healthy days and my very unhealthy days. I’ve had multiple serious health issues that he has diagnosed and tShow morereated. If he can’t treat it, he sends me to someone who can. I’ve had a lot of doctors over the years and he has been the ONE constant!! I put my trust in him time and again and I’m healthier in my 50’s than I was in my 30’s!!! Thanks Dr Sim!!

Dr Sim is a caring doctor. He sees you out and about and always says hi. If he sees you standing in line to check in and knows you’ve had some issues he gets your attention and asks if your ok. You can talk to him about anything, Show morenever rushes you even though I know he has plenty of patients waiting. He is an all round good doctor, good guy, and doesn’t hesitate in telling you that your doing good or you need to change something.

I've been going to Union Medical for 30+ years and have always felt like my needs were as important as the next person coming in for an appointment. I've recommended this office for others who are searching for a primary care provider, Dr Sim and Dr Biondo are both amazing and extremely caring for each of their patients.
