Dr. Sims is always attentive to my mom’s needs. He inquires about her activities and encourages her to adhere to his guidance. He is a personable and caring physician who seemingly sincerely cares about her well-being! I am extremely appreciative of his care for her.

Dr. Sims always takes the time to ask how I am, has anything changed, how my husband is even though he's not a patient, and any new meds from other Dr's.? And I feel like I don't always get that from all my other Dr's. Dr. Sims goes that extra mile to make me feel like I matter as a patient to him..

As a patient of Dr. Sam, I explained to him that they need to try to find another location every time I come to this location in Lawrenceville my wait time my parking space trying to get in to see Dr. Sams is very uncomfortable and unexperienced that I don’t wanna encounter at my age. I shouldn’t have to wait this long to see a doctor or family. Member is driving around trying to find parking space to be able to accompany me to my doctor visit please help and try to figure out a much more better location than the Lawrenceville location. Thank you.
