Dr. Sims is the consummate professional. We met him at the Cath Lab at Eastside. He was highly recommended to us by our favorite internist. He is very approachable. He explains complex conditions and treatment options in a clear,straightforward way. He never acts as if he is "too busy' to spend quality time with his patients. He shows his patients and their families respect; he is NEVER condescending! When expertise and an excellent bedside manner is important, he is the BEST choice

Worst phone response that I have ever encountered from a medical provider. I've called numerous times for a variety of reasons - to change appointment, talk to nurse, get general information. ALWAYS routed to an answering machine and NEVER get a callback within a reasonable time frame. Terrible Customer service - Beyond POOR! These people act as if no one has a life but them. If I ran my business this way, I would be out of business in 6 months. (celebrating 40 years in December) Good Luck !

Dr. Sims is an incredibly efficient and genial physician. Great bedside manner and very direct. He and his staff make you feel like you're in very capable hands. I will recommend him to anyone.

I went to Dr.Sims shortly after moving to Grayson. I was being treated for non-lifethreatening afib. As the afib episodes became more frequent I became more fearful and my quality of life diminished. Dr.Sims seeing my distess refered me to an electrophyiologist to repair my heart. I was so grateful that he was willing to let another doctor take over to improve my quality of life. Dr.Sims is one of the finest doctors I know. Caring, intelligent, funny and kind I am so blessed by being his patient

On Nov. 29,2016, my wife suffered a heart attack at home in Stone Mountain and was transported to Eastside Medical in Snellville. Upon arrival she was immediately set up for catheterization. That's when Dr. Marcus Sims came into the picture. Two stents later she was on the road to recovery. Dr. Sims not only did a wonderful job but explained everything in terms laymen could understand. He gave assurance and encouragement. Bedside manner is unbelievably good. He is a great listener. He is our Dr.

Dr. Sims is by far a different kind of doctor in todays world. He did a heart catherization on my mom and placed a stint for a 95% blockage. He spoke to my sister and I afterwards and made us feel completely comfortable. Upon seeing him in the Monroe Office with my mom a week later he listened to my moms concerns and when the visit was over hugged both our necks this is something you do not see in the medical field very much any more. I loved hearing his story of how he got in the medical field.

Want to thank Doctor Sims for my father. Great specialist, calm, confident person! First my Dad was afraid to go to the Medical Center)) but Doctor Sims gave the sense of confidence, was very friendly and compationate. He explained in smallest details everything we needed to know about father's treatment. All best wishes to doctor Sims from our family!

Dr. Sims has truly been a blessing in my life!!! Upon meeting him, his genuine sincere and compassion made me feel at home as soon as I met him. This is a quality not many healthcare professionals possess these days. Bed side manners are truly the best and I will be recommending him to all my friends in need of a heart specialist!!! Again thank you for taking well care of me and GOD SPEED!!!
