Dr. Sims is a very calming and enjoyable person to be around. He not only makes you feel very comfortable, but he is also interested in you and your family. He even sent me flowers after my surgery!! I don't know of any other Dr. that has done that. I would recommend him to anyone that is looking for a great periodontist. I had a gum graft done and I didn't have any pain during the procedure. He made sure I knew everyting that was going on and even made sure I was a part of it. His staff are very kind too.
