I have always used the Christie Group. The efficiency with which they handle appointments is a HUGE plus for them. I live in Easley and I can almost literally call from my driveway with a sick kid and I have NEVER had to wait to see a doctor more than 10 minutes.
They also have a "new" doctor--Dr. Springle--who is FANTASTIC!!! I have three boys--one who is 13 and he really relates well to Dr. Springle. My daughter also just loves him. He is very concerned with keeping up with the kids in his care. My daughter is an eleven year old gymnast and has all of the related injuries. Dr. Springle makes sure to have me have the orthopedist share information about her care with him.
Good luck, I know this is a big decision!
