I used Dr. Kim! I had my surgery on August 20th and I have nothing but great things to say! The staff was always very nice to me at every appointment! You don't see Dr. Kim a whole lot, but he came and seen me right before surgery and right after surgery! He's a very busy man:). I had no problems at all, back to work in 2 weeks, and I'm down 38lbs in 2 months! Hope I helped some:) good luck to you!!
