Very good all around experience with Dr Chao

Dr Chao put me at ease the minute I met him for my pre op! He was personable, knowledgeable, and helpful. His explanation of my procedure was thorough and complete. He made sure that when we left all of our questions were answered (we had very few due to his complete explanation). He also was quick to respond when one of my doctors contacted him the day before my surgery with a question. On the day of surgery he again made sure we were confident about the procedure. Just can't say enough about the positive experience I had with Dr Chao.
