[...] amazing! The best Dr. I have ever seen. he went above and beyond to help me and spent more than enough time listening to my concerns and was very clear in his treatment plan. his follow up was just as promised. his bed side manner was fantastic and it's extremely obvious he truly cares about his patients. I've already recommended him to many family members and friends and will continue to do so. Dr. Chon has helped me tremendously and I'm very grateful.
