Testimonials

"Dr. Hyon is by far the best orthodontist you will ever have because not only does she have great bedside manners but you genuinely feel that she cares for you. She always went out of the way to make it easier for me as a patient and I don’t see that in doctors that often. Her staff are friendly and competent and her offices are clean and professional. Personally I struggles with tmj which caused severe neck and shoulder pain for several years. I even saw an tmj specialist prior who claimed they could fix my bite but in the end it was a waste of time and money. After correcting my bite and making my smile so much better after about a year under Dr. Hyon’s care, my pain was resolved! I am forever indebted to her and will gladly refer anyone to her! Thank you Dr. Hyon!"

"KHL orthodontics is amazing! I am beyond happy with my experience with Dr. Hyon. She is knowledgeable, friendly, and caring as are the rest of the staff. Since the moment you get in the office, you have a super comfortable and welcoming feeling. Dr. Hyon is professional and she will provide you the best option for your individual case. I highly recommend KHL orthodontics to make your new beautiful smile come true!"

"A big thank you to dr. Hyon and her team. I am amazed by my results, but also with the entire process from the beginning till the end. They are welcoming, flexible and professional."

"I chose this doctor because her office was conveniently located in midtown by my office. I finished my treatment program yesterday and couldn’t be happier with the results. This doctor is not only a warm and wonderful human being, but she is also a patient and skilled orthodontist. She was very attentive to my concerns and expectations, and accommodating to my schedule for emergencies. I highly recommend this orthodontist."
C.S.
"Had fixed braces with Dr. Hyon as an adult. The results are really good both aesthetically and functionally! I had short roots from previous treatments and all other doctors were very cautious about me doing braces again, but Dr. Hyon was pretty confident in getting me good results without causing issues and did!"
