This office is one of the most professional offices for orthodontists in the ATLANTA area. Every dentist I have been to has them at the top of their referral list. I had to switch orthodontists three times before coming to Kock/Evans upon the referral of my dentist and more personally - my mom who had great results. They are not the cheapest by any stretch of the imagination but you get what you pay for. After three years my bite is finally falling into place and Dr. Koch has worked magic. It is truly amazing to watch the transformation a true professional can bring about not to mention the fulfilled promise of being in and out in a year. I have referred my girlfriend and her brother to their practice and would do the same for anyone else. They are by far the best.
