They are great people. The staff is awesome and very friendly. You can count on a warm welcome from the staff. Dr.Langford is a very nice person with a great since of humor. He has a very bright smile to everybody. He is very nice and try's not to hurt we he is putting on the braces or what ever he is doing for you. He also has 2 locations in Knoxville and in Seymour, so which ever one is the most convenient for you you can go to that location. All the staff and Dr.Langford are all very nice, so if you need an orthodontist I would highly recommend Dr.Langford.
