Here's what our patients have to say:

  • "My daughter is 8 years old and saw Dr. Klein for her first initial visit. She was very nervous about her appointment and everyone on staff made her feel welcomed and reassured. She left the office so excited she told everyone we spoke with that night about her appointment. She cannot wait to go back and see everyone! Excellent service! Highly recommend this office to anyone!" ~ Kelli M.
  • "I was happy with my choice of Klein Orthodontics. The office is very nice and clean. I never had a long wait time and the appointments were quick without feeling rushed. My teeth turned out well and the treatment time was shorter than I expected. I would recommend these providers." ~ Tiphani M.
  • "Thank you to Klein Orthodontics for outstanding service yesterday with my daughter Reagan! She had to have her braces tightened and have two brackets replaced. Your staff is so sweet and reassuring to nervous youngsters -- they always make Reagan feel so at ease. Thank you!" ~ Suzie S.
  • "It was a great experience. My teeth went from bad and was crooked to a nice beautiful smile. They are very gentle with your teeth. I LOVE this orthodontist. They’re very good. Thank you, Klein Orthodontics." ~ Hayleigh S.
  • "We had a great experience with Klein Orthodontics. The staff is really friendly and helpful. One receptionist spent a considerable amount of time on the phone trying to determine what our insurance would cover. Dr. Brian Klein explained everything in depth and made our daughter feel at ease. We would highly recommend Klein Orthodontics!" ~ Kim H.
