The Bennion Lambourne Orthodontic team is an amazing group of experienced staff members. Some of them have been with the practice since the day we opened our doors! You’ll see the same friendly and familiar faces at your visits and receive care from people you know and trust.

Our team is well-trained and passionate about the care we provide. We love helping people we care about to get the beautiful, lasting smiles they deserve!

The staff is here to assist you at every visit, whether you have a question about your insurance, need to find a convenient appointment time, or just want to chat a bit. We’re warm, fun, and caring, and truly love what we do.

Our Office

We have two convenient locations in Billings: Billings West End and Billings Heights. We also offer locations in Cody and Sheridan, WY.  Each is a modern, stand-alone building with plenty of parking. They feature comfortable reception areas, game rooms, and state-of-the-art clinical areas.

Our office is a clean, safe, and secure environment. It’s also welcoming and filled with laughter and smiles from our patients, doctors, and team members. We provide fun games and contests to keep patients and their families engaged throughout the treatment.

Our Approach to Orthodontic Treatment

Dr. Bennion, Dr. Lambourne, and Dr. Ledingham create customized treatment plans for each patient. They use digital X-rays for better results and less radiation, as well as 3D X-rays for more accurate treatment planning. Your orthodontic plan will involve leading-edge techniques, such as clear aligners and braces, self-ligating braces, and laser teeth whitening. We also offer in-office laser soft tissue procedures.

We believe everyone deserves an incredible smile and do everything possible to make that happen. In addition to complimentary initial consultations and recall exams, we accept most insurance plans and participate in SCRIPTS for Billings Christian Schools. We also require no down payment and provide flexible, no-interest payment plans. Many discounts are also available, including family discounts and pay-in-full discounts.
