About Foster Orthodontics (formerly Willham & Foster Orthodontics)

Reviews highlight long-term relationships with the practice, including patients who followed treatment from initial spacers or braces all the way through retainers years later. Dr. Austin Foster is frequently described as attentive and skilled, often speaking directly to child patients about their treatment rather than only to parents.

I love the people and most especially their services. Thank you!🫶
Love love this office!!! Dr Foster and his staff are the best!!! Highly recommend them and will be recommending them to all that we know!!! Thank you for our son's treatment, he had a great experience and tells his friends they need to go to Dr Foster's!!! 👍❤️
Environment made me uncomfortable. The dentist would refuse to work with me because they couldn’t sell me on things I did not need every time I went, they would look at me and actively avoid me. I would be sitting there until The office was almost closed. Spend your time and your money elsewhere
Dr Foster is the absolute best around! He is so kind and caring and does what’s best for each patient! I am so thankful for him and his whole team! They are all so amazing!
Wonderful doctor and office. He's very informative and walks you through the process. He didn't charge us for putting a spacer in my child's teeth, twice. The fact he's willing to take time out of his day and not charge people, shows he really cares about his work and clients. They made my kid feel comforted even during stressful moments. I will highly recommend to anyone!
