About Us

There are a lot of important things to consider when you're researching orthodontists, but the most important decision you'll make is the team you choose for braces or clear aligners. We understand that, and that's why we've worked hard to create an amazing team that we're really proud of. In fact, every member of the Harwell and Cook team gets rave reviews from our patients, and that's what drives us.

You can find out more about Dr. Harwell, Dr. Cook, and our amazing team members on this page. But the best way to check us out, is to schedule a complimentary initial exam and get to know us in person.
