A Growing, Passionate Community

If you have never been here, you’ll find Thronton to be a fresh and friendly city. Relative to most towns, Thornton is quite young, having been founded in 1953 when a developer decided to build homes north of Denver. Since then, Thornton’s welcoming environment has helped it grow exponentially. As of this year, Thornton has more than 130,000 residents that call it home!

Thornton is a diverse community with a strong commitment to quality of life and environmental issues. The city is just 10 miles north of downtown Denver, so it offers all the advantages of a big city with the comfortable, community feeling of a small town. It is also only a short ways away from Boulder and the University of Colorado campus.

With its quality-of-life focus, Thornton has aggressively pursued recreation programs, with nearly 1,000 acres of land developed or designated for public parks. The numerous lighted tennis courts, athletic fields, indoor and outdoor swimming pools, recreation centers, and gymnasiums offer recreation opportunities for people of all ages and activity levels.​

We have been very fortunate, and are indeed a bit humbled, to have received nearly every accolade and award possible here in Thornton, CO for our work, including being named the #1 Orthodontist in Thornton by Colorado Parent Magazine and included in 5280’s (Denver’s premier magazine) list of top providers for five years in a row!

This year, the Colorado Community Newspapers named Colorado Orthodontics the “Best of the Best” among our community’s orthodontists!  We are so honored that the people of Thornton consider us to be Thornton’s best orthodontist!

We promise to continue to work hard in providing exceptional orthodontic care to the Thornton community and helping the residents of our awesome city with all their orthodontic needs. You can visit our homepage for more information on some of the awards we have won as a practice.

Dr. David Mershon and Dr. Baumgartner (we call her Dr. “K” for Krystal) serve as our primary doctors for this location. They are supported by our awesome team.
