Creating Beautiful Smiles

Here at Crossroads, we want you to have the best possible orthodontic experience. Dr. Mark Gregston, and the team are committed to delivering beautiful smiles in a comfortable and professional environment.

We strive every day to make sure that your experience is a pleasant one while we work together to get the very best smile.


What’s something you notice first about a person? Eyes, shoes, maybe even their clothes? Well, for us, and a whole bunch of other folks, it’s the smile. We think your smile can take you anywhere you want to go, and we pretty much spend all our time thinking about how to make that smile really stand out!

We have two convenient locations to serve you better. Come find us in Parker, or Castle Rock; that way, no matter where you are in the Denver Metro area, we’re never that far away.
