Mark D. Gregston, DDS, PC
Being an orthodontist is one of the greatest joys of my life. Having the opportunity to have a positive impact on the lives of so many people is extremely humbling. Every one of my patients has different needs but always the same goal: a beautiful, healthy and functional smile that they feel proud to share with the world. It is a pleasure to start the orthodontic journey with them and be by their side through the treatment process. I can’t describe the joy I share with the patient and their parents the day I take off their braces and they see their amazing new smile. I truly have the best job in the world.
I am committed to doing the best for my patients, to treating their orthodontic needs while assuring them that I am directly available for them throughout their treatment. I strive to create relationships that last long past their time in braces. Each patient is amazing; they are engaging and fascinating. I love learning about their interests and activities, and I love having the opportunity to develop friendships with them.
It is incredible to be allowed to watch a patient’s personality blossom as they see their smile change. It’s incredibly sad when a patient won’t smile during their first visit. Once they start to see the transformation and begin to smile with more confidence, I see their personality change. It’s a wonderful feeling.

I grew up in Independence, Missouri, and I now call Parker my home. My lovely wife, Sandi, and I have three gorgeous daughters. When I’m not caring for my patients, I’m usually with my family; they are my focus and my joy. However, I also enjoy watching movies and sports, golfing, and playing softball and volleyball. I am personally committed to being the best husband and father possible.
I love living in Colorado. Every day on my drive to work, I get to see the beautiful sunrise come over the mountains. I am constantly amazed at the beauty of this state. When I was stationed at the Air Force Academy in Colorado Springs, I knew this was where I wanted to raise my family.
Commitment to the Community
I feel that it is essential for everyone to give back to the community by donating time and helping others improve their lives. Professionally, I donate time and dental expertise to Smile Again, Smiles Change Lives, and Dental Lifeline Network. Our practice sponsors local baseball teams, Boy Scouts, and elementary schools. My family is also active with the Denver Dumb Friends League, a local animal rescue shelter, and we foster animals through the organization.
