Dr. Gregg Lindsey

My interest in orthodontics began as a 14-year-old orthodontic patient.  I was embarrassed and self conscious about my smile.  I was amazed how my smile was transformed by my orthodontist.  It gave me increased self confidence and self esteem.  One of the joys of being an orthodontist is seeing those same changes happen in other people's lives.  Initially, I studied accounting in college and worked as a CPA for 5 years.  Eventually I determined to return and study dentistry, and orthodontics in particular.  I have not regretted that decision.  I love what I do and I enjoy my association with patients, in particular those who are pre teens and teenagers.  I enjoy seeing them over their treatment time and seeing the changes inside and out that occur as a result of their transforming smiles.  I am committed to partnering with every patient to achieve a beautiful and functional smile that can last a lifetime

Dr. Mark Gregston

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 people and be by their side through the treatment process. I can’t describe the joy I share with patients 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.
