Who We Are

Our History

This orthodontic practice was launched by Dr. Daniel McQuinn. He was an excellent provider who eventually transferred the care of his patients to Dr. Greg Olsen, who renamed it Olsen Orthodontics.

For more than a decade, Dr. Olsen and the team at Olsen Orthodontics provided great care through the Damon System and with Invisalign®.  Dr. Olsen passed the care and responsibility of his patients and practice to Dr. Aaron McDonough in June 2017.

Although we're renaming the office Granite Peak Orthodontics, we will carry on the tradition of great care and exceptional service that patients and local dentists and dental specialists have come to expect.  

Granite Peak will continue to be the only Damon System office in Missoula. We also offer Invisalign at no additional cost. Our practice uses progressive concepts to ensure we always practice in the modern era. We have had an incredible beginning, but we wholeheartedly believe the best is yet to come.

Why Granite Peak

Granite Peak is the tallest peak in the great state of Montana. For us, Granite Peak is a reminder never to stop exploring the world around us. We are an orthodontic office, but our roots are in the mountains and rivers of this beautiful place. Our mission is to give every adventurous soul a great smile to match. 

Our Team

Dr. Aaron wants to have the best-trained orthodontic team in the state. He’s passionate about learning and believes a better-educated team will deliver better care.

That’s why we keep training every day. It’s part of our DNA. We bring in the best local minds, search out the best national practices, and keep looking for better ways to do our work, care for our patients, and connect with our community.

Our training is not just about teeth. Although we do train every month to the standards of the American Board of Orthodontics, we also learn about the world around us, the biology of the human body, the psychology of kids and teens, and how to listen and communicate effectively.
