Meet the doctors

Roxanne Siegrist, DDS

Before she became a dentist, Dr. Siegrist was a wetland ecologist. Why does that matter? Because it gave her an understanding of how everything works together in any ecosystem – INCLUDING THE HUMAN BODY. She sees the teeth and jaws as the starting point for human health. She has been mentored by the most prominent functional dentists and airway orthodontists in the United States. She believes in using state of the art technology and “best in class” treatment techniques to support her holistic philosophy of primary dental care.

Christopher Rooney, DDS

Christopher C. Rooney, DDS is a lifelong resident of Kansas City, but spends regular time with us in Crested Butte where he has a second home. For over 20 years, Dr. Rooney has honed his craft, specializing in advanced oral surgery procedures, dental implants and reconstructive dentistry. He is among the nation’s top specialists, and serves as a Diplomat of the American Board of Oral Implantology — one of the top credentials an implant dentist can achieve.
