Meet the Dental Providers

Roxanne Siegrist, DDS, MS

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.

Polina Pikhulia, EDDA

Restorative Artist

Polina is from Chelyabinsk, Russia, a town in the Ural Mountains made famous by the 2013 meteor. Polina’s aptitude in science and visual arts directed her to dental training at an early age. She attended dental school in Russia for four years before falling in love and relocating to the US. Polina is fabulously artistic, meticulous, and passionate about dentistry. She reveres the form and function of every individual tooth and her tooth sculpting skills are unsurpassed.

Christopher Rooney, DDS

Dr. Rooney 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 surgical 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. With an exacting personality, Dr. Rooney scrupulously plans every facet of each implant case.
