Meet the Dental Providers

Roxanne Siegrist, DDS, MS

Dr. Siegrist is a passionate and dynamic dentist. She has found that the possibilities for a dentist are endless. Throughout the day she plays many roles: surgeon, mechanic, architect, artist, scientist, detective, and coach.

Dr. Siegrist graduated with a B.A. in Biological Sciences from the University of Chicago in a curriculum that encouraged multi-disciplinary and analytical thinking. Then she earned her Master’s Degree in Science, working in the wetlands of Louisiana, looking at metabolic patterns in microbial communities. This research sparked an interest in the human microbiome and the view that the mouth is just a really cool miniature wetland. Dr. Siegrist got her dental degree at the State University of New York, Stony Brook, a small dental school with intensive clinical training.

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. In her freetime, Polina is learning lightwire orthodontic appliance fabrication, a highly artistic and technical enterprise comparable to fine jewelry creation. Polina loves hiking, mountain biking, skiing, and her labrador, Max.

Carrie lives in Farmington, New Mexico, but works closely with Dr. Siegrist especially in treating patients from the four corners region.

Meet Sprocket!

Clinical Support Pup

Sprocket is our most popular team member. After his owner died, he was brought to the Aztec Animal Shelter, in New Mexico. As an 11 pound shih tzu mix, he held his own with the rough and wild reservation dogs of the four corners. After 6 months, he was brought to the area by Gunnison Underdog Rescue. Dr. Siegrist went to meet him and immediately knew that he was the sidekick she needed to treat children and phobic patients. Sprocket is the perfect size to cuddle in your lap. He loves to be held on his back and will close his eyes like a babydoll when you lay him back. The children and adults absolutely love him.

Roxanne Siegrist, DDS, MS

Dr. Siegrist is a passionate and dynamic dentist. She has found that the possibilities for a dentist are endless. Throughout the day she plays many roles: surgeon, mechanic, architect, artist, scientist, detective, and coach.
Dr. Siegrist graduated with a B.A. in Biological Sciences from the University of Chicago in a curriculum that encouraged multi-disciplinary and analytical thinking. Then she earned her Master’s Degree in Science, working in the wetlands of Louisiana, looking at metabolic patterns in microbial communities. This research sparked an interest in the human microbiome and the view that the mouth is just a really cool miniature wetland. Dr. Siegrist got her dental degree at the State University of New York, Stony Brook, a small dental school with intensive clinical training.
After dental school, Dr. Siegrist worked for the National Health Service Corps in rural Arkansas. As a solo dentist in a profoundly underserved area with a 500 person waiting list, Dr. Siegrist quickly gained experience, especially in pediatric dentistry and oral surgery.
Dr. Siegrist has been practicing general dentistry in Crested Butte for ten years. She has transformed a rural general practice into a thriving center of alternative dentistry. Dr. Siegrist loves every aspect of general dentistry, but she is particularly committed to helping children grow their jaws and airways to their greatest potential and rehabilitating adults to mitigate the effects of poor growth and retractive orthodontics. She is always asking how the mouth can impact the rest of the body including the nervous system, the airway, and systemic health. Dr. Siegrist is an incessant learner, dedicated to continuing education and participating in diverse professional study clubs. 

Dr. Siegrist lives a lifestyle of alternative health. She is a home-birthing, kombucha-brewing, long-term breastfeeding, fascia-transfiguring mountain mama. She has three rambunctious and brilliant sons, Jack, Charlie, and Teddy, and two rescue dogs, a big dog, Hoss, and a little dog, Sprocket. She sees motherhood and her profession in health care as synergistic– being a mother drives the endless learning to make lives better and being a healthcare provider drives the knowledge to support her children’s best health. 

The natural beauty of Crested Butte is a source of constant joy for Dr. Siegrist. She loves to experience nature in solitude and enjoys hiking and Nordic skiing. Her favorite thing is being in the woods after fresh snowfall. She plays old time string instruments. Her latest musical project is learning mystical modal tunes on a fretless, goat-skin, clawhammer banjo.
