Experienced Colorado Native

Get to Know Dr. Nathan Schaffner

Following twenty-two years of practicing in the small eastern Colorado town of Yuma and six years as the on-site dentist for the employees of Woodward, Inc., Dr. Schaffner established Schaffner Family Dental in January, 2017 in beautiful Fort Collins. He feels honored to have had most of his Woodward patients follow him to his new private practice. The practice continues to grow through word-of-mouth referrals.

As owner of the only dental practice in Yuma, Colorado, Dr. Schaffner gained valuable experience in all aspects of general dentistry. He enjoys treating patients of all ages. In addition to his private practice, Dr. Schaffner served as the consulting/treating dentist at long-term care facilities in northeastern Colorado. Although most patient dental care is completed in our office, Dr. Schaffner feels blessed to practice in a community with outstanding dental specialists to whom he refers for specialty dental care as needed.

Outside of dentistry, Dr. Schaffner most enjoys spending time with his wife (Liz), his three daughters (Brielle, BrookLynn and Janie) and his son-in-law (Matt). When time allows, he likes mountain get-aways and other travel. He is actively involved in Valley Christian Church of Loveland where he serves as an Elder.
Dr. Schaffner's professional organizations include: - American Dental Association - Colorado Dental Association - Larimer County Dental Society
