Dentist,     Carolyn Kupka, DMD    


Boulder cosmetic dentist Dr. Carolyn Kupka has successfully practiced the art of dentistry, serving Boulder, Denver-area patients, for over 30 years. She established her dental practice in Boulder following graduation from the University of Kentucky Dental School, Lexington, KY, in 1977. In keeping with her commitment to excellence, Dr. Kupka is a graduate of the Las Vegas Institute of Advanced Dental Studies (LVI) -- a premier postgraduate training facility for Neuromuscular and Cosmetic Dentistry. LVI’s state-of-the-art clinical courses include hands-on patient treatment, not just observation.

Dr. Kupka continues to stay current in dental innovations through ongoing coursework at LVI, ICCMO, IACA, AACD, AGD, DOCS and local dental courses. Dr. Kupka adamantly believes the future of health and dentistry can only be found through extensive research, study and experience; she is extremely committed to ongoing education for both herself and the Team. “You don’t know what you don’t know” as Dr. Bill Dickerson, founder and CEO of LVI, often quips. So learn what you don’t know!! And implement it for the well-being of our patients. Dr. Kupka lives near the foothills of Boulder where she raises and enjoys American Quarter Horses, bred for performance in reining and working cow horse. Although she has no cows, for several years you could find bison in the front pasture. Dr. Kupka shares the household with felines Arnie and Frankie, adopted from the Boulder County Humane Society. Like many residents of Colorado, Dr. Kupka is an outdoor enthusiast, often combining her love of the outdoors, horses and friends while riding in the beauty of the Colorado mountains. She has shown performance horses in reining with the American Quarter Horse Association (AQHA) as well as the National Reining Horse Association (NRHA). Her "career" in working cow horse (NRCHA) was shortlived but exciting. With a breeding program, many of her foals have become national champions. Other interests include travel, reading, photography, scuba diving, movies and music.

Over the years, community service has played an ongoing role with time spent volunteering at the Colorado Therapeutic Riding Center and the Boulder County Dental Aid Association where she also served on the Board. She has consistently supported the auctions and activities of such groups as the Boulder County Humane Society, Boulder County Safehouse and Community Action Program, church programs for Guatemalan Dental Aid and Russian Aid Society, Zonta, the YWCA, the Wild Animal Sanctuary in Keenesburg, CO, as well as donations of riding horses to a local children’s home.

Dr. Kupka has mentored many dental interns in the office, several of whom went on to CU Dental School, Hygiene and Dental Assisting Schools. Dr. Kupka participated in the Daily Camera Care Givers Makeover, treating the dental needs of the featured women  with great results and appreciative winners.
