Dr. Chris Keirnan


Dr. Chris Keirnan was born and raised in Florida. While running a successful bicycle shop after graduating from FSU, he had a low back injury after jumping off a 12-foot wall on his bicycle.

Seeking Chiropractic care, he learned how the brain controls all of the parts of the body, including his digestive organs and sinuses. After this experience helped him not only feel better but also improve digestion and reduce allergy symptoms, he decided he needed to become a Chiropractor and share this miracle with everybody.

While acquiring his Doctor of Chiropractic degree from Life University in Atlanta, he was introduced to the technique Chiropractic BioPhysics. Right away he was drawn to the science and precision of this technique. He practiced for 3 years in Atlanta and almost 5 years in Asheville, NC before finding his way west to settle in Denver in 2014.

In his spare time, he races his car in autocross and enjoys cycling, working out, and hiking for fun and fitness.

Karen Rylander

Certified Nutrition Consultant

Karen Rylander, Certified Nutrition Consultant, grew up in Houston, TX and moved to Colorado where she earned a B.A. in anthropology from the University of Colorado-Boulder in 2000.

After removing processed, inflammatory foods and adopting a primal-type diet in 2009, she felt great health improvements including more energy, fewer skin problems, better sleep, and more balanced moods.

This experience inspired her to learn more about nutrition and she attended Bauman College in Boulder, CO to receive her certification as a nutrition consultant in 2011.

She has been working with clients since then, helping them find greater health and vitality through a real-food, ancestral approach to health. Karen is also a trained chef and loves to Crossfit.

Beyond the gym, she enjoys walking, skiing, reading, hiking, and leisurely biking.
