Meet Our Team
Dr. Nathan Kronemeyer
Doctor of Chiropractic
Dr. Kronemeyer grew up in Michigan’s lower peninsula and earned his degree in Exercise Science from the University of North Dakota in 2005. Before pursuing chiropractic care, he spent several years coaching swimming and managing restaurants - experiences that strengthened his appreciation for teamwork, balance, and helping others reach their potential.
He went on to earn his Doctor of Chiropractic degree from Palmer College of Chiropractic in Davenport, Iowa, where he served as a teaching assistant in the rehabilitation department, worked in a low-income outpatient clinic, and helped assess students’ clinical readiness. After graduating in 2015, Dr. K began his career in a rural South Dakota community before making Colorado his home.
Since taking over Thrive Chiropractic in 2018, Dr. K has shaped the practice into a welcoming, family-oriented space focused on supporting the health and vitality of the whole person. He is especially dedicated to helping people of all ages and activity levels move with ease, recover naturally, and maintain lasting wellness through individualized, evidence-based care.
Outside the clinic, Dr. K enjoys writing, cooking, and staying active in the community. He and his wife, Regina are proud to call Brighton home.
