Dr. Harp Koehler treats the whole body using Motion Palpation, nutritional counseling, and soft tissue techniques. She is a Certified Kinesio Taping Practitioner and is certified in the Graston® and Webster techniques, and she uses muscle testing to diagnose everything from sports injuries to food sensitivities. She treats back and neck pain, headaches, and extremity issues with manual adjustments, cranial work, activator, and drop-piece adjustments. Her conservative, whole-body approach, along with the time she spends with each patient, reflects her compassion and genuine investment in their well-being.
Dr. Harp Koehler previously practiced chiropractic in Hastings, MN before her and her husband, Jake, moved to Elk River. They enjoy raising their two boys, Kellen and Levi, in the community that her husband grew up in. In her spare time, she enjoys spending time with her family and friends, working out, attending concerts and sporting events, and loves to golf as much as she can.
