Dr. Mark Betsill

Dr. Mark Betsill is a dedicated chiropractor serving patients in Gresham with more than a decade of experience helping individuals move better, feel better, and return to the activities they enjoy most. He earned his undergraduate degree in Physical Education and Health from Boise State University, where his interest in health and human performance first began to take shape.

After experiencing firsthand how chiropractic care helped him recover from an upper back injury that was affecting his golf game, Dr. Betsill discovered the path he wanted to pursue. He went on to attend Western States Chiropractic College in Portland, earning his Doctor of Chiropractic degree in 2007.

Dr. Betsill focuses on helping patients recover from neck and back pain, sports injuries, postural stress, auto accident injuries, and workplace-related conditions. He uses gentle, effective techniques including manual adjustments, the Activator Method, and drop-table adjustments to address spinal misalignment and extremity dysfunction. He also has a special clinical interest in neck and lower back disc herniations, often combining chiropractic adjustments with computerized mechanical traction to improve pain relief, mobility, and function.

While many patients first visit because of pain, Dr. Betsill is passionate about helping them move beyond symptom relief. His goal is to help people improve functional movement, maintain spinal health, and support long-term wellness. He treats patients of all ages—including infants, children, teens, athletes, and pregnant women—and believes chiropractic care can play an important role in addressing not only spinal concerns, but also shoulder, elbow, wrist, hand, hip, knee, ankle, and foot discomfort.

Shortly before graduating in 2007, Dr. Betsill faced a personal health challenge that deeply shaped his philosophy of care. After multiple emergency room visits for dizziness, syncope, and chest pain, he began looking beyond symptoms alone. Through that experience, he came to better understand the effects of physical, chemical, and emotional stress on the body. By combining chiropractic care, massage, exercise, and proper nutrition, he restored his own health—an experience that continues to influence the way he cares for patients today.

Originally from northern Nevada and southern Idaho, Dr. Betsill grew up playing sports, with golf becoming a lifelong favorite. He also enjoys hunting, fishing, and spending time outdoors. Today, he and his wife and two sons enjoy life in the Pacific Northwest. When he’s not in the office, you’ll often find him on the course with the men’s club at Gresham Golf Course or staying active and fit with his family.
