The Founders
Northern Peak Chiropractic was founded by Drs. Bethany and Devon McMullen. The name Northern Peak was inspired by their roots. Dr. Devon is from the Great White North of Canada and Dr. Bethany spent her childhood conquering the “Peaks” of the beautiful Black Hills. Their journeys would cross paths at Chiropractic school where they not only fell in love with chiropractic, but with each other. Their next crossroad was finding a town to call home.
The first time they came to Watertown they knew it was the one, from the growing community to the friendly people, Watertown felt like home for the both of them. Drs. Bethany and Devon are honored to serve the community of Watertown and its surrounding areas. They look forward to becoming a part of the community and supporting it for years to come.
