Adam Balin, MD


Adam is an MD who has practiced Family Medicine at the Dean Clinic (now SSM Health, Dean Medical Group) in Oregon, WI since 1989. Over the years there he has served on myriad committees, task forces and leadership positions, including Chair of Family Medicine, Primary Care Regional Medical Director, and the Dean Clinic Board of Directors as well as on the Dean Foundation Board of Directors. He is also faculty at the UW Madison School of Medicine and Public Health and teaches residents at the Northeast Family Medical Center, where he got to know Jeff Patterson much better. He ultimately went to his first HHPF (then HHP) October conference in 2011. Adam was profoundly impressed and moved by that conference, which completely changed his perspective of how to care for patients with chronic musculoskeletal pain. He went to the very next Honduras service learning trip for 2 weeks with Jeff,  Mary, Chet, and many other dedicated instructors and volunteers. He returned to practice as a convert to prolotherapy and what it could offer patients. Shortly afterward Jeff asked him to serve on the HHP Board of Directors, specifically because of his large system governance and operations experience, and with the intent of moving HHPF to a new level of organization that would continue to grow and improve patient care well after Jeff, Mary and the rest of us were no longer there to do it. Currently serving on both the HHPF BOD and the new IART interim BOD, Adam continues to help move the vision and mission of both organizations to realize Jeff's dream of a world where chronic pain is better understood and where reliable, effective treatment is accessible to all.
