In 1961, Dr. Zelm and his wife, Joann, opened the clinic in an era when chiropractic was not considered "mainstream". Yet, clinical excellence and altruism grew a thriving practice. Dr. Craig Brue joined ZCC in the 70s and later retired in the 90's. In 1987, Dr. Zelm was joined by his son, the late Dr. Mark Zelm. He served as president of the corporation and helped grow it to the two locations. In 1990, the second clinic in McFarland, was created and led by the Zelms' daughter, Dr. Ann Metzler. The family business continues to operate under the vision and practice philosophies of Drs. Alan and Mark, who were outstanding doctors, exemplary leaders, and sincerely cared for their patient population. Welcome to Zelm Chiropractic!
