Duncan has spent nearly thirty years treating members of the public. This equates to approximately forty thousand osteopathic treatments given. This breadth of clinical experience has allowed him to help patients of all ages in their recovery process. Before setting up his own osteopath practices he spent thirteen years working at a variety of clinics. These varied from small one-man band clinics where Duncan was Receptionist, Osteopath, and chief bottle washer, to much larger multidisciplinary centres working alongside Physios, Chiropractors, Acupuncturists, Homeopaths and many others.
