Emeritus Professor, Northwestern Health Sciences University (NWHSU). I am currently “semi-retired” teaching in the chiropractic methods department on an Adjunct Faculty contract. I have served as a faculty clinician, seeing patients in the faculty clinic and the research clinic at NWHSU. Previously, I taught at the International College of Chiropractic which is now RMIT School of Chiropractic in Melborune , Australia . I am the founding editor of the peer-reviewed journal Chiropractic Technique and am on the editorial review board of Clinical Chiropractic . I have co-authored many papers, two textbooks, Chiropractic Technique Principles, and Mechanically Assisted Manipulation both by Mosby Publishing, and five ibooks , Cervical Manipulative Mechanics, Thoracic Manipulative Mechanics, Lumbar Manipulative Mechanics, Pelvic Manipulative Mechanics, and Part IV Board Review (https://itunes.apple.com/us/book/cervical-manipulative-mechanics/id655003943?ls=1#). I have also served as a consultant to Medicare and as a site team member for the CCE. I am a 1977 graduate of National College of Chiropractic. My professional passion is all things related to the art of chiropractic, i.e., the many forms of manipulative treatment, believing it is absolutely imperative that the profession continue to study manipulative procedures and the lesions they are intended to treat.
