National College of Natural Medicine is the oldest programmatically accredited naturopathic medical school in North America. NCNM began in the early 1950s, in response to the termination of the naturopathic program at Western States Chiropractic College. Members of the profession from Oregon, Washington and British Columbia planned the founding of the College and in May 1956, Charles Stone, W. Martin Bleything and Frank Spaulding executed the Articles of Incorporation of the National College of Naturopathic Medicine in Portland, Oregon. NCNM opened other satellite campus locations in Seattle and Kansas.
