In late September, the Academy of Integrative Health and Medicine (AIHM) sent out a notice to its list to celebrate the 80th birthday of perhaps its most honored male elder, Bill Manahan, MD. Manahan’s story dates back to a founding membership meeting of a predecessor to the AIHM, the American Holistic Medical Association (AHMA), 40 years ago. One of Manahan’s most powerful areas of impact is an AIHM priority: sewing interprofessional respect. He’s worked to pry open the MD guild – which proved necessary even in the MDs’ “holistic” form. Manahan has been a mentor to countless practitioners and other functionaries in the holistic health and integrative medicine movement, including me. I thought his birthday was a good excuse to re-connect and explore a couple pieces of his rich history in the field – specifically the inter-professional work and the remarkable Minnesota group he has managed for 40 years.
