The physicians of Pulmonary Medicine Associates note with sadness the passing of their colleague Donald Van Dyken M.D. A passionate caregiver and gifted diagnostician, Dr. Van Dyken was a popular family practice physician, past President of both the Washoe County Medical Society and the Nevada Academy of Family Physicians, and a past chief of Chief of Staff at St. Mary's Hospital. Pulmonary Medicine Associates extends our deepest sympathies to Dr. Van Dyken's family.
