Phoenix Baptist Hospital: May 1981 - July 1987. During that time I was a member of BPA, Biological Photographic Association which is now BCA, BioCommunications Association, Inc. The organization was founded in 193. I have their commemorative medals from their 25th Anniversary in 1955 and their 50th Anniversary, 1980. I became a member starting in 1981.
