Every gastrointestinal pathologist in the United States and Canada received an invitation to attend the first organizational meeting, held during the 1979 IAP meeting. At that meeting, the establishment of a society was approved, and four subcommittees were formed to deal with membership, finances, bylaws, and educational activities. During the next year, all organizational functions were completed, and at the 1980 IAP meeting, the organization was officially established, by-laws were approved, the first officers elected, the first dues collected, and the first educational program was offered.
