Frey served as international president of GEAPS from 1972-73. In recognition of his volunteer leadership service to GEAPS and the grain handling industry, he was bestowed the honors of GEAPS Industry Leader in 1973 and GEAPS Member of Distinction in 1974 and 1985. Frey was truly dedicated to GEAPS and helping industry operations professionals.
