Ten employees of the Dubuque Packing Company pooled $5 each, in combination with a loan for $123.20 from the Amalgamated Meat Cutters Local Number 150, to begin operations. From these humble beginnings, Dupaco Community Credit Union membership has grown to more than 57,000 members. Obviously, the belief by our founders that there is value in being part of a not-for-profit, member-owned financial cooperative has really caught on. As we have grown, so has our ability to provide an expanded range of cost-effective financial services designed to help members get ahead while meeting their lifetime financial needs.
