DENVER – Members of Safeway Rocky Mountain Federal Credit Union have given the CU's planned merger with DPS Credit Union a ringing endorsement with 88% approval in voting last month. The merger, which has been in the works for more than a year, would form the state's third largest CU. More than 2,200 votes were cast in a mail-back special election among SRMFCU members, said DPSCU whose members were not required to vote. The vote follows preliminary regulatory approval, which came in April. "We knew it was the smart thing to merge these two organizations," said SRMFCU CEO Darrick Weeks, whose organization primarily serves Safeway food store employees and families. The combined CU will have 56,000 members. DPSCU has a primary membership of employees of Denver Public Schools. The next step in the merger process is a naming and branding project, which will be headed up by Denver-based advertising agency Amelie Co. Final regulatory approval is expected next month.
