Oliver attended college at Heale’s Business School in San Jose, Calif. and the University of Colorado in Boulder, Colo., where Oliver and Mary lived for over 30 years before returning to their native South Dakota in 2000, where Oliver served as a letter carrier for the Rapid City Post Office until he retired in 2010.
