Tierney had the longest tenure, 19 seasons, of the four head coaches of the Cal State Hayward Pioneers football program. After the dissolution of the football program following the 1993 season, Tierney remained at Cal State Hayward, working as a professor of kinesiology until 2001 and then serving as head coach of the men's and women's golf teams.

Tierney died on September 15, 2012, from complications following brain surgery.
