Riley grew up in Palo Alto, California. He played college basketball at Whitworth University under Jim Hayford.^[2] While starring for the Pirates, Riley was a three-time All-Northwest Conference first-team selection and finished his career ranked fourth all-time in points with 1,664 along with making four NCAA Division III men's basketball tournament appearances, including two Sweet Sixteens and an Elite Eight.^[1]

When Hayford accepted the head coaching position at Eastern Washington, Riley followed as a graduate assistant coach.
