Like many elite referees, Bob Corb started his water polo journey in the pool. A club player at Northeastern University and then the University of Massachusetts, Corb transitioned to the whistle not long after his playing days concluded. He founded the New England Water Polo Referee's Association before migrating west to California in search of the best available competition to officiate. Corb would advance through the ranks, reaching the USA FINA list in the early '90s. He took on some of the top assignments around the globe, including two Pan American Games, three FINA World League Super Finals, three Junior Pan American Championships and a World University Games.

A mainstay on the domestic front, Corb was a longtime collegiate official and part of the crew at the first NCAA Women's Water Polo Championship in 2001. He served as head referee at Junior Olympics and Senior Men's Outdoor National Championships and was the NCAA National Coordinator of Officials from 2009 to 2019.

Away from wearing the whites, Corb coached a variety of clubs in Southern California, earning medals in Junior Olympics play, and assisted in sports psychology for the USA Women's National Team. At the administrative level, in addition to his work with the NCAA, Corb served as the head of the Southern California Aquatics Federation, helped launch the national women's collegiate championship and held a variety of roles within USA Water Polo governance committees. In 2018 Corb received the Paragon Award from the International Swimming Hall of Fame for his contributions to water polo. He remains active in the game today as the Big West Conference Coordinator of Officials.
