About Us
Alan and Trisha Kroll built The Diff in the Fall of 2010. They established this non-profit organization with the sole purpose of trying to make a difference in the lives of young athletes. Alan and Trisha have had a heart for young people and sports for as long as they can remember. Alan was an All-American swimmer in high school and a collegiate swimmer at the University of Kansas. Following his college career, he landed an assistant coaching position for the swim team at the University of Kansas (KU)! Now with 3 sons and two daughters, Alan is on the sidelines cheering his wife and kids on. Trisha was an All-State volleyball player in high school and played Division I volleyball as a setter for the University of Kansas. She has been coaching volleyball since 1998. She started coaching at the club level while in Kansas. After moving to Colorado, she became a high school coach at Holy Family in 2002 and continued her career there for 10 years. In 2012, Trisha started The Diff VBC. In the club’s first year the 14 Black team finished 3rd in the region and qualified for Junior Nationals in the USA Division. In 2013-2014 (The Club’s second year of existence), the 15 Black team finished 4th in the Region and qualified for Junior Nationals in the National Division. In 2014-2015 The Diff 16 Black got 3rd at Nationals. In the years to follow The Diff had many more victories! In 2022 Trisha’s daughter was facing her 5th brain surgery and Alan and Trisha knew that unfortunately it was time end this chapter of running a club volleyball program. In 2022 Trisha closed The Diff VBC and now she has more time to pour into her family and any extra time she spends pouring into the lives of young athletes through camps/clinics, lessons and her Mind of a Champion Program (www.mindofachampiontraining.com ). Trisha works with teams and individuals and continues to make a difference in the lives of athletes all over the state of Colorado and beyond! Her coaching is innovative and inspiring. She has an app for her Mind of Champion Training Organization and she elevates athletes’ skill in the gym by using film evaluation to move them quickly down the path of mastery.
