Sawyer Dowden - Assistant Coach

Sawyer Dowden has been playing volleyball since the summer of 2021. Sawyer has attended many volleyball clinics in the Northern Colorado area including Windsor, Berthoud, and Greeley. This season Sawyer is a volunteer coach at Alliance YOSA where I intend to support and do my volleyball academic internship with Dr. Da Matta. Sawyer will also be a supporting manager for Alliance YOSA volleyball camps and clinics, the Volley Teens, Masters Volleyball, and the Volleyball International Program (V.I.P.). Sawyer is a native of Colorado and played volleyball at the University of Northern Colorado on the university's men's volleyball club team. Currently, he is taking a year off of school to work and get even more engrossed in the world and sport of volleyball. "Volleyball is something I am very passionate about and I love Alliance YOSA," said Sawyer.
