Club Founder and Director, Dr. Gylton Da Matta launched  the Alliance YOSA Volleyball Club in 2012. He brings a deep knowledge and passion for youth volleyball to Northern Colorado and the Front Range. His volleyball development program blends elite, cutting-edge training and skills from Brazil, the United States, and other international powerhouses resulting in an experience unlike any other.    

Coach Da Matta has coached several Olympic and World Champion players, as well as All Americans at DI and DII collegiate levels.  If you want to be successful you need to practice smart, play like a champion and be a great student of the game. 

Coach Da Matta regularly invites accomplished international coaches to workshop with players at YOSA.  These coaches represent the elite levels of coaching, and they pride themselves on teaching volleyball at the most competitive levels.  

With YOSA Volleyball, the Northern Colorado now has a volleyball training center for excellence for committed athletes who share his love of the sport. 

We offer a volleyball training program for athletes who want to play volleyball systematically and with a life-long commitment. Our goal is to provide individuals at all levels an opportunity to develop in a safe, inclusive, and positive environment.   

Players will focus on acquiring and building skills, injury prevention, and overall health.  We will train those who want to play high-level club ball, and who plan to play in college.  Practices will require commitment, dedication and discipline, while also encouraging players to have a lot of fun.
