Who We Are
Dr. Gylton Da Matta
Club Founder and Director, Dr. Gylton Da Matta, launched the Alliance YOSA Volleyball Club in 2012. He brings knowledge and passion for our youth volleyball in Northern Colorado and the Front Range. Da Matta's volleyball expertise development program blends elite, cutting-edge training, humility, and performance skills from Brazil, the United States, and other international powerhouses such as Denmark, Italy & France, resulting in an experience unlike any other.
Coach Da Matta has coached several Olympic and World Champion players, as well as All-Americans at the DI and DII collegiate levels. If you want to be successful in sports as in life (have FAITH), you need to practice smart, play like a champion, and be a great student of the game.
Coach Da Matta consults, learns, and serves highly accomplished international coaches to provide love and enthusiasm for all YOSA players and families. When possible, he invites world-class coaches to work 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, Northern Colorado now has a volleyball training center for excellence for committed athletes who share their love of the sport and for our community. This year, 2025-2026, after hosting 5 elite volleyball people from the heart of the Rainforest in Manaus, our top teams have decided to do a service learning trip to Brazil, where we will bring love, compassion, and kindness to our brothers and sisters from Brazil. We will visit the cities of Florianopolis, Curitiba, Belo Horizonte, and/or Rio de Janeiro to become better citizens of the world and of our Lord's Kingdom of Love. This will be an educational and cultural trip where we will transform lives through sharing socks, clothes, and warm suits while we play volleyball with our partners in Brazil.
What We Offer: Opportunity to grow as people and as student-athletes
We offer a volleyball training program for athletes who want to play volleyball systematically and with a lifelong commitment. Our goal is to provide individuals at all levels an opportunity to develop themselves as people and as student-athletes in a safe, inclusive, respectful, diverse, and positive environment.
Players will focus on acquiring and building personal-social skills, injury prevention, and overall health-wellness. We will train those who want to play high-level club volleyball and who plan to play in college and/or for a lifetime. Practices will require commitment, attendance, dedication, and discipline, while also encouraging players to have a lot of fun.
