Yosa Boys & Girls Volleyball Training

Dear Parents, Athletes and Friends,

We have a new volleyball training program for athletes who want to play volleyball systematically and with a life-long commitment. 

We will be training athletes with talent who also want to play club and in the future play volleyball in college.  Practices will require commitment, dedication and discipline.  I have coached several Olympic level, World Champions and All American players.  If you want to be successful you need to practice smart, play like a champion and be a great student of the game.

Our Purpose & Mission

​Focusing on athlete’s health and promoting injury prevention training strategies, the primary goal of Alliance YOSA is to provide high-quality teaching, training, and coaching to committed student-athletes in an educationally sound environment that ultimately will cooperate with the individual skills development of its participants.

I have coached more than 4 Gold medalists in the Olympics and more than 9 world champions volleyball players at the U18, U21 and senior level teams.  I have also trained and taught volleyball for all American and players who are actually thriving at DI, DII and professionally in the United States, Brazil, Germany, Spain, Japan, Switzerland and Sweden.  I have recently taken the Huskers Volleyball to their International Tour in Brazil and I am also consulting and teaching both at the Nebraska Coaching Certification as well as the Brazilian Coaching Education programs.
