The modern day youth sports environment has taken the enjoyment out of athletics for our children. Currently, 70% of kids drop out of organized sports by the age of 13, which has given rise to a generation of overweight, unhealthy young adults. There is a solution. John O’Sullivan shares the secrets of the coaches and parents who have not only raised elite athletes, but have done so by creating an environment that promotes positive core values and teaches life lessons instead of focusing on wins and losses, scholarships, and professional aspirations. 


 John O’Sullivan has complied the latest research into the physical, social and psychological impacts of early vs late sport specialization, so that parents and coaches can lead their athletes down the right path when it comes to youth sports.  Is It Wise to Specialize will provide you with practical guidance and cut through all the red tape, so your child and you can enjoy youth sports.

“I am currently residing in Bend, Oregon, but I grew up back in New York. I did my undergraduate degree at Fordham University and my master’s degree at the University of Vermont. My love of sport came as a child, then as a college and a professional athlete. Then I got into coaching. I coach university, and I’ve coached kid sports for a long time. I founded Changing the Game Project in 2012, wherein I thought I could hopefully make a bigger difference for more people by bringing some of the latest research in education, psychology, youth development, and sociology and other things around the sporting experience. I really felt that sports had shifted away from being centered on the experience of the athlete or the child, and it was more about the business of sport or the people running sport. My goal was to give parents and coaches great information so that they could create a better environment for kids, and we’d have a far lower dropout rate and a far more successful sporting environment for all involved, whether you were an ultra competitive athlete pursuing the Olympics, or someone who just wants to run around and hang out with their friends, which is fantastic as well.” – John O’Sullivan
