Years Elite Sport

Ken Sio spent over 13 years competing at the highest level of professional rugby league. Through that journey, he learned that success is not built on talent alone. It is built on discipline, consistency, accountability and showing up when things get hard.
After football, Ken created DOS ATHLETE to help athletes, parents, young people and everyday people become stronger physically, mentally and emotionally.
