We are Dušan Sidor Sr. and Dušan Sidor Jr. a father & son goalie coaching team, both former professional goaltenders with an unmatched passion for the position.
With over 30 years in the making, our training methods have been developed, refined, and proven through real results, helping goalies reach the NHL, the Olympics, and elite leagues around the world. Our approach not only maximizes potential but also emphasizes longevity and injury prevention.
We call it the “Tendy Method”: a philosophy built around the demands of the modern goaltender. Everything we do is designed to develop goalies, not just athletes. Our system is founded on four pillars of success: Goalie specific off-ice training, focused on-ice training, detailed analysis and recovery of the body and mind.

Dušan Sidor Sr. discovered his passion for goaltending in 1961 at the age of five, when he strapped pads on for the first time and got hooked for life. He played most of his career in former Czechoslovakia (CSSR), and after the fall of the Iron Curtain he moved west to pursue coaching goalies and to share his deep understanding of the position.
As an active goalie, career highlights include winning the CSSR Championship, representing Czechoslovaka alongside legends like Peter Šťastný, and capturing a Slovak national championship title. His coaching achievements are just as impressive: an Italian Serie A title, both Swiss NLA and NLB championships, a Swiss Cup victory, mentoring several national team goaltenders and the early development of two NHL starting goalies.
When Dušan Sr. began his coaching career, goalie coaches were virtually unheard of, making him a true pioneer in the field. With over 40 years of experience coaching goaltenders at all levels and countless hours spent studying and refining the craft, Dušan Sidor Sr. is now regarded as one of the premier goalie coaches in the world. His methods are well known and used around the world.

Dušan Sidor Jr. was destined to follow in his father’s footsteps as it was clear from a young age that goaltending ran in his blood. His hockey journey began in Europe before moving to North America to play junior and DI college hockey and later continued in Europe where he played professionally. Playing career highlights include winning two Italian championships, the French Championship and the Slovak Tatry Cup.
At age 16 while still actively playing, Dušan Jr. began coaching alongside Dušan Sr. during the off-season, gaining hands-on coaching experience that would shape his future. He transitioned into full-time coaching immediately after his playing career. Coaching highlights include earning silver and bronze medals in the Slovak Extraliga, a Dusan Pasek trophy for finishing in first place and working with the Slovak NTDP. Dusan Jr. is currently working as a goalie coach in the Slovak Extraliga.
Having worked with goalie coaches from diverse backgrounds throughout his playing career, Dušan Jr. developed a broad understanding of international coaching philosophies and brings a unique and balanced approach to modern goaltender development.
