Sean McNamara is the Director of Team Tendy Lacrosse, a Kansas City–based goalie training program dedicated to helping athletes reach their full potential—on the field and in life. A former collegiate starting goalie and team captain at Monroe Community College and Randolph-Macon College, Sean brings both high-level playing experience and a deep passion for developing the most impactful position in the game.

With over 20 years of coaching experience across youth, high school, and collegiate lacrosse—including NCAA Division II and III programs—Sean is known for his intense, detail-driven coaching style and commitment to continual growth. His training environments emphasize technical mastery, mental toughness, accountability, and high-rep competition.

McNamara credits several coaches and resources that have shaped his development as a goalie coach, including Jeff Schwartz (St. John Fisher College), GoalieSmith, and countless hours studying educational content through YouTube, the IMLCA, and other coaching resources. However, he believes the greatest growth has come through ongoing dialogue—conversations during games and practices that allow him to learn directly from the goalies he coaches. As the position continues to evolve, Sean believes coaching begins with an open mind, asking good questions, and continually learning alongside the athletes he serves.
