Attack Cancer is a fun and interactive way for athletes to make an impact both on and off the field. Athletes from all sports around the country are pledging their performance this season to assist the HEADstrong Foundation and families affected by cancer.

Meet Ken Clausen, National Director of Attack Cancer

A 2010 graduate of the University of Virginia, Clausen was a four-time All-American with the Cavaliers, including three First Team selections. In his senior season, he won the Schmeisser Cup as the top defenseman and was a finalist for the Tewaarton Award. The 5th overall selection in the 2010 Major League Lacrosse draft by the Denver Outlaws, Clausen spent six seasons in the MLL, capturing a title with the Outlaws in 2014.

Clausen is no stranger to the HEADstrong Foundation, as he co-founded the foundation’s largest third-party fundraising campaign, Lacrosse Mustache Madness, in the fall of 2009 while a senior at Virginia. Clausen, who shared a position, a number and a birthday with HEADstrong founder Nicholas Colleluori, wanted to do something to support Nick’s vision while involving his teammates and fellow student-athletes and since its inception, the campaign has raised over two million dollars and involved tens of thousands of collegiate lacrosse players across the country.

In addition to his playing experience, Clausen also has extensive experience on the sidelines as both a high school and professional coach. In seven seasons as a high school defensive coordinator with two teams in Colorado, Clausen captured one state championship and coached numerous All-Conference, All-State and All-American selections. He parlayed that experience into a season as the defensive coordinator with the Denver Outlaws before spending the last two seasons as the defensive coordinator with Atlas LC of the Premier Lacrosse League.
