Benefiting cancer research since 1977
Every August since the summer of 1977, the Killebrew-Thompson Memorial in Sun Valley, Idaho has gathered hundreds of individuals including celebrities, members of Congress, professional athletes, corporate sponsors, participants and volunteers around one common goal: FIND A CURE FOR CANCER.
The tournament was founded by Hall of Famer Harmon Killebrew and Congressman Ralph Harding in memory of the Minnesota Twins shortstop, Danny Thompson who died of leukemia at the young age of 29. Through their hard work and the dedication of their supporters, the KTM is now considered one of the leading cancer research fundraisers of its kind.
