More on the SDAHA Hall of Fame

The South Dakota Amateur Hockey Association Hall of Fame (HOF) was founded in 2022 to establish a memorial to those who have developed the sport of hockey in South Dakota.

The SDAHA Hall of Fame exists in order to honor and memorialize individuals who have brought special distinction to the game of hockey and those who made outstanding contributions to the development and advancement of hockey anywhere in the State of South Dakota and also to collect, research, preserve, exhibit and promote objects, images and other historical materials connected with the game at all levels.

The Hall of Fame will be comprised of members from four different influential groups within the sport of hockey.  They include players, coaches, officials and builders (executives).

The inagural class of the hall was inducted in 2023.
