After taking this past season off as he recovered from a battle with throat cancer, Brendan Flaherty on Sunday resigned as Duluth Marshall boys hockey coach.
In his resignation letter to the school's athletic director, Kevin Snyder, Flaherty wrote: "I did not make this decision easily or happily. I had hoped to be ready to coach the Hilltoppers when our players begin practice in November, and still do. But I can't guarantee the pace of my recovery."
Flaherty led the Hilltoppers for 20-plus seasons, seven of which resulted in state tournament appearances. Marshall reached three straight Class A title games from 2006-08, finishing runner-up each time.
In his absence, Bill Owens, previously an assistant under Flaherty, coached the Hilltoppers on an interim basis in 2018-19.
Flaherty was diagnosed with the throat cancer last April and had hoped to return to the Marshall bench. In November, he was declared cancer-free.
In his letter, Flaherty wrote, "I have been honored to devote my life to hockey."
