No release that I can find yet, but the Cornell coaching staff page has been updated to confirm that Tim Crowley is the new assistant coach, working with HC Doug Derraugh and Associate HC Edith Racine. Crowley was the head coach at Division III Elmira College for the last six seasons, and the assistant coach for the Elmira men's program for four seasons prior to that. Crowley finished his career at Elmira with the most games won as a head coach, second highest winning %, and two DIII Frozen Four appearances.
Crowley replaces Dean Jackson as Cornell's assistant coach, mirroring Crowley replacing Jackson as Elmira's head coach in 2016.
Dean Jackson left Cornell to take a position as the Associate Director of Admissions and girls hockey coach at the Winchendon School in Massachusetts.
