Jack Semler played at
Vermont for four seasons during the short period when it was a
Division II program. After graduating he eventually rose to become the head coach at
Princeton. After four unproductive seasons with the Tigers he accepted the post to be the first head coach for
Maine's ice hockey program. Semler posted winning records in both seasons that Maine played in Division II and helped the Black Bears to a good showing in their first year at the Division I level. The program slumped a bit beginning in
1981–82, and though improvement was shown in his final season, Semler left the college ranks in
1984. Semler would continue coaching but wouldn't return to the
NCAA until 2006 when he became an assistant for
Skidmore College. After stops at both
Assumption College and
Nichols College Semler ended up at
Rice Memorial High School. ==Head coaching record==
