Tennyson was 15 when his father told him the family was moving from Minnesota to Pleasanton, Calif. At the time, Tennyson thought his hockey career was over. He had no idea it was just beginning.

Shortly after making the move, Tennyson joined the Jr. Sharks program that was started by then-Sharks owner George Gund in 1991. Seven years later, on Dec. 18, 2014, Tennyson became the first product of that program to score an NHL goal when he scored in a 4-3 victory against the Edmonton Oilers.

An undrafted free agent who played junior hockey in the North American Hockey League and United States Hockey League, Tennyson took the college route to the NHL via Western Michigan.

Nearly two years before the defenseman scored his first NHL goal, he got his first NHL point on April 1, 2013 against the Vancouver Canucks.

Tennyson spent the majority of his first three years in pro hockey playing for Worcester of the American Hockey League, and he led Worcester defensemen in goals (five), assists (22) and points (27) during the 2012-13 season.
