Embarking on his professional career, Vande Sompel was reassigned following training camp with the New York Islanders to AHL affiliate, the Bridgeport Sound Tigers, to begin the 2017–18 season.

[5] As a rookie he also represented Bridgeport at the 2018 AHL All-Star Classic, scoring three goals, tied for most out of any player.
