Grzelcyk is a native of Charlestown, Massachusetts, and was drafted by his hometown Bruins in the third round (85th overall) of the 2012 NHL Entry Draft. Apparently, Matt isn't the only Grzelcyk that is employed by the Boston Bruins franchise.
Matt's father and older brother, both named John, work at TD Garden on the maintenance crew known as the "bull gang," responsible for scraping the ice during TV timeouts and converting the arena from hockey to basketball and back.
