Leopold Lockhart grew up in Concord, Masachussets where he started playing hockey at age six. For that whole first season, hockey was just something kinda cool Leo did on weekends and after school a couple of days a week. He had some natural talent, but he didn't spend much time away from the rink thinking about the sport or practicing skills. At age seven however, Leo's mom left and that's when Leo really started spending a lot of time on hockey. He used the sport as a coping mechanism. By age eight, he was completely obsessed, spending most of his time at the rink or practicing stick work in the garage. His skills began to impove exponentially. In the early days, Leo made friends with a kid on his team named Elijah. Elijah and Leo played hockey together from age six, all the way through middle school, but Elijah quit before high school so he'd have more time for other extracurriculars and Leo continued to play, putting him on the path to the SMJHL and eventually the SHL.
