But one thing has remained constant for the young forward over the past four seasons: his time in Prince Albert as a member of the Raiders.
"I came in as a 15-year-old after the WHL Draft and I didn't really know much about the city or team to be honest," recalled Kelly. "Now it's become my second home. My billets and I are so close and I've made so many great friends in Prince Albert that I'll be coming back to this place long after I'm done playing hockey."
Kelly shared that he couldn't have scripted a better final year in Prince Albert. The Raiders have been one of the most dominant teams in the Canadian Hockey League all season, including a 19-game win streak back in the fall, and finished tops in the WHL with a stunning record of 54-10-2-2.
"We had a great start to the season and went on a really nice win streak early on," he said. "From there it just kind of snowballed towards our end goal of first being regular season champs then following that up in the playoffs by becoming league champs."
The Raiders punched their ticket to the Memorial Cup with a massive 3-2 overtime win in Game 7 of the WHL finals against the Vancouver Giants on Monday night that saw Kelly contribute a pair of assists in regulation as well as helping to cause some chaos in front of the opposition's net on the game winning goal in extra time.
The 20-year-old forward was especially happy with the opportunity to share Monday's win with the home crowd in Prince Albert who he believes helped push the Raiders to their first Western Hockey League championship since 1985.
"Securing home ice this post-season was big for us," said Kelly. "You dream about playing in a Game 7 as a kid playing mini-sticks with your friends so it was incredible to be a part of that win. Being on the ice for the OT winner with the fans going crazy is something that I'll never forget."
Kelly made sure to also credit working with the Ottawa Senators development coaches and staff as a big reason for his continued growth on and off the ice, in particular the many resources, tips and feedback that he's had access to over the past two seasons. And the Senators have definitely noticed.
"Parker has made huge strides. He's already really mature and he's a guy that just gets it," said Sens Player Development Coach Shean Donovan. "Right now, he's the guy in our organization that's won this season and that's important. He put in a lot of work last summer, his skating and hands have improved, so he just keeps getting better."
