In July, the Seattle Kraken appointed Campbell as an assistant coach, establishing her as the first female full-time assistant coach in NHL history. Campbell’s landmark achievement was celebrated during the Kraken's season opener against the St. Louis Blues at Climate Pledge Arena, where she received a round of applause as she joined the bench.

Reflecting on the significant moment, Campbell acknowledged the profound impact of her appointment. "The moment leading up to the game and stepping on the bench... I'm really going to try to honor what it is, because I know, and I definitely understand that the magnitude and the importance of this moment is really important for our game," she said. Despite the Kraken's narrow 3-2 loss to the Blues, the focus remained on Campbell's groundbreaking role. Head coach Dan Bylsma emphasized the positive aspect, stating, "Jessica being a female coach in the NHL for the first time, it's great for her and it's great for the game."

While Campbell described the day as "normal" in terms of her work and routine, she is acutely aware of her role's significance. "I never want to diminish the things that I'm doing because I'm so focused on the task at hand," she noted. "But I also know that being focused on the task at hand has allowed me to get to this moment and is going to continue. So, I have to stay focused on what matters most, which is the guys and the team and the success that we want to have."

Campbell, 32, previously made history in the American Hockey League (AHL) when Bylsma hired her as an assistant coach for the Coachella Valley Firebirds in 2022. Her tenure with the Firebirds was marked by success, including reaching the AHL's Calder Cup Finals over the past two seasons. Prior to this, she served as an assistant coach and skills coach for the Nürnberg Ice Tigers in Germany's top professional men's league during the 2021-22 season and also assisted the German national team at the 2022 world championships.

Looking to the future, Campbell expressed hope that her achievement would pave the way for others. "Hopefully somebody else will have a door held open for them versus them having to push it open and find ways to unlock it," she said. She highlighted the importance of diversity in achieving success, stating, "Anytime you have different people in the room, you get different and good outcomes; you get unique outcomes. You get problems solved in a different way and I think that's how you get ahead in life and in sport."

Campbell's journey in hockey includes an impressive playing career from 2010-14 at Cornell University, where she was the team captain in her senior year. She also played professionally in Canada and Sweden and was named MVP of the 2010 under-18 world championships, where she led Canada to a gold medal victory.
