Lamberti, a sophomore who has suffered two serious knee injuries, was nominated by McDonogh boys' lacrosse coach Andy Hilgartner.
"This fall, as he was rehabbing, he helped to start a support group for other athletes that lost time in their sport from injuries," Hilgartner wrote in his nomination. "This player felt like there was a whole emotional side to missing out on playing that never really got addressed. So he thought getting kids together that were going through injuries or had already gone through an injury would be really beneficial."
Lamberti wasn't the only one who felt that way. Hilgartner estimated 25-30 students attended the group's first meeting, and he expects it to continue at McDonogh in the future.
During the award presentation, Hilgartner praised Lamberti as "a special kid" and highlighted his empathy.
"He's definitely put himself in the shoes of other athletes, both boys and girls, here at the school and tried to come up with a way to get them together to support each other," Hilgartner said.
Lamberti talked about what winning the award meant to him and how missing two seasons of lacrosse has shaped his viewpoint.
"I try to be the guy on the sidelines motivating my teammates," he said. "And now, starting this club ... is something I feel I can give back to people at my school going through the same situation."
With two more years left in high school, Lamberti hopes to potentially grow the club beyond McDonogh into a Baltimore area program.
"While he doesn't have varsity stats or a college commitment yet for lacrosse, he has been a good leader and role model in our program," Hilgartner wrote in his nomination.
