Reyna shared some photographs from his childhood where he can be seen posing with his brother with a caption that read: "In honor of what would be my dear big brother Jack’s 25th birthday, we’re celebrating his life by donating to the foundation that cared for our family and will forever hold a special place in our hearts. For over 28 years, Making Headway has dedicated itself passionately to the mission of providing Care, Comfort, & a Cure to families impacted by a childhood brain or spinal cord tumor. The foundation remains by our side and continues to provide invaluable support to many other families who are navigating challenging times. We ask that you join us in making a donation to Making Headway because any contribution will serve as a meaningful tribute to Jack’s spirit and the enduring impact he had on all of us. The link will be in my bio to donate!"
