Since 2011, the Gary Sinise Foundation has provided a medley of programs and services to military veterans and their families. Millions of dollars and several custom homes later, the nonprofit continues to offer ways to address the needs of veterans, even those not physically visible. But the organization also looks after the families mourning a fallen soldier. Spouses lose a partner and children lose a parent. During the holidays, emotions of every type can be raw and bitter. To address these emotional needs, the organization runs its Snowball Express, which kicked off this week. The Snowball Express would usually fly military families to Disney, to provide some pure, uninterrupted fun, along with special shoutouts. When the pandemic hit and with precautions still at play, it changed its routine; now, it virtually connects families with celebrities sharing special notes to them - and that’s only part of what’s promised. All aboard the Snowball Express! Gary Sinise has been giving to those in the military since the '70s / U.S. National Archives & DVIDS Gary Sinise grew up in a family of military veterans and his efforts to give to others started back in 1970, decades before his foundation. Even beyond its formation, Sinise has personally traveled around the world to support active military members. The Snowball Express actually predates the Gary Sinise Foundation, beginning in 2006 and partnering with the nonprofit in 2017.
