Gary Sinise is a happy man with a supportive family and an impressive career. Aside from his wife, Moira, of more than four decades and three adult children, the actor also has another family.

It is the Gary Sinise Foundation that he treats as a family, and has all of his children contribute to the charity.

Gary founded the veterans' service organization in 2011, which offers a variety of programs, services, and events for wounded veterans of the military. It is a nonprofit organization that mainly focuses on providing and constructing mortgage-free, specially adapted smart homes for severely wounded veterans.

The official site confirms that the Gary Sinise Foundation has raised $282 million for wounded veterans, first responders, and their families from 2011 to 2021.

As of April 26, 2022, the foundation moved its headquarters from Los Angeles, California, to Franklin, Tennessee.

Gary Sinise actively participates in the foundations' campaigns and regularly posts about his works on his social media handles. The 9/11 attacks deeply impacted the actor; thus, he started supporting the military.
