Key Discussion Points & Insights

1. Early Inspiration and First Connections to Veterans

(01:28 – 09:11)

• Family Ties to Service:
  Gary’s support for veterans started in the late ‘70s and early ‘80s, influenced by his wife’s brothers—both Vietnam veterans—and his wife’s brother-in-law, a combat medic. Their stories opened his eyes to the often overlooked sacrifices of Vietnam veterans.

  • "They started talking to me quite a bit about what it was like to serve in Vietnam and then come home. ...They really had a profound impact on me back in the ‘70s and early ‘80s..." — Gary Sinise (01:38)

• From Oblivion to Advocacy:
  As a high schooler, Sinise was unaware of the turmoil of the Vietnam War. Meeting these veterans compelled him to get involved, initially by supporting local veterans in Chicago years before his acting breakout.

• The “Tracers” Play:
  Sinise spearheaded the production of the play Tracers, written and originally performed by Vietnam vets, at Chicago’s Steppenwolf Theater. The production offered free weekly performances to veterans, helping them see their stories reflected and honored on stage.

  • "Tuesday nights were free for veterans, and all of a sudden, we would have a couple hundred veterans in the audience..." — Gary Sinise (08:48)

3. The Lt. Dan Band and USO Tours

(11:33 – 17:15)

  The band emerged from USO tours after 9/11, as Sinise sought to uplift troops abroad with music and direct engagement — transitioning from handshake tours to band performances worldwide.

  • “The band came out of USO work I started doing after September 11th…I would just go on handshake tours…then [I asked] ‘What about letting me go on a band tour?’” — Gary Sinise (11:33, 13:10)

4. Founding and Mission of the Gary Sinise Foundation

(17:15 – 22:30)

• From Individual Support to Broad Impact:
  Sinise initially volunteered with countless nonprofits but realized forming the Gary Sinise Foundation in 2011 would amplify his ability to help.

(34:33 – 40:55)
