With two brothers, a sister, a brother-in-law, and a nephew, all having served in the U.S. Army, it has always been important to me to support our military. Seeing Gary play and perform for the troops with his Lt. Dan Band has been a blessing and a miracle because it’s what he loves to do, and it’s so pure and joyful. I have great respect for what he’s doing. Our family is proud to have been able to support him over these many years in his mission, and so proud to see how that mission evolved into the Gary Sinise Foundation.
