Dave served his country with honor as a Sergeant E5 in the United States Marine Corps (1963-1968). His military career included two tours as a Scout Dog Handler in the Vietnam War, for which he received the Presidential Unit Citation, National Defense Service Medal, Vietnam Service Medal (1 star), and Vietnam Campaign Medal.

Beyond his military service, Dave found joy as a member of St. John's Catholic men's group, where he made close friends that helped him to grow in his Catholic faith.

He loved the rodeo, cleaning stalls, and camping at Caddo Lake with the whole family. Watching Ellen Grace and Kascey Marie barrel race always brought a smile to his face.
