His continued contributions advanced innovation beyond his formal career.
Grady's greatest pride and deepest love was his family. With quiet conviction and steadfast example, Grady's lifelong purpose was to serve Christ faithfully and lead his family toward salvation. He was a devoted husband, father and grandfather who was engaged in the everyday moments as well as the milestones.

He generously offered unwavering support, guidance and love to his children, their spouses, his grandchildren, as well as his siblings.
He treasured his friendships which were rooted in faith, laughter, loyalty and common history.
Grady loved to travel with friends and family, especially spending time in the mountains, and on trips to Colorado, and found joy in outdoor activities such as water and snow skiing. A passionate sports fan, he faithfully supported the Dallas Cowboys and his beloved TCU Horned Frogs. He gave generously of his time to his community, serving on the Lovejoy Independent School District school board, coaching little league sports, attending church youth trips, where he was known for encouraging teamwork, discipline, and character.
