David Gordon Moore was born on September 6, 1946, in Tulsa, Oklahoma, to Gordon and Juanita Moore. He was one of four brothers, alongside Eddie, Jack Jr., and Tim. His father died before David was born, and he was lovingly raised by Jack Harris. David died peacefully on March 3, 2026, surrounded by family after courageously battling cancer.

A proud veteran, David served aboard the USS Okinawa during the Vietnam War and was honorably discharged at the rank of Personnelman Second Class (PN2). His service earned numerous commendations and reflected the integrity and commitment that marked his entire life. He did his duty the way he did everything, quietly, faithfully, and without seeking recognition.

Before he became a husband and father, he was a standout swimmer in high school, competing at the state level. It was during those years that he met his high school sweetheart, Sandra Jackson. They both graduated from the University of Tulsa, and what began there grew into nearly 60 years of marriage, partnership, and unwavering love. They were, in every sense, a team.

For nearly 40 years, David worked as a Mobile Products Manager in pneumatic and hydraulic equipment with Fluid Components and Berendsen Fluid Power. He was known for reliability, fairness, and the kind of calm, practical intelligence that keeps things running exactly as they should. He liked order. He liked things done right. There was always a to-do list, always a project underway, always a yard trimmed, a repair made, a detail attended to. Sitting still simply was not part of his wiring.

But his most important work was at home.

He was a hands-on father who coached and refereed soccer games and never missed a recital, game, or school presentation. He showed up, consistently, quietly, completely. He and Sandy were longtime season ticket holders for the Tulsa Roughnecks, TU Men's Basketball, and TU Football, and faithfully followed TU Women's Basketball, OU Women's Softball, and OU Football.

Reserved by nature, he possessed a perfectly timed, dry dad's humor and wit that became legendary in his household. His children grew up hearing classics like, "Does a one-legged duck swim in a circle?" "Does the Pope wear a funny hat?" and "Does Gladys Knight have Pips?" His delivery was understated; the laughter was not.

And then there was the whistle. It was ear-piercing, unmistakable, and carried across neighborhoods. When his children heard it, they knew exactly what it meant: time to come home. No phone calls. No chasing. Just that whistle, and everyone came running.

He loved family time above all. He loved his sailboat and the quiet peace of being on the water. In his later years, he loved Hallmark movies, without apology. He was a poet at heart, writing tender, heartfelt poems for his wife and children and recording unforgettable Christmas voicemail greetings that callers came to expect each year. Even in humor, there was love. Even in quiet, there was depth.

If fatherhood was his joy, grandfatherhood was his light. Known proudly as Granddad, he lit up around his grandchildren in a way that needed no words. He was their biggest fan, their steady encourager, and their quiet champion. He was endlessly proud of each of them.

David was preceded in death by his parents; his brother Eddie; and sister-in-law Missie.

He is survived by his wife of nearly 60 years, Sandra Kay Moore; his son Chris Moore; his son Greg Moore (Melissa) and their children Liam and Ivy; his daughter Amy Guzzy (Christian) and their children Ellison, Quincy, and Grey; and his brothers Jack Jr. (Carol) and Tim (Diane).

He lived a life marked not by volume, but by consistency. Not by spotlight, but by steadfastness. He worked hard, loved deeply, and showed up. And the echo of that unmistakable whistle, calling his family home, will carry on in the hearts of those who loved him most.

No services are planned at this time.
