Mr. Gregory Mark Shelton

Mr. Gregory Mark Shelton, 74, was born March 26, 1952, in Vallejo, California, and passed away on October 31, 2026. He resided in Houston, Texas.

Gregory’s life reflected steady perseverance and purpose—qualities shaped early and carried forward with quiet strength. He graduated from Petaluma High School in Petaluma, CA, and went on to attend Prairie View A&M University in Prairie View, Texas, earning his Bachelor’s degree in 1977. His commitment to learning and self-improvement remained evident throughout his life, marked by a thoughtful, measured approach and a wisdom that others came to rely on.

Over the course of a long and respected career, Gregory brought more than 30 years of experience in diversified control systems in Electrical Engineering within the petrochemical industries, serving as a Senior Control Systems Specialist. Known for his work ethic and resilience, he approached complex challenges with care and discipline, and he offered the same steady consideration to colleagues that he extended to friends and family. Even in demanding environments, his kind-hearted nature and compassionate spirit were never far from view—and those closest to him also knew and cherished his understated sense of humor.

Outside of work, Gregory found enjoyment in reading and was a devoted science fiction fan, drawn to imagination and ideas that stretched beyond the ordinary.

Gregory’s faith and commitment to community were important anchors in his life. He was a member of Resurrection Metropolitan Community Church. He also maintained active professional engagement as a member of the Instrument Society of America (ISA), ASME, and IEEE—communities that reflected both his dedication to his field and his respect for shared knowledge and professional integrity.

He is survived by his sisters, Davnet Shelton and Claudia Shelton Smith, and his brother, Anton "Tony" Shelton.

Gregory will be remembered with deep respect and gratitude—for the steadiness of his presence, the generosity of his heart, the strength he showed through life’s demands, and the thoughtful wisdom he offered to others.

A memorial service will be held at a later date.
