Robert Gentner

Robert made his home in San Antonio, Texas, where he built a life rooted in quiet strength, devotion, and service. Robert honorably served his country in the United States Army for 27 years, rising to the distinguished rank of Sergeant Major. His military career reflected not only his dedication to duty, but also his deep commitment to those he led and served alongside. As a combat veteran of Vietnam, his courage and sacrifice were recognized with the Purple Heart and the Bronze Star with Valor.

Beyond his service to his country, Robert was deeply devoted to his faith and community. He was an active member of the Knights of Columbus, serving as Grand Knight, 4th Degree, and Deputy District. He was also a respected local businessman for over 30 years, known for his integrity, hard work, and the meaningful connections he built throughout his life.

He is lovingly remembered by his wife, Okhui Gentner, whose partnership and care were at the heart of his life.
