US ARMY NATIONAL GUARD VETERAN – BEXAR COUNTY SHERIFF OFICER
The family of Mr. Dennis Robert Casillas, a US Army National Guard Veteran, requests the presence and participation of the San Antonio Patriot Guard at the services, and the LEO supported procession, and graveside rendering of military honors of their loved one. We are honored to accept this invitation.
Dennis Robert Casillas, known to many simply as Dennis, was a man whose life was defined by service, strength, and a heart that never stopped giving. Born on November 11, 1963, in San Antonio, Texas, and passing away on July 31, 2026, in the same city he called home, Dennis lived 62 years marked by purpose, loyalty, and unwavering devotion to the people and causes he loved. He passed away following a cardiac event, leaving behind a legacy that will continue to echo in the lives of all who knew him.
Dennis was a proud son of San Antonio and a product of hard work, discipline, and determination. He attended John Jay High School, where the foundation of his character was already taking shape. Long before titles and rank, he understood the value of commitment and the power of showing up when it mattered most. That mindset would guide every chapter of his life and would become one of the reasons so many people trusted him, respected him, and looked to him as an example.
He began his professional journey as a helicopter mechanic for the National Guard, a role that reflected both his technical skill and his willingness to serve something greater than himself. From there, he joined the Bexar County Sheriff’s Office as a jailer, and his path continued to rise through dedication and excellence. He moved into patrol, where he served with grit and integrity, and over time he advanced through the ranks with his final position as Deputy Chief. He oversaw several important units, including the K-9-unit, SWAT, and patrol stations. Dennis did not simply hold positions. He earned trust, built teams, and led with a steady hand and a courageous spirit.
Those who worked beside him knew that Dennis was more than an officer. He was a leader who cared deeply about the people under his command and the community he served. He understood that true leadership is not about standing above others, but about standing with them. He was generous with his time, thoughtful in his decisions, and courageous in moments when courage was required most. He carried himself with the kind of presence that made others feel stronger, safer, and more capable. He set a standard that inspired others to rise higher.
Dennis also lived a life filled with passion and purpose beyond his career. He loved motorcycles, and that love became another way he built community and connection. He started a law enforcement member motorcycle club, bringing together others who shared his enthusiasm and his sense of brotherhood. He enjoyed organizing and participating in drives for children’s causes, using his energy and influence to lift young lives and support meaningful efforts. He also helped create and support benefits for his brothers in blue, always ready to stand beside those who stood beside him. He believed in action, in loyalty, and in showing love through service.
Dennis is survived by his beloved wife, Zulma Roa-Casillas, who shared in his life, his dreams, and his journey. He is also survived by his son, Dante Casillas, and his stepdaughters, Isa Roa and Gabriella Uribe. He leaves behind his sisters, Diana Casillas Morey and Debi Henderson, along with her husband, Michael Henderson. Each of them carries a part of his story, and each of them will continue to feel the impact of his love, his strength, and his steady presence.
To know Dennis was to know a man who gave freely, led boldly, and loved deeply. He was generous in spirit, courageous in action, and thoughtful in the way he treated people. He did not wait for the right moment to make a difference. He created those moments. He lived with intention, served with honor, and reminded everyone around him that a meaningful life is built one act of kindness, one brave decision, and one faithful step at a time. His legacy is not only what he accomplished, but how he made people feel while doing it.
Today, we honor Dennis Robert Casillas not only for the roles he held, but for the man he was. We remember his laughter, his leadership, his devotion, and his relentless commitment to others. We celebrate a life that stood tall in service and shined brightly in love. Though he is no longer here in body, the example he set remains powerful and alive. Dennis taught us that strength and kindness can live in the same heart, that courage can be quiet and steady, and that a life of service is a life that never truly ends.
