Adrian Morales Castillo, 46, passed away on January 21, 2026, taking a piece of his family's heart with him.

Adrian, or "AC" as many knew him, was a kind, gentle, and generous person. He never met a stranger and was always willing to help anyone in need.

He accomplished so many great things in his short life. Adrian proudly served 15 years in the United States Air Force and was medically retired as a Master Sergeant (MSgt). He later worked overseas in Iraq and throughout the United States. In his journey he received a Masters degree in Aeronautical Project Management. Most recently, he had begun his dream job in Greenville, Texas, working as a Senior Quality Engineer, NDI.

Adrian loved spending time with his family, going fishing, working out, and—of course—cheering on his San Antonio Spurs and the Dallas Cowboys.

Adrian leaves behind his beautiful wife of 24 years, Yvette, and their two children, Jacinda and Justin. He is also survived by his mother, Aida Robledo; his father, Nick J. Castillo; and his stepmother, Theresa Castillo. He is also survived by his siblings, Nick M. Castillo III (Rosa), Clarissa Castillo, and Geneva Rios (Steven), as well as his many loving in-laws, and many nieces, nephews, and cousins.

He will be profoundly missed by all who knew him, and the world is now dimmer without Adrian in it.
