Robert “Bob” Sierra, 65, of Loveland, Colorado, went home to heaven on December 7, 2025. He was born on May 7, 1960 to Robert Sierra and Maria Sierra. He is proceeded in death by his father, Robert Sierra, brother, Alvin Sierra, and his baby sister, Samantha Sierra.

He is survived by his mother, Maria Sierra who was his queen. His siblings, Steve Sierra, Chris Sierra, Mike Crespin, Theresa Sierra, Sandy Sierra. He had 5 children, Ted Pacheco, Amanda Rios, Robert Sierra Rios, Maria Rios (his boss), and Angel Rios. He had 17 grandchildren, Kambrya Pacheco, Siena Pacheco, Anzley Pacheco, Lorenzo Leon, Carlos Cisneroz, Israel Cisneroz, Jaliyah Rios, Diondre Rios, LaNyiah Rios, A’leenah Rios, A’Yanah Rios, Izaiah Grado, Izaac Grado, Dominic Grado, Noah Grado, Mario Rodriguez Jr. He also had 7 great-grandchildren, Ari’yanah, Izzy, Ali, Aria, Aj, A’ziel, A’ziya

He loved his grandchildren and was always quick to give them loving lectures on life. He was so creative and enjoyed making crafts with them, using anything he could find around the house. Turning simple objects into special memories. They always enjoyed movies together and he had every candy you could want in his stash. He loved telling stories, making silly jokes, and eating good food.

He had a unique personality and unforgettable sense of humor. His passions were music, cooking, and watching old movies. During this season it was always, A Christmas Story. Throughout the years his all-time favorite show was Gunsmoke. He was a talented cook who could make any dish. I always said, he could make something amazing out of nothing. If you ever asked him what he wanted, it was always a pot of beans and homemade tortillas. He was best known for his love for hot chile, he always had the best homemade hot salsa, and if he didn’t have that he had a jalapeno in his pocket. He never left home without a pair of his all black sunglasses.

Bob will be remembered for his kindness, his creativity, his humor, and his ability to make everyone around him laugh and feel loved. That love will live on in the generations he leaves behind, and the countless memories his family holds close forever.

 It’s see you later, not goodbye, as he always said.

May he rest in peace
