Mario was known for his ability to create imaginative stories and hilarious jokes. He had a unique talent for making people laugh and holding engaging conversations, which endeared him to all who had the pleasure of knowing him. He enjoyed playing the guitar and spending time with his daughters.
Mario was preceded in death by his parents, Thomas and Maria Luisa Ontiveros, and his brothers Jorge, Alejandro, and Thomas.
He is survived by his daughters, Raeleen Raygoza and Eileen Reyna, as well as his nephew, Omar Ontiveros, who lovingly cared for him during the last years of his life.
Rest in peace, dear Mario Ontiveros. Your memory will live on in the hearts of those who knew you at your best.
