As a devoted father, he cherished moments spent with his daughter Samantha, nurturing her with love and wisdom.

He is survived by his beloved mother Betty Tesoro Skinner, his wife Lisa, his daughter Samantha, and grandson Anthony. His siblings, Christine Tesoro Curtis, Theresa Mary Feeley, Michele Tesoro, Bette L. Gordon, and Joyce (Jaye) Tesoro, will also carry his memory in their hearts.
