Born in San Bernardino, California, Terri grew up in Hesperia, where she graduated from Hesperia High School, and was an active member of the dance and drill team. While attending Victor Valley College, she worked as a cake decorator at Vons Grocery Store, where she met the love of her life, Dennis. Together, they built a beautiful life filled with love, joy, and a deep bond that lasted for over 27 years.

Family was the heart and soul of Terri's life. She devoted herself to raising her children, nurturing their passions, and supporting them through every milestone. She took great joy in watching her children and grandson thrive in their activities, especially cherishing the special moments she spent with her beloved grandson, Sage. Terri’s love for her family also extended to her three dogs, whom she adored and spoiled as part of her family.

In her spare time, Terri enjoyed traveling, sightseeing, shopping, watching football, and driving her Corvette. She was known for her kind heart, sense of humor, smile, and the light she brought to everyone around her.

Although Terri's physical presence is no longer with us, her spirit will continue to inspire and live on in the hearts of all who loved her. Her memory will forever be a blessing, and her light will continue to shine brightly in Heaven and in our lives.
