Marshall Steven Shore, beloved husband, father, son, brother, and friend passed away on December 22, 2025, at the age of 38, from acute staphylococcal sepsis. His loss is deeply felt by all who knew him. 

Marshall is survived by his devoted wife, Rebecca Shore; his cherished children Evan (5) and Eliana (2); parents, Larry Shore and Clare Castiglia; sister Jennifer Walsh; and brother, Daniel Shore. 

He is remembered not only for his unwavering devotion as a father and spouse, but also for the way he pushed the boundaries of his family's patience, always striving to make every family experience vibrant and memorable, and lived life to the fullest. 

A proud graduate of the University of New Mexico Business School, Marshall built a successful career for 19 years at Nusenda Credit Union, where he was respected for his professional acumen, integrity, and mentorship. Marshall's commitment to his community was deep; he was an active volunteer for Big Brothers, Big Sisters of New Mexico, St. Luke Lutheran Church, the World Affairs Council, NAIOP Developing Leaders, and the Lobo Club. 

Marshall loved hiking, camping, snowboarding, cooking for his family, tackling home renovation projects, attending Popejoy shows, and engaging in spirited philosophical debates with his wife. His happiest moments were spent with his children and wife cheering for the Lobos, and exploring new mountains and beaches. 

In lieu of flowers, please donate to St. Luke Lutheran Church, or a Child's Garden Preschool.
