Sioux Falls, a vibrant community in South Dakota, recently lost a cherished member, Brook Mitchell Van Gundy, aged 48, who passed away peacefully on January 18, 2026, following a courageous battle with ALS. Brook was not only a dedicated firefighter in Sioux Falls but a symbol of strength and determination, both in his professional and personal life.
Born on January 12, 1978, in Auburn, Nebraska, Brook’s journey led him to pursue his passion for building and public service. After graduating from Auburn High School, he attended Southeast Community College in Milford, NE, earning a degree in building construction. This skill served as a foundation for his later studies in fire protection at Southeast Community College in Lincoln, NE—a testament to his dedication to community safety.
In 2004, Brook embarked on his firefighting career in Sioux Falls, where he served with unwavering commitment until his retirement in 2023. His bravery, steady presence, and compassion earned him the respect of his colleagues and gratitude from families throughout the region. Brook was not just a firefighter; he was a beacon of hope, known for his willingness to help others long after the alarms had gone silent.
In April of 2012, Brook met Becky, the love of his life. Their bond was solidified in marriage on June 11, 2022. Just 11 months into their marriage, they were faced with Brook’s ALS diagnosis. Demonstrating the resilience that defined his life, Brook and Becky tackled this life-altering challenge with unity and courage, making the most of every day together.
South Dakota’s picturesque landscapes offered a comforting backdrop for Brook’s favorite pastime: fishing. Whether on the serene waters of the Missouri River or a tranquil lake, Brook found joy and solace with a fishing pole in hand. His patience and teaching ability made him a beloved fishing mentor to his nieces and nephews, and those shared moments became treasured family memories.
Brook’s story is also one of family love and loyalty. He leaves behind his wife, Becky, and a large extended family. His parents, Terry and Lorry Van Gundy of Auburn, Nebraska, his sisters, Staci (Joe) Edgington of Seward, Nebraska, and Hannah (Terry) Jones of Brownville, Nebraska, and his brother-in-law, Brian (Aly) Davis of Sioux Falls, remain grateful for the time shared with Brook. A loving uncle, Brook was cherished by his nieces and nephews, who will undoubtedly carry forward his legacy of kindness and courage.
His firehouse family, along with many dear friends and relatives, mourns the loss but celebrates the impact Brook had on countless lives. Preceded in death by his grandparents, Al and Esther Van Gundy, Don Kruger, and his mother-in-law, Annette Davis, Brook’s legacy endures in the memories of those he touched.
A celebration of Brook’s life will be held at First Christian Reformed Church in Sioux Falls on Friday, January 23, 2026, at 2:00 pm, following a visitation on Thursday at the same venue. In remembrance of Brook’s indelible contribution to community service and personal bravery, memorials can be made to Ava’s Hospice House or the Sioux Falls Firefighters Benevolent Foundation.
The Van Gundy family extends heartfelt gratitude to the nurses and staff at Ava’s Hospice House. Your compassion, strength, and empathy were a warm embrace for Brook and all who loved him during his final days.
South Dakota, with its community-centric spirit, is proud to remember Brook Mitchell Van Gundy—a testament to dedication and love for the places and people he so dearly cherished.
