Gregory Allen Hoellwarth, a cherished member of his community, passed away at the age of 67 on May 24, 2025, in his home after a courageous fight against cancer. He will be remembered not only for his resilience but also for his vibrant spirit and diverse interests that endeared him to family and friends alike.
Born on July 5, 1957, in Solano County, California, Greg was the son of Beverly and Robert Hoellwarth MD. He grew up in Vallejo, where he began to cultivate his eclectic passions. After spending two years studying Electrical Engineering at California State University, Sacramento, he transitioned into a successful career as a computer programmer. His professional journey included roles at the Mark Larwood Company in Sacramento and Quantum in Napa, where he worked until 2020.
Greg’s love for birdwatching was a shared passion with his father, leading him to compile an impressive list of bird species throughout his life. His enthusiasm for the outdoors extended to cycling; he actively participated in cycling clubs, volunteered for road races, and became known for his dedication to watching the Tour de France each July, often dressed in his cycling gear.
Beyond cycling, Greg enjoyed Frisbee Golf and, in later years, Bocce. His involvement in model railroading was significant, as he not only participated in clubs but also possessed detailed knowledge of locomotives and historic trains. His travels with his wife, Gayle Keane, often featured iconic rail journeys, reflecting his passion for trains.
One of Greg’s most meaningful contributions was his work with Canine Companions. Over a span of 25 years, he and Gayle were instrumental in raising more than 300 puppies for the organization’s service training program. This dedication showcased his commitment to improving the lives of others through assistance dogs.
A dedicated member of the Napa Valley Unitarian Universalist Church, Greg served on the church board twice. He often engaged in thoughtful discussions about spirituality, despite identifying as an atheist. His open-mindedness and curiosity about existence made him a beloved figure within the community.
Greg leaves behind his wife, Gayle; three siblings—Tina Korabiak, Carla Little, and Chris Hoellwarth; numerous nieces, nephews, and in-laws; as well as his adored Labrador Retrievers, Zambra and Etta.
In honor of his legacy, the family requests that, in lieu of flowers, contributions be made to organizations that promote and support the free practice of truth in journalism. Greg’s impact on his community and his unwavering kindness will be deeply missed.
