01/13/1957 - 02/12/2026
Brian Francis Spiers passed away unexpectedly on February 12, 2026, at the age of 69 while walking his dog among the vineyards at his home in Geyserville, California. Born and raised in San Francisco's foggy Outer Sunset, Brian attended St. Gabriel's and Archbishop Riordan High School, where he would later become Chairman of the Board and honored with the Chaminade Award.
Brian built a wonderful life with his beloved wife, Debi. The two would have celebrated their 40th wedding anniversary this year. He cherished his children, Erin, Sean, and Ryan, and Joey, his son-in-law, was truly a son to him. In recent years, he reveled in his role as "Gunka" to his adored grandchildren, Sophie and Lucy. He was preceded in death by his mother, Patsy, and niece, Theresa. He is survived by his father, Sean, and his brothers Michael (Jack), John (Bernadette), Steve (Peter), and Dan (Máire); and Áine (Chris, deceased), who was like a sister to him, along with many nieces and nephews.
Brian took great joy in traveling with his family. Together, they spent summers at their Tahoe family cabin, hosting lively Fourth of July block parties. He even braved – mostly against his will – the occasional family trip to Disneyland. But his true happiest place on Earth was Italy, a place he returned to often, whether with Debi or the whole family in tow.
Beyond his immediate family, Brian loved big family gatherings-the more raucous, the better. Whether it was Thanksgiving horse races at Golden Gate Fields, Easter white elephant with the same recycled gifts each year, or the overly-competitive annual Bocce Ball tournament, Brian thrived on a good time.
Brian had a knack of turning ordinary get-togethers into unforgettable memories. He hosted Christmas Eve parties that began at the dining table and ended with everyone dancing on the coffee table - even Grandpa. If you gave Brian control of the music at a party, there was a good chance you'd hear The Rolling Stones, and an even better chance the neighbors would too.
Brian's professional journey began as a kid behind the counter at Herb's Deli. In his adult years, he grew from construction journeyman to eventually founding Brian Spiers Development. As a visionary developer, he left his impact on San Francisco - particularly Market Street - with bold, vibrant projects. Along the way, he also owned two local dive bars, The Bitter End and Lucky 13, taking immense pride in both.
Outside of work, Brian had many passions. He loved his dogs (Maddie, Belle, and Penny), immersed himself in historical nonfiction, and grew a deep appreciation for wine, which led him to develop the new family home in Alexander Valley. A lifelong lover of soccer, he played for St. Gabriel's, Riordan, Glens, and The Overlords, later coaching all three of his children's teams. And for one day each year, he fancied himself a golfer at the Potato Head Classic.
Brian was a fiery spirit with a mischievous sense of humor and the loudest laugh in the room. But beneath it all, he also carried a quiet compassion he only revealed when it was needed most - often catching you by surprise. He operated by his own rules, spoke boldly, and never held back. Brian truly lived fully without hesitation. Or, as he would shout with a grin:
Tonight we ride. Tomorrow we water the horses.
