Teresa Marlene Yost
Dec. 20, 1957-Feb. 25, 2026
Folsom, California

Teresa Marlene Yost, a beloved mother, entrepreneur, and Folsom community fixture, passed away peacefully on February 25, 2026, at the age of 68. After a long illness, she died surrounded by the family who was the center of her world. Born in Oakland, California, on December 20, 1957, to Manuel Peter Del Arroz and Marlene Bebe Vogt, Teresa’s journey took her through the heart of Northern California. In 1966, she moved to Concord, where she discovered her love for country living and formed friendships that would last a lifetime. By 1973, she moved to Dublin, graduating from Dublin High School in 1976. 1976 proved to be a milestone year, as she also met her future husband, Danny Yost. They married in 1978. Together, they raised three sons — Ryan, Matthew, and Nicholas — who remained the absolute light of her life. In 1985, the family moved to Folsom, sparking the entrepreneurial spirit Teresa was best known for. Driven by a desire to fill her home with antiques she couldn't yet afford, she became a self-taught expert on Sacramento-area auction houses. This passion blossomed into "As Time Goes By," her business in Old Town Folsom. Starting at The Folsom Mercantile co-op before opening her own storefront, Teresa spent over 20 years as a cornerstone of the local antique and gift community. She was a true adventurer, traveling across the United States on buying trips, with a particular fondness for the treasures found in Nebraska and Iowa. However, it was her unique companion that made her a local legend. Teresa’s love for animals was personified by Duke, her pet pig, who accompanied her to the shop every day. To many in Old Town Folsom, she was affectionately and famously known as "The Pig Lady." Teresa was preceded in death by her father, Manuel Del Arroz, and her brother, Danny Del Arroz. Her legacy lives on through her devoted sons, Ryan, Matthew, and Nicholas; her mother, Marlene Bebe Vogt; her brother Manny and his wife (and Teresa’s dear friend) Juanita Del Arroz; and her sister Diana Klinger and husband Rick. She is also survived by her extended family, including Ned and Deborah Yost, Karen and Bill Lehto, and Billy and Nicole Moffitt. Teresa will be remembered for her sharp eye for beauty, her tenacious spirit, and the warmth she brought to everyone who was lucky enough to step into her life.

The family wishes to extend their deepest gratitude to the exceptional care team who supported Teresa in her final days. Marie, her hospice aide, provided gentle, dignified care that brought Teresa immense comfort. Petra and Jaspreet, her dedicated nurses, offered not only expert medical guidance but also profound compassion and strength to the entire family. Yeng, her social worker, showed abounding mercy, genuine empathy and dedication to easing our emotional pain, and guided use during life's final chapter. Their kindness transformed a difficult journey into one filled with peace and grace; they truly became like family during this time.
