About Sibby

cupcake

Sibby Ross Thomsen founded Sibby’s Cupcakery in 2004 with the mission of providing joy and happiness to her customers and community. She perfected her cupcake recipes on the side during a 10-year career in advertising. Some of her favorite memories of those days were the mocha-torte lunches she frequently enjoyed with friends, who were often the recipients of her elaborate birthday cake creations.

Sibby began her baking career at age 4, making blueberry-peach pies with her mother in Topeka, Kansas. She serves on the board of the San Francisco Bakers Dozen, a non-profit organization for Bay Area baking professionals and enthusiasts.
