Golden Gate STEM Fair Leadership

Marcus Wojtkowiak, Executive Director, GGSF

Marcus WojtkowiakMarcus Wojtkowiak is the founding Director of the Golden Gate STEM Fair. In 2017 GGSF was formed to take the place of the previously active San Francisco Bay Area Science Fair. To keep this influential annual event going, Marcus and previous Director, Bob Fabini, rebuilt the organization and gathered a new leadership team. Previously Marcus coordinated the San Francisco Middle School Science Fair as the Randall Museum’s Science Program Coordinator. Marcus is passionate about providing an open forum where scientifically inclined students may present their research project to peers and be critiqued by the preceding generation of scientists.
