Roxie Bostwick

Roxie is incredibly honored to serve as the 90th President of Spinsters of San Francisco (SOSF). This is her fourth year in SOSF, and in this role she will be overseeing both the Board of Directors and the wider organization. In the past, Roxie co-chaired Annual Ball and was an involved member of the Charity Outreach and Membership Selection Committees. 

Last year, Roxie had the privilege of being Vice President. This experience taught her invaluable lessons about not only how to run an organization of this scale and caliber, but also the power that each member holds to make a difference in our community.

Outside of Spinsters, Roxie is the Senior PR & Communications Lead at Skillz, where she has built the leading startup’s public relations department from the ground up over the past four years. A recipient of the 2019 American Business Award for Communications Professional of the Year and the 2018 PRWeek U.S. Champions of PR Award, Roxie has also helped secure Skillz acclaim including the #1 ranking on the Inc. 5000 as the fastest-growing private company in America. She is excited to contribute both her management experience and her passion for events, branding, and effective communication to SOSF as President.

Originally from Tucson, Arizona, Roxie came to call San Francisco home after graduating with a B.A. in Media Studies and a minor in Spanish from UC Berkeley. Outside of Spinsters, she is also a member of San Francisco Ballet’s ENCORE! young professionals group and volunteers as the Recruitment Advisor for the UC Berkeley chapter of Kappa Alpha Theta.

Roxie is proud of the positive impact Spinsters have had on the Bay Area community over the past 90 years, and knows how each SOSF annual contribution (in terms of both volunteer hours and funds raised) makes an important difference. Spinsters has also become a home for women of all backgrounds to find everything from their voices and passions to their future jobs and roommates.

Roxie is honored to be surrounded by this group of smart, talented women and looks forward to giving back to all of them this year by executing activities that are enjoyable for the membership, impactful for the SOSF nonprofit partner (La Cocina), and beneficial for the organization’s brand recognition in the local community.

This year, a core focus for Roxie will be continuing the Spinsters legacy of collective success while also effectively using the organization’s resources to help members find what they were looking for upon joining – and stay connected to Spinsters for many years to come, whether as an active member or alumnae. 

Roxie can’t wait to lead this wonderful organization in its 90th year. She believes that together we can be far greater than the sum of our parts, but also that every individual fundamentally matters. This principle will guide her efforts all year.

The Spinsters of San Francisco are the manifestation of a vision established by other trailblazing women back in 1929. Roxie is excited to make the SOSF founders proud by setting the tone for the next decade leading up to the organization’s centennial anniversary.
