Our Chapter
Yale Blue Green’s San Francisco chapter has been active since 2018. The San Francisco Bay Area Chapter of Yale Blue Green recently re-launched its work to advance the YBG mission. We developed plans for in-person events focused on service, education, and networking. We are glad for all who have joined our events and hope you will participate in those coming up. We would love to hear from you and your suggestions about the YBG SF Bay Area Chapter, including whether you would like to take on a role leading our YBG activities. If you or someone you know is interested in joining the leadership team, please email the co-chairs to express your interest and to receive notifications about events.
