Call for Nominations

The Sierra Club San Diego Nominating Committee is seeking Chapter members to run for the Chapter Executive Committee (ExCom) in the 2019 Election. The committee seeks a diverse pool of candidates, balanced in terms of gender, ethnicity, and geography. The Sierra Club San Diego membership will elect four Executive Committee members in 2019.  Nominations are due July 25, 2019.

We will actually have two elections running concurrently for Sierra Club San Diego ExCom. We will elect two new people to a one-year term on Excom. We have a second simultaneous election to a three-year term on ExCom. Please consider running for one of these two important seats.   Read more here…
