Ellington is also executive director of the historic Ruth Williams Bayview Opera House, a cultural center in the Bayview-Hunters Point area, and has been on three city commissions, including the Community Investment and Infrastructure Commission. He was previously an executive at a public-affairs and communications firm, a director of homelessness initiatives and community development for The Salvation Army San Francisco, and public-affairs director for the Golden State Warriors.

Among those challenging Ellington is Dion-Jay “D.J.” Brookter, a nonprofit executive and former member of San Francisco’s Committee on City Workforce Alignment, who reported on Oct. 21 having raised $10,585. J.R. Eppler, an attorney who until recently was a commissioner on The City’s Board of Appeals, said Tuesday he had raised more than $30,000. Eppler is the president of the Potrero Boosters Neighborhood Association and volunteers with several other local groups.
