Aida Mariam Davis

Aida Mariam Davis
Chief People Officer

(she/her)

Born to an Ethiopian family in Baltimore, Aida Mariam Davis lived between multiple worlds. She is a descendant of anti-colonial fighters who kept Ethiopia free from colonialism when virtually all of Africa was carved out and divided among European powers. She was raised in Apple Valley, CA where her father was a member of the Mojave Desert Sierra Club and instilled a love of people and our planet. She left Apple Valley to attend UC Berkeley and it was there in Oakland that her life of activism sparked. In college, she worked for Malcolm X Grassroots Organizing (MXGM), then for Congresswoman Barbara Lee, who invited her to join the Gathering of the Elders -- a meeting of civil rights leaders and young people to dialog across generations, experiences, and communities to advance social, economic and environmental justice.

These formative experiences are the foundation for her work with the People Team at Sierra Club. Before joining the Sierra Club, Davis led Decolonize Design, a boutique consulting firm with clients spanning the nonprofit sector, philanthropy, and Fortune 500 companies. She created the Belonging, Dignity, Justice, and Joy (BDJJ) framework as a powerful and sustainable alternative to the often superficial Diversity, Equity and Inclusion (DEI) industrial complex. As a longtime community organizer-turned-founder of Decolonize Design, she believes that successful movement building is not rooted in transactional processes, but instead in deep relational efforts that speak to our universal sacred personhood and sustainability of our earth.

Davis lives in Tongva territory with her family. She acknowledges the Gabrielino/Tongva peoples as the true stewards of the unceded territory of Tovaangar (the Los Angeles basin and So. Channel Islands). She pays respects to the Honuukvetam (Ancestors), ‘Ahiihirom (Elders) and ‘Eyoohiinkem (our relatives/relations) past, present and emerging.

Ben Jealous

Ben Jealous
Executive Director

(he/him)

Ben Jealous is the 7th Executive Director of the Sierra Club. Founded in 1892, it is America's largest and oldest organization of local volunteers dedicated to exploring, enjoying, and protecting the outdoors.

Ben may be best known for being the youngest national President and CEO in the history of the NAACP. He led the organization through tough financial times and to record growth in membership and fundraising.

Born to parents who met as civil rights activists and became Sierra Club members, Ben's commitment to preserving wild places and defending embattled communities was evident early on. At 13, he completed a college marine biology course and became the youngest volunteer guide in the history of the Monterey Bay Aquarium. At 14, he organized high school students to help Jesse Jackson's pathbreaking 1988 campaign for president. At 15, he helped organize a protest against the clear-cutting of old-growth redwoods at the California State Capitol.

In his 20s, he was an investigative reporter for Mississippi's frequently firebombed Jackson Advocate newspaper. There, he helped free a black farmer who had been framed for arson and a white inmate who had been targeted for helping to convict corrupt guards who had murdered a prisoner. His most extensive reporting was on industrial poisoning and cancer clusters among children in a rural black community.

His first major action as head of the NAACP was to establish climate justice committees throughout its network of more than 2,000 local chapters and help lead them to support the Sierra Club's Beyond Coal Campaign. Ever the coalition builder, he would later help convince the Sierra Club to join the NAACP in fighting to defend voting rights.

Ben is a natural-born bridge builder with deep American roots, the son of a black mother and a white father who left whose marriage was illegal in 17 states. He is cousin to U.S. President Thomas Jefferson, Confederate General Robert E Lee, and the formerly enslaved American turned First President of Liberia, Joseph Jenkins Roberts. He is the direct descendant of 6 officers in the Massachusetts Regiment of the Continental Army, the youngest child combatant at the Battle of Lexington and Concord, and two of Virginia's earliest Black legislators.

A Professor of Practice at the University of Pennsylvania, he teaches leadership and social entrepreneurship courses. The former Rhodes Scholar's latest book, Never Forget Our People Were Always Free: A Parable of American Healing, was published in January 2023. An avid paddler, skier, and hiker, Ben lives in a bird sanctuary on the Chesapeake Bay with his children Morgan and Jack and their dog Charlie.
