Arthur B Hill
ARTHUR B. HILL | Founder of the Hill-Snowdon Foundation

Arthur Bullock Hill was born to homesteaders in Oklahoma City on October 20, 1892. As one of many children, money was very tight in the Hill household. He left school at the age of twelve to go to work at a drugstore, which he purchased within a few years. In his early twenties he sold the drugstore and took a job in pharmaceutical sales. On a sales trip to Dallas, he met Marguerite Stewart. They married in 1914 and settled in Dallas. Lillian Lee, their only daughter, was born in 1919 and married Edward Snowdon in 1941.


On another sales trip, Arthur met a senior manager of Johnson & Johnson (J&J), which was fast becoming the nation’s largest medical product company. When Arthur was offered a job with the firm he moved the family to Chicago in the early thirties to head the Midwest sales division. In the late thirties, the Hills moved to New Jersey to be near J&J’s New Brunswick headquarters, settling first in Bound Brook and later in Plainfield.

Despite his lack of formal education, Arthur worked his way up in the company. When he retired in 1948, he was the Vice President of Sales and on the Board of Directors. Arthur retired relatively early for health reasons but remained on the Board for several years after his retirement. The company went public in 1943, and like many senior executives, Arthur took stock options in lieu of pay during the war. This would prove to be a fortuitous move, as stock prices steadily climbed over the following decades while the company expanded and diversified.

After his retirement, Arthur became more involved in social and civic life in Plainfield. He was active in a number of social organizations and local charities. He founded the local Community Chest, which later became the United Way of New Jersey. He also supported a home for wayward boys in Nebraska and funded a settlement house in the Black neighborhood of Plainfield. As a result of his humble beginnings, Arthur felt it was his responsibility to help those less fortunate. But he also believed that individuals are responsible for helping themselves, as he had done. He had a deep understanding of the medical system and worried that the unequal access to decent healthcare would lead to serious social unrest.


In 1959, Arthur founded the Hill-Snowdon Foundation in New Jersey with several thousand dollars in assets, primarily J&J stock. He served as a trustee until his death in 1983.

Maria Brenes

Maria Brenes is the Executive Director of Bold Vision LA


María is the proud daughter of immigrants from Mexico who settled down in Los Angeles with dreams of starting and raising a family in the United States. María is the eldest of four and lived in Los Angeles until the age of nine after her father suffered an accident that made his job as a gardener challenging. As the sole breadwinner, remaining in LA was economically challenging. María’s family moved to the border town of Tecate in Baja California, Mexico. To support his family, Maria’s father became a border commuter worker, and María and her siblings crossed with him to attend public schools in East San Diego County. Her parents’ sole dream was for their children to go to college.


From an early age, María experienced first-hand societal inequities. As a child, she and her younger brothers crossed the border hoping to get prepared for higher education. But this was not without struggle. In 1993, at the eve of the state ballot measure Proposition 187, María and her peers became the target of anti-immigrant sentiment and harassment that was brewing in California. She refused to stand down. María organized hundreds of families to speak out against the racism and injustice they were enduring. Together, María and a groundswell of families urged the media and elected officials to listen to their cry – that regardless of skin color or ethnicity – Education is a Civil Right!  

After graduating from UC Berkeley, María continued her work as a community organizer working to build greater unity and empowerment with Black, Brown and Asian American and Pacific Islander students at an Oakland public high school. She then went on to earn her Master’s in Education at Harvard University, where she became the first-ever Latina-elected student body president of the graduate school of education. 

In 2002, María returned to Los Angeles and began working as the Youth Organizing Director for InnerCity Struggle, advocating for educational and housing justice in the Eastside of Los Angeles. In 2006, she was appointed to serve as Executive Director. Due to María’s leadership, today there is a powerful voice for students and families on the Eastside, ensuring those most affected by the decisions of elected officials – parents and students – can advocate for the education and housing justice and resources they deserve. 

For over twenty years, María’s leadership helped youth and families secure historic wins for Eastside communities, including: 

  • In 2004, winning for the first time in over eighty years 5 new LAUSD public schools for the Eastside.

  • In 2005, winning the historic A-G Life Prep Resolution, a landmark policy ensuring all LAUSD high school students had access to college preparatory courses to graduate college-ready.

  • In 2013, securing the passage of the School Climate Bill of Rights that eliminated willful defiance suspensions in LAUSD that disproportionately targeted youth of color and led to the approval of alternatives to punitive discipline resulting in increased graduation rates. 

  • In 2014, 2018 and 2021, winning the Equity is Justice LAUSD Resolutions, which annually allocates millions of new funding to highest need schools impacted by historic disinvestment.

In response to both the COVID-19 pandemic and housing crisis, María led organizing and advocacy efforts resulting in County policies that ensured greater tenant protections including eviction moratoriums for unincorporated areas of Los Angeles County. Efforts also resulted in a winning campaign to secure a new affordable housing development in East LA. 

An experienced leader rooted firmly in a commitment to justice, María has been recognized by LA OPINION, the Liberty Hill Foundation, UC Berkeley’s Chicano/Latino Alumni Association of Southern California, the Latina Lawyers Association, the LA Dodgers, and the Dolores Huerta Foundation. Since 2015, she has served as a Commissioner for the LA County Commission for Children and Families, appointed by Supervisor Hilda L. Solis. Furthermore, in 2018, the LA County Commission for Women gave María the Woman of the Year Award. In 2023, Assemblywoman Wendy Carrillo announced María as the Woman of the Year for the California 52nd Assembly District, recognizing her as an effective and impactful education advocate. She also serves as a Community Trustee for the Board of Directors of the Hill Snowdon Foundation, a national social justice fund. 

María lives in El Sereno with her family and her two children who attend LAUSD schools, where she has been an active parent volunteer.

Judith Browne Dianis is Executive Director of Advancement Project National Office.  

Dianis has served as a lawyer, professor and civil rights advocate in the movement for racial justice. Hailed as a voting rights expert and pioneer in the movement to dismantle the school-to-prison pipeline, Dianis leads Advancement Project National Office’s work in combatting structural racism in education, voting, policing, criminal justice and immigration.

Since joining Advancement Project at its inception in 1999, Dianis has worked with grassroots organizations to wage successful campaigns using litigation, advocacy and communications. Dianis authored groundbreaking education reports including: Opportunities Suspended and Derailed: The Schoolhouse to Jailhouse Track, detailing the unnecessary criminalization of students by their schools. Advancement Project National Office’s work with grassroots partners significantly helped decrease student suspensions and arrests in Denver, Baltimore and school districts throughout Florida.

Taking from civil rights activist Ella J. Baker’s philosophy, Dianis’ belief in the “genius of ordinary people” has helped Advancement Project National Office combat discriminatory voting rights measures. For nearly two decades, the organization’s Voter Protection Program has partnered with civic engagement non-profits to thwart voter suppression efforts like strict voter ID requirements, cuts to early voting, the closure of polling locations and felony disenfranchisement. Advancement Project National Office is proud to be a founding member of the Florida Rights Restoration Coalition, recently credited with the historic passage of Amendment 4 to the Florida’s state constitution. The measure automatically restores the voting rights of those with prior felony convictions.
