Person

Jeffrey Siminoff

Jeffrey Siminoff and his team focus on workplace dignity, connecting Robert F. Kennedy Human Rights’ legacy human rights work and the values that underlie it to the workplace.

A former employment lawyer, Jeffrey has extensive experience as an inclusion and diversity, workplace culture, and social impact leader and consultant. He has expanded the inclusion and diversity functions at top Silicon Valley companies, including Twitter and Apple, where he was recognized as one of 10 men making waves for women in tech. In these industry-leading positions, Jeffrey and his team prioritized inclusion in key people processes, creating more intentionality and engagement around what an inclusive culture should be, establishing relationships across the tech industry and organizations that work with it, and thinking differently about how these companies showed up outside of the workplace, including as a business and community engagement matter.

Jeffrey is based in San Francisco, having moved to the Bay Area to work for Apple. Prior to that, he led the global diversity and inclusion function at Morgan Stanley, a role he took on after leading the Pride (LGBTQ) Employee Resource Group, a transformative experience for him. In addition, Jeffrey practiced employment law and litigation for Morgan Stanley in New York and London, and he led the legal division’s diversity committee. He began his career in private law practice.

Jeffrey is a graduate of Duke University, where he studied public policy, and he received his law degree from Emory University. He is a pretty intense foodie, and a fan of travel and fitness.
