Rosita Scarborough, Senior Network Engagement Director

Rosita Scarborough has 20 years of experience including numerous roles with The Nature Conservancy. She started her career as an Office Manager with a field-based program in Florida, eventually becoming the first Conservancy employee to be permanently stationed in Africa and responsible for establishing the organization’s infrastructure on the continent, and rising the ranks to become one of TNC’s Executive Council members, where she served as interim Chief Diversity and Inclusion Officer.

Rosita is excited to be with US CAN now as it brings her back full circle to her ‘roots’ in conservation based on her life and experiences growing up in Kenya where her mom and aunt established a grassroots conservation movement centered around human rights, environmental advocacy and civic empowerment. Her current role with US CAN as the Senior Director of Network Engagement will entail building relationships, trust and alignment between US CAN members, and also moving them towards reaching US CAN’s vision by facilitating work that they co-create together.

Lindsay Harper

Lindsay Harper | Arm in Arm National Core Support Team Coordinator

Lindsay Harper began her work in environmental, economic and social justice in 2013 with the launch of her flagship global initiative GreenGoingForward. She recognized then that there is a need to engage diverse communities through various collaborations including new media, small businesses, and the nonprofit sector.

Lindsay believes that in seeking economic development, utilizing a community-lead approach to business education can facilitate strong #InKind economies, create multi-generational wealth, and build leadership and capacity. Applying these principles will directly address the systemic economic issues perpetuating the climate crisis. 

Lindsay was appointed to the position of Executive Director for Georgia WAND (Women’s Action for New Directions) in 2018; the first African-American woman to hold the position.
