"Art is more than creativity—it is connection. By using art for community engagement, neighborhoods become more inclusive, empowered, and united. Art projects and programs strengthen civic identity, give voice to underrepresented groups, and foster both cultural and economic vitality."

She is an awarded Fellow of the Rockefeller Foundation’s Next Generation Leadership program (in Democracy and Social Justice) and was placed on a US Senatorial task force on de-institutionalizing the world’s children. Rebecca has served on numerous nonprofit boards and provides consulting services in strategy, development, communications and leadership.
In January 2025, when the world turned upside down, she met the moment by rebranding her practice as Defiant Strategies, LLC. with a hyper-local focus on helping nonprofits adapt and pivot through these highly uncertain times. ​In late 2025, Rebecca co-founded Kalderra to embrace joy, belonging and a thriving creative economy in her local community of Healdsburg.
