With 13+ years of experience leading brand marketing and creative production at companies like Todd Snyder, Shinola, THINX, and Buffy, she’s known for building immersive, values-driven experiences that foster connection and spark meaningful dialogue.

She holds a Master’s in Sustainability Management from Columbia University, where she deepened her commitment to advancing circularity in consumer culture.

Her mission is to help shape a more connected, circular future—one gathering at a time.
