Board Director & Treasurer
As a queer, transracial adoptee from Bogotá, Colombia, Mara has a deeply rooted passion for building power among people, workers and communities historically disenfranchised and systemically marginalized. She believes deeply in self/community determination and approaches her coaching and consulting from the perspective that people already have the ability to accomplish their collective goals and shift the balance of power, and her role is to simply help be a guide.
Mara got her start in organizing at the University of Colorado and then eventually the University of Oregon. She has served communities as an organizer, a Lead Organizer, an Organizing Director, and eventually an Executive Director. Most recently, she built the country's first national organizing training program for workers, the Always Essential Fellowship, and has been leading that work since early 2021.
She currently runs her own consulting business, sits on the Board of Directors for On the Margins, and is the co-founder and a Board member for the Latino Alumni Association of the University of Oregon. She resides in El Paso, TX with her wife and their adorable dog, Emilio.
