Mary GiardinO, Development Director

Mary G Bio Pic.jpg

Writer, Editor, Mediator, Advocator, Agitator - is a native, 2nd generation American/Coloradan who spent half of her life in Northern California. Protecting the natural world has been an automatic reflex since she was a child. After studying Creative Writing and World Religions at the University of Colorado, Boulder, she took up residence in what she calls Boulder-by-the-sea: Santa Cruz, California. Staying close to the production of food - her first love - Mary learned the gracious art of service.  

After a glorious stint of seacoast living, she found a profound home among redwoods and rebels. Living 12 years off-grid in the forest, among people who worked hard at self-sufficiency and valued community & diversity, Mary learned how to put the art of service to work. Alongside community, Mary fought to save forests; co-create a world of art & music; support independent radio, local education, and environmental resistance; and built a farmer’s market and a town square. She helped organizations thrive through board of directors service, community leadership, resource development, conflict resolution, and community organizing. 

Emerging from the forest as a certified mediator; certified child, client and family advocate; and a non-profit professional, Mary moved back to Boulder to raise her two daughters - now 13 & 18 - close to her big Italian family. Mary’s focus is now on disrupting the dominant paradigm by bringing her art of community service and environmental activism out into the larger community.

Kellie Berns, Project Manager


Kellie Berns is a visionary, spiritual practitioner, teacher and community organizer who has a passion for bringing peace, justice and healing to those in need. Her time spent studying and practicing Buddhism, Advita Vedanta and in earth based Native Americans ceremonies ignited a deep spiritual calling within her to be of service to humanity. The understanding that all beings are connected, and that if one being is suffering, we all are, is what moved her off the meditation cushion and into the world of direct action.

After teaching yoga, meditation and massage therapy for many years, she moved to Philadelphia, PA where she co-directed the Ahimsa House, a community center which merges activism and spirituality, and stands outside of the violence of capitalism by offering all classes free of charge. The project serves to give voice to underserved communities using the principles of compassion and non-violence. In 2013, Kellie Co-founded a Yoga Teacher Training in west Philadelphia which encouraged bringing yoga to lower income areas, and to people of mixed race and gender identification. Her passion for teaching stems from the knowledge that when there is peace within, there is peace without.

In 2016, Kellie’s relationship to various Indigenous tribes of the Americas, as well as her love for water, drove her across the country to Cannonball, ND where she spent 2 months living and participating in the Standing Rock movement. Working in harmony with her Native and non-Native allies, she learned more about non-violent front lines direct action, as well as how to create a movement with prayer at its center. Kellie now lives in Boulder, CO and is continuing her work of heart-forward, direct action with the Earth Guardians.
