Our Staff

Demis Foster, Executive Director

A life-long conservationist, Demis has over 25 years experience working on environmental campaigns and programs in the West. Demis grew up on a five generation family ranch in southern Idaho where she developed a lifelong love for nature, and a deep appreciation for the land and water that sustained the families in her rural farming community.

While earning a Bachelor of Arts in English and Creative Writing from Boise State University, she worked for the Wolf Recovery Foundation—the first organization in Idaho dedicated to the restoration of wolves in the Rockies. She then moved to the Pacific Northwest where she spent 15 years working on conservation campaigns, adventure and field science programs for youth, and overseeing a national environmental film festival. Demis was awarded the National Leadership Award for outstanding leadership in protecting public lands for her work as the Director of the Ancient Forest Roadshow—a year-long advocacy tour traveling across the nation with a 1,000-lb. crosscut section from an old-growth Douglas Fir tree.

She moved to New Mexico in 2010 to work on public lands and wildlife campaigns including the Mexican gray wolf recovery effort and the Rio Grande del Norte National Monument designation. She took the helm of Conservation Voters New Mexico as the Executive Director in 2013.

Roberto Aponte, Deputy Director of Operations

Roberto is our Operations Director, responsible for developing the strategy for and overseeing CVNM’s operational, administrative, human resources and financial systems.

He is a visionary manager and leader with more than 25 years in event production and organizational leadership, in both corporate and nonprofit settings. In addition to his expertise in business administration, Roberto has strong skills as a trainer, facilitator and coach. He has a Master of Arts in Business from the California Institute of Integral Studies, and an undergraduate degree in Communications from Emerson College in Boston. His unique master’s degree was focused on bringing environmental sustainability and social responsibility to the practice of business.

Roberto’s career success began when he recognized the importance of being able to integrate the fullness of who a person is into the work that one does. When he applied this principle to his own work life, he experienced less work-related stress, became a more effective and productive worker and lived a more fulfilling life. He then extended this approach toward life-work balance to the teams and projects he managed with increasingly positive results. Roberto’s vision is that all human beings develop a healthy relationship to their work, leading to a sense of community in their workplaces and thus making it easier to do work that supports balance with our natural environment and greater collaboration amongst all social groups.

Antonio Maestas, Diversity, Equity and Inclusion Coordinator

Antonio joined the CVNM Education Fund staff in September 2018. Antonio grew up in the community of Mountain View located in the South Valley of Albuquerque. His passion for community organizing sprouted from an environmental justice internship with the SouthWest Organizing Project in 2015 where he realized the circumstances of his childhood could be traced back to environmental disparities plaguing low-income communities of color. Following this internship, Antonio organized with the Tibetan Environmental Justice Movement in Dharamsala, India in the fall of 2015.  Returning back to the United States in the spring of 2016, Antonio was a lead education organizer to combat institutional racism and inequality at his college in Indiana.

When he returned to New Mexico, Antonio continued his environmental justice work with communities across Albuquerque, and with pueblo and land grant communities across the state. As a part of this work, he published a chapter titled “New Mexican Land Grants: A History of Conflict in the Chilili Land Grant” in a historical journal accounting the history of his land grant where he currently resides, La Merced del Pueblo de Chilili. One of Antonio’s great mentors told him, “Social movements are spiritual and the principles of environmental justice is our doctrine” for which he incorporates in his community organizing endeavors.

Antonio graduated from Earlham College in May 2018 with a Bachelor of Arts in Sociology/Anthropology with a concentration in Socio-Cultural relations. In his spare time, Antonio enjoys traveling, playing music, reading books and trying new foods.
