Meet the Earth Team Staff

Manuel Alonso

Executive director

Born in Spain, Manuel is an anthropologist and archaeologist interested in the protection of cultural and biological diversity. He has been working with environmental non-profit organizations for more than 25 years in Europe, Central, and South America and the United States. Manuel has been with EarthTeam since 2013.

Little Known Fact: Manuel loves to hike in the wilderness with his two (or three!) big golden retrievers. He was the founder of the TUVA Foundation, (United Lands of Neighbors for the Environment) and acted as its Executive Director for 11 years, from 1990 to 2001. As a local nonprofit headquartered in the town of Puerto Jimenez, TUVA launched collaborative community-conservation initiatives in a highly conflictive area that in 1989 had the highest deforestation rate in the world, finally saving over 5 million trees in a 20,000-acre buffer zone around Corcovado National Park, in southern Costa Rica. TUVA’s pioneering “working landscapes” approach built a coalition of stakeholders including local residents, landowners, government agencies, eco-tourism operators, illegal loggers, gold miners, indigenous groups and a wide network of over 50 local, regional and international organizations. TUVA also played a key role in the Stone Container campaign in 1990, a transnational industrial forestry project that threatened the integrity of local forest ecosystems. In 1990 TUVA also started the Osa Sea Turtle Study, a community-based effort to protect several endangered species of sea turtles. TUVA’s story was featured in NPR’s Living on Earth Top Story in 198.

This 10- year effort resulted in groundbreaking agreements that successfully protected cultural and biological diversity in an extensive “working buffer zone” around Corcovado National Park, conserving landscapes and providing new economic alternatives to local residents, including the beginnings of the Smart Wood certification program to support sustainable local communities. According to National Geographic, Corcovado National Park’s 150,000 acres contains the richest rainforests in the world and is the “most biologically intense place on Earth”. Today, TUVA’s legacy continues and has expanded under the management of a new organization, Osa Conservation, that took over operations in 2005.

Joelle Alley

Program Director

Joelle graduated from the University of California Santa Barbara with a degree in Environmental Studies. She focused her studies on environmental policy, primarily in relation to agriculture and water resource management. While living in Santa Barbara, Joelle worked as an outdoor educator at a local sustainable agriculture nonprofit called Fairview Gardens. She also worked as the regional intern at the Ventura, CA office of California Trout. During her last year as a student, Joelle spent the majority of her time researching for and writing her thesis about the implementation of the Sustainable Groundwater Management Act in California. Joelle hopes to use her background as an educator and her passion for community engagement in environmental issues to make a difference in her childhood home, the wonderful East Bay.

Itzel Gomez

Program Manager

Itzel graduated from the University of California, San Diego with a degree in Environmental Engineering. In college, she developed an interest for topics in hydrology and water resources as well as environmental justice issues related to water quality and conservation. During her time as a student she served as Outreach Chair for the UCSD Society of Hispanic Professional Engineers (SHPE) where she was able to foster her passion for encouraging youth of color to pursue careers in STEM fields. Itzel was born and raised in San Pablo, CA and knows the East Bay to be her home. She is excited to be joining Earth Team this year and have the opportunity to work with young leaders of the next generation to give back to the communities she grew up in. She recognizes the severity of climate change effects within underrepresented communities, both locally and globally, and is passionate about educating others towards implementing more sustainable practices in their daily lives.

Naomi Lichtenstein

Campus Coordinator

Naomi graduated from the University of Maryland, College Park with a degree in environmental science and policy. She focused her studies on global climate policy and environmental justice research, primarily focusing on including marginalized communities in decision making when it comes to larger scale development projects. While living in D.C., Naomi interned for the State Department in environmental defender research and worked in environmental education at the White House Visitor Center through the National Park Service. Naomi also worked as the Internship Coordinator after graduating from college for an international nonprofit focusing on engaging youth in animal awareness and connecting young professionals to environmental careers. Naomi wishes to use her experience to work in global science diplomacy one day and engage in conscious negotiations, considering all parties affected, to make a difference in sustainability and equality.

Healey Cayabyab

Campus coordinator

I graduated from San Jose State University with a degree in Environmental Studies with a minor in Sustainable Energy. In my journey, I became very invested and interested in the environment through a program in my old high school. The program was called Week Without Walls, and from there was able to join a group for backpacking. Since then, I have always the environment and wanted to keep the natural beauty of the world the same. During my last year at San Jose State University, I was an intern for the California Native Garden Foundation to help support learning and acitivites for children under the ages of 10. I was also an intern for San Jose State University’s Center for Developmental Recycling where I assisted and expedited residents of Santa Clara County’s household waste to dispose of it correctly. From these two experiences, it spurred my love to educate as well as research ways to use our energy more efficiently. 
My love for sustainability leads me to make changes in my daily life as well as educating others the importance of implementing sustainable practices to limit our own carbon footprint on the Earth. Happy to be a part of Earthteam to not only work with aspiring young environmental leaders, but as well as cultivating the next generation.

Kaylee Pierson

Program Associate

Kaylee graduated from Sewanee: The University of the South with a degree in Natural Resources and the Environment. Access to her forested 13,000 acre campus fostered her love for the natural world and inspired her focus studies in hydrology and forestry specifically. While in college, Kaylee studied abroad in New Zealand, sailing in the South Pacific researching climate change effects on the global ocean.

After graduating she joined the U.S. Peace Corps as a Coastal Resource Management Volunteer in the Philippines. Living in a small coastal fishing community, she worked with the local government to implement natural resource management projects as well as conduct environmental education programs with local grade schools. She became passionate about small-scale conservation after integrating into the Filipino community and learning more about their relationship with the natural world and their respect for its resources. Kaylee then went on to work as an American Conservation Experience Volunteer for AmeriCorps in Santa Cruz, doing trail and restoration work all around Northern California, sparking her love and appreciation for the Bay Area.

As a Program Associate for Earth Team, Kaylee is excited to work closely with Bay Area students who are passionate about environmental change and being a part of local conservation efforts in their community.
