the Process

Success for us is measured by the increase in opportunities for the next generation of leaders that are now being recruited to serve on the boards of environmental and conservation groups.

Upon graduation of the fellowship, fellows will join a cadre of Vanguard alumni, be able to apply a new set of critical governance skills to the boards they sit on and strengthen GLT’s collective work to strengthen the power of the environmental movement nationally.

We are pleased to present our

2022-2023 Vanguard Fellows















Testimonials from Vanguard Alumni

For me, the fiduciary meeting impacted me the most. I liked the creation of a safe place to give our concerns.

Kenya L. Goodson

Black Warrior Riverkeeper, Cahaba River Society, Conservation Alabama

Being paired with a mentor, the speakers, the conversation

Natasha DeJarnett

Citizens' Climate Education, Physicians for Social Responsibility

Connections with other members and mentors; personally for my board service, Jim Taylor (culture) and Ignacia Moreno (culture/power) were especially resonant. Hearing stories from others, resources in the forms of slides and readings. Seeding the sessions with discussion questions, requests for reflection and pre-readings.

Taylor Jang

Bay Area Ridge Trail Council

The mentorship assignment was a wonderful experience.

Roshan Patel

Wildlands Network

All of it! Of the instructional workshops, I definitely grew the most in the myths of board service and conflict resolution sessions. I also got a lot out of my few meetings with Ignacia. We both had really busy schedules, so it was difficult to find time to connect, but when we did, they were extremely valuable. I learned a lot about myself in those deeper dives.


National Audubon Society

The mentorship approach was the most impactful part of the program for me. I loved my monthly chats with Alison and learned an incredible amount. The other highlight was the final session when I learned the most from the other fellows about what they learned from the program and how they are thinking about applying what they learned to their boards of directors.



I was honored to be selected for this program, truly. I think it is tremendous offering. Unfortunately, due to my schedule, I was not able to fully participate.

Vanguard Fellowship

Green Leadership Trust is the first cross-sector network of Black, Indigenous, and People of Color (BIPOC) fiduciaries that serve on the boards of U.S. nonprofit environmental organizations. Our members include individuals with a wealth of knowledge and decades of experience navigating predominantly white in environmental and conservation nonprofits.

The Cecil Corbin-Mark Vanguard Fellowship is a six-month development program where we leverage our combined talent and shared knowledge to impart valuable lessons with the next generation of environmental and conservation leaders of color. The program is designed as a peer-to-peer learning experience primarily executed in a virtual setting with in-person training opportunities when possible.

Through a series of trainings, Vanguard Fellows will be exposed to the knowledge and experiences from their peers on the essential functions of board service, specifically for people of color. Speakers are veteran board members, some of which can be regarded as trailblazers having served as the first or the only board member of color in their spaces.


Success for us is measured by the increase in opportunities for the next generation of leaders that are now being recruited to serve on the boards of environmental and conservation groups. 


Upon graduation of the fellowship, fellows will join a cadre of Vanguard alumni, be able to apply a new set of critical governance skills to the boards they sit on and strengthen GLT’s collective work to strengthen the power of the environmental movement nationally.

The Vanguard Fellowship is named to honor the legacy of Cecil Corbin-Mark (1969 – 2020).

Cecil D. Corbin-Mark, the Deputy Director and Director of Policy Initiatives at WE ACT, was the most brilliant and effective environmental champion. A member of Green Leadership Trust since 2014, Cecil was a force to be reckoned with. We hope our fellows build on Cecil’s legacy by championing justice and equity for the environmental movement.

Judith Santano

My name is Judith Santano and I graduated from Stanford University in 2019 with a B.S. in Earth Systems. During undergrad I studied ecology and how it is intersects with education, communication, and justice. I’m currently in the process of applying to graduate programs where I hope to continue to use ecology to inform my work as an environmental educator, and leverage my skills to advocate for Black, Indigenous, and People of Color. I currently serve on the Board for Earthwatch whose main mission is to connect people to science through citizen science expeditions. I first came to Earthwatch as an Ignite Fellow in 2013, and then as their Educator Programs Intern in 2017. As someone who has strongly benefitted from Earthwatch, I want to expand the reach of their programs to serve more First Generation, Low Income Students of Color like myself.
