Megan Meder, Sonoma Natural Resources Manager

Megan was first exposed to CCNB and its mission in 2012 when she worked alongside a crew as a Natural Resources Program Assistant for the Sonoma County Water Agency in their Stream Maintenance Program. She worked as a Consulting Utility Forester for PG&E for the next several years where she cemented her tree knowledge and also became an ISA Certified Arborist.

Megan joined CCNB in 2017 as an Assistant Supervisor wanting to expand her leadership skills and inspire others to become passionate environmental stewards. Her dedication to the corpsmembers was undeniable and she was soon promoted to Supervisor. She has continued to grow as a leader in the roles of Sonoma Natural Resources Coordinator and Senior Coordinator and now as a Natural Resources Manager.

Adrian Brumley, FIRE Foundry and Special Projects Coordinator

Adrian is from Round Valley, coming to CCNB with six years of firefighter experience, and two years of emergency management experience. He also has 20 years of coaching experience, coaching football, baseball, basketball, and boxing. His joint passions are coaching and the fire service, so being able to combine both in running the fire foundry program is a dream job for him.

His goal is to build, coach and motivate the recruits so much that when they succeed the call me and tell us that this program was the best thing that ever happen to them; he can’t wait to bring them back to tell their success stories to the recruits classes that follow them. In his spare time, Adrian enjoys spending time with his children and family, taking care of his farm animals, and being out in the woods, whether it be camping, mudding, riding quads, or fishing.

Mariah Chastain, Sonoma Natural Resources Coordinator

Mariah joined CCNB in June of 2020 after graduating college as a temporary crew supervisor. She hit the ground running, never backing down from the numerous challenges presented to her and quickly earned a permanent supervisor position. After a whirlwind of six months, she was promoted to Sonoma Natural Resources Coordinator. She is a proud first-generation and Native college graduate from Sonoma State University where she received a degree in Environmental Studies and Planning with a concentration in conservation/restoration and a minor in Biology. She is passionate about social justice issues, environmental justice and equity, and inclusivity. She previously was an intern with Sonoma Land Trust and was the student coordinator for Outdoor Pursuits at Sonoma State.

Mariah lived and studied biology for eleven months in Wales, United Kingdom and travelled to eleven countries. She has had to overcome many barriers in her life and is ecstatic to be working with youth and coworkers she can relate to. When she is not in the office, she is hiking, doing yoga, or snuggling with her puppy.

Matt Lunn, Senior Natural Resources Coordinator

Matt became a part of the Natural Resources team in the Spring of 2022, but was already familiar with the work of corps from his time running an outdoor youth program just outside of Yosemite National Park and collaborating with a local corps crew there. Prior to that, he served in the AmeriCorps, helping to educate students and volunteers in renewable energy technologies in Southern California. Now he combines his experiences in education, environmentalism, and workforce development to coordinate programs and projects while providing direct support to staff and individual corpsmembers. 

With an academic background in Sociology from Cal State University San Marcos, Matt seeks to build upon this knowledge by weaving it into work centered on sustainable land management principles that also incorporates the wisdom and traditional practices of indigenous groups and other local cultures. He wants to help underserved youth find opportunities in conservation and strengthen their connection to nature, so that they not only become protectors and stewards to the environments they live in but direct beneficiaries of the economic upsides that come from maintaining healthy ecosystems. In the long term, Matt plans to explore the role conservation will have in the emerging field of regenerative agriculture, as large swaths of historic working lands become unsustainable and unprofitable, left vulnerable to commercial development. 

In his free time Matt enjoys outdoor adventure, art, gardening, and live entertainment. He has a dog named Bo that tags along most places and loves to hike, swim, and chase squirrels.

Santiago Roman, Marin Natural Resources Coordinator

Santiago (they/them) joined CCNB in the fall of 2020 as a temporary supervisor after graduating from Oberlin College with a degree in Environmental Studies. After half a year of hard work developing their skills in natural resources and pursuing their passion for environmental justice, they transitioned into a permanent supervisor position. Just three months later, Santiago was promoted to Marin Natural Resources Coordinator. 

Santiago finds meaning in their deep commitment to justice, equity, and envisioning brighter and more radical futures. Before CCNB they helped lead an environmental and racial justice based oral history project in the deep south of Alabama. They have also worked on urban farms, community gardens, program development for a food pantry, and was an official mediator for their college campus. In the future, they hope to attend grad school to become a professor or educator. When not at work Santiago enjoys reading, playing chess, surfing, rock climbing, and living in their community cooperative in Oakland.
