Meet Our Natural Resources Team

Megan Meder

Megan Meder

Director of Natural Resources

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 continued to grow as a leader in the roles of Sonoma Natural Resources Coordinator, Senior Coordinator, and Sonoma Natural Resources Manager before being promoted to Director of Natural Resources in June 2022.

Greg Sitter

Sonoma Natural Resources Manager

Greg joined CCNB in February of 2020 with a diverse set of professional experiences. He worked as an Green Building Engineer in his native France before becoming a Volunteer Corps Member at an international non-profit called ATD Fourth World. During his 6 years tenure at ATD Fourth World, Greg collaborated with governmental figures in France to craft legislature to improve the lives of those living in persistent poverty. When the chance arose to continue working with ATD Fourth World in the United States, Greg moved to New Orleans where he ran street library programs making books and artistic activities accessible to children and families living in under-resourced neighborhoods.

Since moving to Sonoma County in 2017, Greg’s career has shifted towards natural resources management; Greg has designed, installed, and maintained school gardens and worked as an arborist, tree climber and foreman for local tree services.

In 2020 – 2021, Greg was the Sonoma Natural Resources Coordinator and then the Senior Natural Resources Coordinator for the NRC Department. In January of 2022, Greg decided to part ways with CCNB and worked as a Vegetation Program Manager for Pacific Gas and Electric in Sonoma County. Greg couldn’t stay away for too long and he returned to the CCNB team in September of 2022 as the Sonoma Natural Resources Manager.

In his spare time, Greg enjoys spending time with his family, gardening, beekeeping, tending to his flock of chickens, and competing in epee fencing.

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.

Casey has spent the majority of his professional career managing and facilitating operational logistics, and supply chain management.

Casey graduated from Cal Poly Humboldt in 2015 with a Bachelor of Arts in Environmental Studies, specializing in Natural Resource Management and Protection, and Environmental Policy. His senior thesis explored the intersectionality of natural disasters and disenfranchised populations, utilizing a case study on the lasting impacts which persisted following Hurricane Katrina. Most recently, Casey completed his post baccalaureate studies online from Vermont Law School, graduating with a Masters in Environmental Law and Policy. Casey specializes in Water Resource Management, Conservation Biology, and Climate Change Adaptation.

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.
