Meet Our Natural Resources Team
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.
Leslie Scott
Natural Resources Partnerships and Projects Manager
Greg Sitter
Senior Manager of Natural Resources Partnerships and Projects
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.
Mariah Chastain
Natural Resources Site Manager, Sonoma County
Mariah joined the Natural Resources team at CCNB in the Spring of 2020 as a Sonoma NRC supervisor before becoming the Sonoma NRC Coordinator. She then worked at Sonoma County Regional Parks and was a Prescribed Fire Apprentice with Fire Forward and Audubon Canyon Ranch. She returned to CCNB as the FIRE Foundry Fuels Crew coordinator before moving in to her current position. Her dedication to helping individuals of underserved and underrepresented communities pulled her back into this role.
Mariah graduated from Sonoma State University in 2020 with a bachelor’s degree in Environmental Studies and Planning and a concentration in Conservation and Restoration. She grew up in El Dorado County and was born near her family’s traditional homelands of Yosemite. She has always been grounded in her love for the natural world and her Indigenous culture. She is passionate about creating a community that is a diverse, inclusive, and supportive environment, teaching folks about land stewardship and returning good fire to California as her ancestors once did.
