She has enjoyed running and biking along the NWB, its tributaries and the Anacostia since moving to the area in 2015.

Nora Swisher, Secretary

Melissa Schweisguth, Vice President

Nora Swisher, Secretary

 Nora moved to the north-eastern part of the NWB in 2021. She got involved with NNWB because of the tremendous impact of stormwater erosion, trash, and non-native invasives on the tributaries in her neighborhood. She has a varied background that includes science, education, and entrepreneurship. She is continuing to learn about composting, native plants, and water quality. Nora hopes to empower neighbors to improve our waterway from their own backyards. She joined the Board in 2022.

Nora Swisher, Secretary

 Rebecca has lived in Woodmoor since 2014, choosing the neighborhood because of its proximity to the dynamic natural beauty of the NW Branch. She, her husband, their two nature-loving boys and dog walk almost daily on the  trails, appreciating the belted kingfishers, spicebushes, sycamores, and moss-covered boulders immensely. Rebecca is a Maryland Master Naturalist and is leading the effort to create the Springsong Museum at  Burnt Mills.

Ben has enjoyed biking, hiking, spotting wildlife and coordinating cleanups along the Northwest Branch since moving to the area in 2013. When he's not in the woods or near the water, he works as an IT Business Analyst for a small grant management software company. He hopes to help  grow environmental stewardship in the lower NWB, especially in and around Hyattsville. He loves how the beautiful river and its adjoining trails and parks bring people from all walks of life together to enjoy the outdoors.

Greg lives in Hyattsville near the lower Northwest Branch. He has worked on a range of environmental issues since the mid-1980s, mostly at the local and state levels, in grassroots research, education, organizing and advocacy, and mostly in Maryland and the DC region but also in North Carolina. He’d like to help strengthen NNWB's ’ base in Prince George’s County, build relationships with other nonprofits and local and state decision makers, and  engage people in the critical work of building social, economic and environmental resilience to climate change and other stressors. He joined the Board in March 2025.

Lilantha Tennekoon

Lilantha Tennekoon

Lilantha Tennekoon

I am very interested in water issues in our watersheds and  believe I will be able to make a positive impact. Professionally, I work as a Water Resources Engineer and therefore am familiar with many of  the issues afflicting our local waterbodies as well as stormwater runoff. Furthermore, I live in the NorthWest Branch watershed and enjoy the many trails of stream regularly and would love to be an advocate for their improvement and sustainability. I joined the Board in 2025.

Scott Zillmer

Lilantha Tennekoon

Scott Zillmer

Scott has lived in two places along the upper Northwest Branch (Forest Knolls 2001–2006, Stonegate 2016–present), but is originally from  Wisconsin. He is the map editor for National Geographic. He enjoys doing trash cleanups, and literally stumbled upon the abandoned farm in  the woods behind his Stonegate house—leading to cleaning out the old farm dump, and becoming aware of the severe invasive plant problem. He is aiming to clear 300 acres of the NWB Recreational Park of massive  invasive vines, and to make a positive impact on the natural world. He joined the Board in 2024.
