Sarah McGowan 

Sarah became a charter member of Friends of Holmes Run after years of working around the edges to improve her portion of the watershed as a conscientious homeowner, civic association leader, longterm volunteer, Invasive Management Area (IMA) site leader and parks instructor. The first part of her career focused on youth development and volunteerism, including 13 years working with underserved youth and the Corporation for National and Community Service. Many of the projects she organized for youth were environmentally focused and she has a special interest in plants (both edibles and natives). She is a Virginia Master Naturalist and Certified Interpreter, putting those skills to work at such sites as Riverbend Park where she served as a naturalist. Sarah also served on Raymondale Civic Association board, where she chaired the neighborhood's Environmental Stewardship Task Force focusing on protecting neighboring Holmes Run. 

Sarah sees Friends of Holmes Run as an opportunity to get kids excited about the wonderful wetland resources that are in their own backyard, with the hope that some of those kids will become future environmental stewards. Sarah has a degree in Anthropology and an MSW from the University of Notre Dame and Boston College respectively.

A resident of Mason District for 30 years, Lynn volunteers as an invasive species coordinator at Annandale Community Park/Hidden Oaks. She has a degree in Environmental Sciences. 

Whitney Redding (primary conservator)

Whitney came by her interest in the protection of the Holmes Run watershed as a homeowner who lives next to the Stream Valley and has observed many changes accelerated by the forces of urbanization and climate change over 20 years. Whitney’s vision in co-founding Friends of Holmes Run is to connect local property owners and civic groups who are motivated to protect the Holmes Run watershed but have no real knowledge on how to go about it, with experts who understand the challenges of the watershed on both a micro and macro scale. 

Whitney is the longtime president of Raymondale Civic Association where her focus has been on building community through shared environmental stewardship. She was a member of the countywide working group that created the county's first longterm plan to address climate change in Fairfax County (CECAP) and is a member of the Climate Resilience working group and Greener Mason Environmental Advisory Committee. Whitney’s professional background includes journalism, crisis communications and public relations for nonprofit organizations. She is a certified Virginia Master Naturalist and a volunteer Tree Rescue trainer for Fairfax County Park Authority.
