The Nature Conservancy in Virginia announced today that Rebecca Rubin, longtime resident of Fredericksburg, has joined its state chapter as the newest member of its board of trustees. Rubin is the founder, president and CEO of Marstel-Day, LLC, an international natural resources and environmental consulting company based in Fredericksburg.

“After moving here from New York, I fell deeply in love with the lush green landscape that Virginia offers its residents and visitors,” says Rubin. “I am aware that The Nature Conservancy has conserved more than 300,000 acres of critical lands in Virginia by applying sound science and evidence-based decision-making to achieve results on a massive scale, and I am honored to have the opportunity to work with such a strategically-oriented organization.”

Rebecca Rubin

Rubin brings with her 25+ years of experience in the environmental sector. Prior to founding Marstel-Day, Rubin served as Director of the Army’s Environmental Policy Institute and was a member of the professional research staff at the not-for-profit Institute for Defense Analyses.

She was named by President Obama as a White House Champion of Change for Community Resilience and received the 2018 B’nai B’rith Humanitarian Award for environmental resiliency. She currently serves on the general board of Virginia Forever, which advocates for increased funding for water quality improvements and land conservation across the Commonwealth. She also served on the Commonwealth of Virginia’s State Air Pollution Control Board by appointment of the Governor (2014–2018) and is the immediate past Board Chair for the National Wildlife Refuge Association (2015-2019).

“We could not be more thrilled to have Rebecca join our all-star team here in Virginia,” says Locke Ogens, state director of The Nature Conservancy in Virginia. “Rebecca’s experience and expertise in the environmental sector will enable our state chapter to accomplish things larger than ever before.” 

Rubin’s particular interests lie in the urgency of both land conservation and the environmental education of the next generation.

“It’s really the creation of a conservation mosaic that is the pivot point for Virginia,” says Rubin. “We’re either going to get this right and preserve large landscape, or we’re not, and be left with only habitat fragmentation. Building on The Nature Conservancy’s accomplishments to date, we need to continue to create the conservation mosaic in Virginia in the right way, knitting together water resources, air quality, and the preservation of wildlife and habitat.”

Rubin earned her BA in History from Harvard College (1987) and her MA in International Security Policy from Columbia University’s School of International and Public Affairs (1991). Originally from Westchester County, New York, she lives in Fredericksburg with her husband, H. Lee Halterman. She has a 7-year old daughter, Cadence, and 2 stepchildren, Alex and Kimiko.

Rubin is especially excited by The Nature Conservancy’s ongoing efforts to connect families and, particularly, children with nature, which ties back directly to a commitment to land protection. “Over the long term, providing children with access to nature has to be elevated to become a key priority for the Commonwealth. We can’t provide generations of children with access to nature unless it is permanently preserved.”
