Mark joined Potomac Riverkeeper Network in 2015 as the official Shenandoah Riverkeeper. Having guided on the Shenandoah and Potomac for almost twenty years, Mark Frondorf comes to the Shenandoah Riverkeeper position used to hard work and recognizing the importance of a hands-on approach to protecting our rivers. His passion for the water, combined with his people and analytical skills, honed over 25 years as a think tank senior policy analyst tackling some of the most vexing issues facing our nation, make him ideally suited to defend the Shenandoah against pollution, protect our right to clean water, and promote the recreational use of this beautiful river. Mark was the principal investigator and author of a government study that examined the ocean dumping of U.S. chemical weapons and explored the full-range of issues, challenges and potential solutions to this complex problem.

As the former president of the Potomac River Smallmouth Club, he successfully lobbied both Virginia and Maryland officials to implement and expand catch and release regulations and he was instrumental in getting the federal government to revise the Code of Federal Regulations to permit wade fishing on portions of the Potomac. Mark also served on the Board of Directors for the Mid-Atlantic Federation of Fly Fishers. He holds an M.A. from the George Washington University Elliott School of International Affairs.

Jeff Kelble stepped out of his fishing guide raft and into conservation work in 2005 when he started and became the Shenandoah Riverkeeper.  Before he became Shenandoah Riverkeeper, he worked for 8 years to build a private smallmouth bass guiding business and a bed and breakfast which he ran with his wife Erika. It was after years of fish kills which devastated the Shenandoah River’s fishery that Jeff decided to put down his oars to join the fight for the river and its health.  In 2014, Jeff transitioned from fighting pollution and protecting public use of the rivers to become president of Potomac Riverkeeper Network.

As Riverkeeper Jeff focused on investigating fish health problems and quickly became a regional expert and advocate. Jeff spent years scouring the river and the land for pollution sources and fighting to stop pollution with community action and legal enforcement.  Now Jeff works to create an environment and direction at Potomac Riverkeeper Network where his Riverkeepers and program staff are supported and can devote all of their time and energy to the river.

Jeff served as Conservation Chairman, Newsletter Editor, Vice President and President of the Potomac River Smallmouth Club, was a founding board member of Earthkorps, and serves as Secretary of his daughters’ school board. He holds a Bachelor of Science in Human Factors Engineering from Tufts University.

Prior to joining Potomac Riverkeeper Network, Phillip was the Hudson River Program Director at Riverkeeper in New York for nearly ten years, leading efforts to reduce sewage pollution, clean up historic industrial sites and bring enforcement actions to protect the Hudson River. During his tenure as Director, Hudson Riverkeeper brought successful actions against dozens of polluters, including ExxonMobil for its historic Greenpoint oil spill and numerous concrete companies, scrapyards and other waterfront sites whose operations violated the Clean Water Act. Phillip also worked to ensure passage of a New York state law requiring public notification of sewage discharges, and served as a citizen advisor on two task forces convened by Mayor Bloomberg to address climate resiliency challenges in New York City in the wake of Hurricane Sandy.

Phillip received a J.D. with honors from Pace University School of Law, and a B.A. (magna cum laude) in Geography from the University of Washington.
