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.
