Kenny Mendez, Director

Kenny has been in Washington, DC for 25 years working for environmental and healthcare nonprofits.  An avid fly fisherman, Kenny loves the Potomac. He frequently fishes and kayaks the river with his wife and three sons. His passion for angling led him to nonprofits. He left the Consumer Products Division of the Walt Disney Company in Los Angeles to be Chief Operating Officer at Trout Unlimited. While at TU, Kenny helped the organization grow from 57,000 to 157,000 members. His life centered around building his family, conservation, and fishing on TU business trips. When his wife suggested Kenny get “a real job,” he accepted an offer to be Chief Administrative Officer at the Advanced Medical Technology Association (“AdvaMed”) where he learned about healthcare, ran business operations, strategic planning, and pursued new revenue initiatives for the organization. With his lifeline to regular fishing trips gone, Kenny spent much of his free time on the Potomac in a rowboat at Fletcher’s Cove fishing for shad, striped bass, smallmouth bass, and gar. During one of his fishing outings he witnessed a Potomac Conservancy river cleanup and became instantly sold on Potomac Conservancy and its work.

Kenny is currently President and CEO of the Asthma and Allergy Foundation of America. He has an MBA from Columbia Business School and an A.B. in American History and American Art from Harvard College. He currently serves on the board of the Trout and Salmon Foundation and volunteers with Friends of Fletcher’s Cove.
