J. Manly Parks, Board Member

Partner, Duane Morris LLP

A native of historic Chestertown on the banks of the Chester River on Maryland’s Eastern Shore, Manly has had a lifelong love for the water. Following his education at Woodberry Forest School near Charlottesville, Virginia, where he spent his free time fishing and exploring the Rapidan River, at Colgate University, where he fished the Chenango River and spent thousands of hours on the water of Lake Moraine as a member of the crew team, and the College of William & Mary Marshall-Wythe School of Law, where he coached freshman undergraduate rowers, he moved to Philadelphia in 1994 to practice law.

Since 1999 he has resided in Delaware County. He is a partner with Duane Morris LLP in Philadelphia where his law practice includes antitrust, franchise and distribution law, and general complex commercial litigation. Active in state and local politics, Manly is a former township commissioner in Nether Providence Township and Solicitor of the Delaware County Board of Elections. An avid fisherman who loves nothing more than “simply messing about in boats,” Manly watched his native Chesapeake Bay and its people struggle through the challenges of population growth, pollution, collapsing fisheries and the ways of life they formerly sustained.

He brings his love of the water and deep commitment to the mission of the preservation and recovery of the great and historic waterways of America to Schuylkill River Greenways, where he is inspired by the opportunity to contribute actively to the ongoing efforts to protect and improve the Schuylkill.
