Green City Challenge Board of Directors

Les Judd,  Founder and President

Mr. Judd has been an environmental activist and leader all his life. He was inspired to be an environmentalist during childhood when he participated in a clean-up of the local brook in Ossining, NY where he grew up. Les became a leader in the nuclear freeze movement in 1982 when his Rabbi recommended him as a co-founder of the local nuclear freeze chapter. During the 1990s, Les was an activist and leader in the Sierra Club. In 1995, Les was one of the founding members of the Environmental Committee at Congregation B’nai Jeshurun on the Upper West Side of Manhattan. He served 5 years as Co-Chair and is still active on the committee. Les was a volunteer hike and urban walking tour leader for Mosaic Outdoor Mountain Club of Greater NY for many years. Les believes that one of the best ways to be an environmentalist is to be a vegetarian or vegan.

Les has professional experience in New York City government, the private, non-profit sector and in private business. Les is an Adjunct Professor at Lehman College in the Bronx and teaches two undergraduate level courses on environmental sustainability. Les has an MPA from New York University and a BA from SUNY Brockport.
