After working on our Team as our Director of Conservation Easements for more than a decade, Karen retired, only to return as a Board Member (and we are so happy she’s back with us). Following previous work in the higher education field, she brings with her years of experience gained from the land trust community, with a focus on the legal side of things. Married to her husband Ray for 50 years and mother to two children, Lori and Jay, you can often spot Karen cheering loudly for her four grandkids at soccer games, swim meets, track and field events, and choir concerts. When she’s not rooting on the sidelines, she’s holding out hope for her favorite Philly sports teams; we can always count on Karen to bring us the latest updates on the Phillies’ and the Eagles’ progress…or lack there of. One of Karen’s proudest accomplishments has been her education. After supporting her children through their educations, Karen began taking college courses at the age of 47, graduating some years later. She spends her evenings walking with friends through the neighborhood or tending to her garden.
