Over the past seven years, Nan and Jeanie have become fast friends, as well as partners in volunteering for Friends in many capacities. They’ve been Citizen Stewards at their Cousins Island site.  They also frequently visit the South Portland office of Friends of Casco Bay to help assemble membership mailings. True to their upbeat nature, they don’t regard the hours of folding, stuffing, and stamping solicitation letters as tedious. They both agree, “It’s not about the envelopes; it’s that we get to sit around the table and share stories with other volunteers who care about the environment. It’s another way we feel connected to the Bay.”

The women view their work as citizen scientists for Friends of Casco Bay as payback. Nan remarks, “I grew up boating, swimming, and eating seafood, and I wanted to do something to protect the Bay.”

Join Nan, Jeanie, and 300 other Friends of Casco Bay volunteers.
