Why Partner With Friends of Casco Bay?

Casco Bay is the environmental, economic, and cultural heart of our region. Unfortunately, scientific data show troubling changes ahead for our coastal waters. By becoming a Corporate Partner with our organization, you are investing in the science and community engagement efforts necessary to improve and protect Casco Bay.


Friends of Casco Bay improves and protects the environmental health of Casco Bay. As home to the Casco BAYKEEPER® we act as the eyes, ears, and voice of the Bay. Our integrated, community-oriented approach is continuing to move the needle for a healthier Bay.


The options to be a corporate partner are laid out in the overview of Friends of Casco Bay’s Corporate Partner Program here. We look forward to a conversation to discuss these options and how our values and work align.
