Board of Directors
Founder / Chief Executive Officer
Raised as a teen in Belgium and educated at the University of London, Marc Johnson was a potter and an art teacher with a studio in Cambridge, Massachusetts when, in the early 1980’s, he answered an ad and bought his first parrot, a blue and gold macaw named Wally. As fate would have it, on the very same day he bought Wally, he rescued his first parrot, “Bill”, an unwanted mitred conure. The relationship he formed with these birds in the early 1980’s lead him down the path he still walks today as the founder and CEO of Foster Parrots, Ltd. Marc’s drive and dedication to parrot protection and avian welfare issues have brought him before audiences across the country to speak on topics including the captive parrot crisis, wild parrot conservation efforts in South America, and controversy surrounding non-native parrot species in the U.S.

Susan Sheridan, MSW, since 2007
A dedicated psychotherapist in practice with humans, Susan Sheridan’s spiritual journey on behalf of captive parrots began over 20 years ago with one very special cockatoo named Jules, who captured her heart and soul, and gradually brought her to understand how challenging it was for him, every day, to repress his wild nature and conform to life as “a pet” – even though he was treated like “a prince”. Susan’s search for a better life for Jules led her to Foster Parrots many years ago and inspired her quest to ensure that other wild spirits like Jules would have a place to go. Her dedication to the future for difficult cases like Jules has resulted in the establishment of the New England Exotic Wildlife Sanctuary.
Susan has been an animal enthusiast and advocate “forever”, and for over ten years has been involved with the Wildlife Conservation Society as well as with Foster Parrots, supporting programs as close as the Bronx, New York and as far as Gabon, Africa.
