Laura Johnson, who is stepping down as president of the Massachusetts Audubon Society, always loved environmental work. After graduating from Harvard in the ’70s, Johnson went to New York University to pursue a degree in environmental law, but it was through her 16-year job with the Nature Conservancy that she became involved with Mass Audubon. “What struck me about Mass Audubon and has proven to be true, it’s an organization that really ties together conservation and education,” says Johnson, who was named president of the organization 14 years ago. “I really believe in the organizations that put emphasis on reaching people through education and reaching people through advocacy and policy.”
