46. Yvonne Grant

With headquarters in Commack, several satellite locations across the county, two summer camps and dozens of employees, the Girl Scouts is famous for more than just cookies: As the state’s largest council, it serves more than 43,000 Suffolk County girls. Grant, a former troop leader, has been helping to grow the organization for almost 30 years, working her way up the ranks while holding just about every job possible. From teaching environmental conscientiousness to fitness awareness to creating the annual holiday light show, she continues to be a driving force behind the Girl Scouts of Suffolk, while molding the leaders of tomorrow, one cookie box sale at a time.
