Tammy Severino | President & CEO

Tammy Severino is the President & CEO of Girl Scouts of Suffolk County, the largest girl-serving organization in the county. A former member of the Council’s Board of Directors, troop leader, and Girl Scout herself, Tammy comes to her role with an understanding of the organization’s strengths and a passion for the mission of serving the girls and adult volunteers of Suffolk County. Her pursuit of opportunities for girls to develop and grow is what Ms. Severino hopes will define her tenure with the Council.

She serves as a business mentor and coach for professionals, particularly those ‘stuck’ in their positions or looking for significant change. Tammy has served in leadership positions for nonprofit organizations, where her strategy, Board development, and fundraising skills resulted in ongoing growth.

For her efforts in the nonprofit and business communities, Tammy has been recognized as a two-time winner of Long Island Business News’ Top 50 Women in Business, a recipient of the 2019 Angel Award winner from the Equity First Foundation, a two-time recipient of the President’s Award from Girl Scouts of Suffolk County, winner of the Fortune 52 Award from Long Island Press, Top 40 Under 40 from Long Island Business News, and the Chairman’s Award from the Association of Fundraising Professionals of Long Island. In 2022 Tammy was named to Long Island Press' Power List for her work with Girl Scouts of Suffolk County.
