Boss Shepherd Society

Known as the “Father of Modern Washington,” Alexander Robey “Boss” Shepherd was an influential civic leader in Washington, D.C.’s history. As Governor of the District of Columbia from 1873 to 1874, Shepherd oversaw the planting of more than 60,000 trees across the District. With his vision, he pioneered the city’s significant increase in green space, earning it the nickname the “City of Trees.”

The Boss Shepherd Society is an exclusive network of donors who have contributed major gifts of $5,000 or more. Members of the Boss Shepherd Society lead the way in strengthening the green legacy of our nation’s capital and its surrounding counties, ensuring that Washington, D.C. remains the “City of Trees” going forward.

If you’d like to make a gift of $5,000 or more, please contact the Development department directly at 202.349.1894.
