Staff & Board


The staff and volunteer leadership at the American Cancer Society Cancer Action Network are dedicated to leveraging the power of government to end suffering and death from cancer. Our diverse background and experiences help us set the direction for the incredibly successful initiatives we're conducting at every level of government.  We are immensely grateful for the cancer-fighting work our staff and, most importantly, our volunteers do every day in Washington, DC and in over 100 communities across the country.
