The Levee Singers brought back wonderful memories for Dallas's finest. The Levee Singers called on the whole crowd to sing along, to clap their hands, and stomp their feet as they harmonized to songs of American pride. Guests also learned about research led by Dr. Karl Csaky, T. Boone Pickens Senior Scientist, who is working to develop a novel drug delivery device that has the potential to treat all forms of age-related macular degeneration. "A Fun Evening with The Levee Singers" strengthens our efforts to continue leading research that is saving sight.
