"The Blazers are the competitive teams of the BlazeSports Georgia program. The teams compete locally, regionally and nationally in swimming, wheelchair basketball, and track and field. These talented young boys and girls are winning medals, breaking national and international records, and developing into superb athletes.
The teams are supported by the BlazeSports Georgia Booster Club, composed of parents and others interested in seeing that the teams have the resources and equipment to travel and compete effectively in their sports."
