The Corey Brewer Foundation is focused on preventing diabetes and improving the lives of people who have already been affected by the disease. Corey has been getting tested for the disease since he was a teenager. Both of his parents and the majority of his family members have either Type 1 or Type 2 diabetes.

Since joining the NBA, Corey has worked with schools in Tennessee, the Juvenile Diabetes Foundation in Minneapolis, Shands Hospital in Gainesville and with a number of other organizations to raise awareness. The Corey Brewer Foundation is in the process of expanding its reach to provide testing and education for at risk youth with unhealthy lifestyles.
