As a diabetic, Yamin supports and works as a spokesman for various organizations, including the Juvenile Diabetes Research Foundation (JDRF). In October 2006, Yamin sang the national anthem at the Dodger Stadium (LA) and cut the ribbon during the JDRF International Walk to Cure Diabetes. In addition, a portion of the proceeds from his Virginia State Fair concert benefitted the JDRF. The Central Virginia Chapter of the JDRF honored Yamin for his commitment to diabetes awareness and research at its 8th Annual Spring Gala on March 1, 2008; more than $400,000 was raised at the event. He returned for the 9th Annual Spring Gala on April 4, 2009.
