Every 2 seconds someone in the U.S. needs blood. Having enough blood on hand during June, July and August is difficult when fewer donors schedule appointments because of vacations and other summer activity conflicts. On average 700 fewer blood drives are held during the week of the 4th of July. Please consider donating at the Centerville Community Center on Friday, July 6th, 2018. Each donation can help save up to 3 lives. There is no substitute for blood.
