United Blood Services California relies on volunteer donors to meet the blood needs of patients in Los Angeles, the southern end of Ventura County, and as far north as Salinas, including Santa Barbara, Santa Maria, and San Luis Obispo. According to America's Blood Centers, fewer than 10 percent of eligible donors give annually. When you give blood at least 3 times a year, you qualify as Gold-level donor, receiving special recognition through our Hero Rewards program. Visit http://www.UnitedBloodServices.org to learn more.
