Sustained energy. Making time to give back Clif bar has been sustaining athletes at all levels since 1992, and we're just as proud to sustain communities across the country. Since we established our Clif corps program in 2001, Clif Bar employees have dedicated nearly 175,000 hours to delivering meals to the elderly, building trails and urban gardens, cleaning beaches, volunteering at local schools, and more-all on company time a lot goes into making Clif bar & company such a special place to work, and serving others has always been one of our favorite ways to give back.
