Gilead Sciences Inc., a major pharmaceutical company, will establish a 23-acre campus in La Verne that will employ 500 people, extend Wheeler Avenue to Puddingstone Drive and conduct research for cures and improved treatment techniques for significant diseases. The scientific and medical research company committed to advancing therapeutics which improve lives will relocate from San Dimas to La Verne and take over a 23-acre parcel in the industrial and manufacturing zone in La Verne's southern quadrant, noted La Verne Senior Planner Eric Scherer during a recent La Verne City Council meeting.
