The first farmworker clinic was founded in Delano in 1965, where nurses Peggy McGivern and Marion Moses treated farmworkers and their families. It was housed in two trailers and located at the National Farm Workers Association (NFWA) strike headquarters at Arroyo Camp, on Mettler Road. In 1967, when the National Farm Worker Service Center (NFWCS) purchased a 40-acres parcel on Garces Highway and the Arroyo Camp was shut down, the two trailers were relocated at Forty Acres, the new union’s headquarters (by then called the United Farm Worker Organizing Committee, UFWOC). In 1970 Richard Chávez, César Chávez’s brother, started directing the construction works for a permanent structure. Built by a group of volunteers and finished with brick walls and a mission-style roof, the clinic was named in memory of Roger Terronez, a leader of the NFWA killed in a car accident in 1968. The Roger Terronez clinic opened in later 1971.
