It is one of the largest high schools in New York State, on the southern shore of Suffolk County, Long Island.History1951-1970The first class to graduate from Brentwood High School was the class of 1957. Prior to this, public school students in the district attended Bay Shore High School.Brentwood High School began with the Ross Building, with its tennis courts and state of the art swimming pool. It was named for William H. Ross, M.D., psychiatrist, founder in 1898 of the Ross Health Resort (now Ross Healthcare, still located on Suffolk Avenue).The Sonderling Building was completed and open for students in September 1964.The first senior class to graduate in Brentwood was the graduating class of June 1965.During the summer of 1968, temporary portable classrooms were constructed between the Ross and Sonderling Buildings, housing the language and health classes. The Guy di Pietro Building was later constructed in between the two main buildings and named in honor of the late Social Studies Department Chairman, who became the Superintendent of Schools in 1966, and remained so until his death.On January 11, 1968, then-Senator Robert F. Kennedy visited the Brentwood High School and spoke to 800+ students, parents and faculty in the Sonderling auditorium. After giving a short address, he opened the floor to questions and asked his own questions of the audience.In the autumn of 1968, more than half the female students staged a Dress Code protest. They wore pants. So many were sent to the office (then run by the sole principal, Stanley P. Yankowski), by their classroom teachers, that the Dress Code was changed.
