History & Community Roots
Brentwood grew around the Long Island Rail Road corridor in the mid-19th century, when the area was associated with Thompson Station and Suffolk Station. In 1851, part of the community became known as Modern Times, an experimental settlement founded on reform-minded ideals.
By 1864, the community adopted the name Brentwood, generally understood to be a reference to Brentwood in Essex, England. In the 20th century, the nearby Pilgrim Psychiatric Center campus became one of the area’s defining institutions; parts of the former state property have since been repurposed for recreation and other public uses, including Brentwood State Park’s athletic facilities.
