History of Menlo Park
Menlo Park received its official name in 1854 when two Irishmen, Dennis J. Oliver and D. C. McGlynn, purchased 1,700 acres (some sources say it was 640 acres) bordering County Road, now El Camino Real, and built two houses with a common entrance.
MPHA is a registered 501(c)(3) non-profit organization made up entirely of volunteers. We were established in 1971 as an offshoot of the Friends of the Library.
