Simpson's
Simpson's Family Barber Shop
1181 El Camino Real
One of 5 small shops in a building built in 1937, originally this space occupied by Pacific Grayhound Lines.
Simpson opened his barber shop in 1940.[1. The next owner, Joe Valvarde, cut hair into the '70s or '80s (beginning date?).[2]
When the SF 49ers were training at Menlo College ('46-'54), some of the players would get their hair cut at Simpson's.[2]
