There are a lot of spin offs in Simi, West-Lake and Valancia.
OK technically some of that is in Ventura county but it’s all part of the same general North-LA region.
I have worked in all three locals (also Arcadia).
I would add in L.A. a hour commute is considered reasonable LOL. I do know quite a few Amgen employees who live in Valencia and even Arcadia and Westwood.
