Quote from gmst:
I had Gelber in mind but I checked and they have an office in San Diego.

Latency doesn't matter equally to all the quant shops. E.g. there is one well respected quant shop located in Hawaii, missing its name it was discussed on ET last year or so.
Gelber is based in Chicago. They have a small office in LA to accommodate a few traders that moved out there. Gelber is NOT a quant shop.
