Looking for Nuendo 12 Dolby Atmos Room in California

Hi All, I’m working on a project in Toronto, and the client now doesn’t want to travel
from L.A. for the final Dolby Atmos review of a natural history film. I mean he doesn’t want to travel to the cold for the review. Is there any California post studios using Nuendo 12 that I could bring my final project to for the final mastering review?
I would need to be there in January.
Thanks in advance for any help.
