Service/repair shop near Beverly Hill area of Los Angeles

Hi All,
I need recommendation for a Apple Certified repair shop near the Beverly Hills area of LA. I’m the IT manager for company based in North Carolina. We have a small branch office in LA. From time to time there are issues that I cannot fix remotely nor can they wait till for me to come out and repair. I had one repair shop that I use to call on, but they have dropped the ball one too many times. So now I am looking for a new place. Does anyone have any suggestions?

TIA
Henry
