      Super! I highly recommend Corwin and his crew.
      We needed protection from vandals entering and damaging our SF property until we were able to erect secure fencing.
      Here’s what they did for us:
      1) Corwin kindly and happily (he’s a happy guy) informed us about their business history, legally required permit, security patrol cars and guards.
      2) They responded to our need the VERY DAY of the emergency.
      3) Provided 7 nights of 12 hour – onsite security from 7pm-7am, with a flood light illuminating the area where the vandals had access. (They even went above and beyond this, with a very clear presence to any potential vandals.)
      4) Provided us with pictures at the start and end of each shift, giving us the confidence that the vandals had not gained access.
      5) Corwin communicated with us every single day, plus responded promptly to our questions.
      Yes… we recommend them to anyone needing personal and professional security service.
      Office Mgr, Terri
