Siren Studios has been working with the ATF Private Security team for several years now. The experience has always been nothing but fantastic. The security firm is reliable, consistent and dependable. The guards are all very experienced but also incredibly amenable. They work well alongside both my team of staff and with the wide range of clients we have onsite each month. ATF responds promptly to booking requests and are flexible with payment terms. We do not hire any other guards at this time as we feel that ATF provides us with everything we need and have a genuine regard for our venue.
