We are an event venue that also does photo shoots, filming and small weddings. My usual Site Rep left me in a bind for security at a recent event. I saw all the great reviews on Yelp so decided to try Assertive Security for security. My dealings with them were great from beginning to end. We will certainly use them again!

Holy smokes. I’m a part of an HOA and we’ve had some trouble with a resident lately. We decided to take the next step and hire a security guard to keep all of our other residents safe until the issue is resolved. It was the best decision we made. Thank you Mark!!

Maryam has worked with us from day one to ensure that our changing needs have not only been met but exceeded as her experience allows her to anticipate future requirements.
I highly recommend Assertive to anyone looking for security services.
Marci C.
My building has had several break ins lately (2x for my car alone this year) and as you can imagine it has caused the tenants some angst. I spoke with someone named Miriam who immediately asked if I was ok – weird right? Instead of pitching her services she asked what she could do for me to make me feel for comfortable without forcing the companies services on me. Thank you!
Jeremy R.
Maryam and her team have been fantastic. We hired one security guard for night and we have since added 24 hour security because they have been so great! I’m the building manager for a office on the Hollywood strip, and Assertive Security has let us breath easy knowing they are here. Thank you so much Maryam for setting us up with amazing guards!
Ana E.
