I have worked in the security field for over 15 year. I have always loved the work. I was hired by Area Manager Heather Yeske. She is the best supervisors I have ever had. This company is one of the best security companies I have the pleasure of working for.

I have used this company for years with great satisfaction. The contract and pay is only as good as the client dictates. Their response to my needs are always timely and professional. I highly recommend them. Brooke runs a tight ship there

I have worked for American Security for 7 years and continue to do so on a part time basis. I have found that you get out what you put into it and I have been treated very fairly by all of the supervisors there.

Not a good place to work for, my husband got bashed for being in the ER due to him having chest pains, he has heart problems and Dan got into my husbands face saying he can't have my husband have chest pains or heart problems. My husband can't help it. So Dan said to my husband either stop having chest pains or leave. So my husband left. So you have to be Dan's favorite AND perfect to work for him.
