About Search Results

YP - The Real Yellow PagesSM - helps you find the right local businesses to meet your specific needs. Search results are sorted by a combination of factors to give you a set of choices in response to your search criteria. These factors are similar to those you might use to determine which business to select from a local Yellow Pages directory, including proximity to where you are searching, expertise in the specific services or products you need, and comprehensive business information to help evaluate a business's suitability for you. “Preferred” listings, or those with featured website buttons, indicate YP advertisers who directly provide information about their businesses to help consumers make more informed buying decisions. YP advertisers receive higher placement in the default ordering of search results and may appear in sponsored listings on the top, side, or bottom of the search results page.

Advanced Professional Security
Steve S. rated

They lie to get you to work for them. If and when you leave they don't want to pay you. They advertise for law enforcement or military. One of their so called supervisors came directly out of walmart. The Owner Galen is a joke. You call to discuss anything, Susan Cobb (Office Manager ) hangs up on you. Check out recent reviewsThey're non-professional. They just want bodies. Stay away. I learned the hard way.

West Metro Security
Wyatt H. rated

Basically this company boots cars for $100.00 cash. They are in the business of ruining people's day for profit. In my experience, I parked at a lot which I thought was for the light rail and it ended up being private which is my mistake. However, my car was booted, a sticker was placed on the window and I had to wait a total of 3 hrs for someone to release my car over a span of two days. The crime does not fit the punishment. This "business" made them the priority and did not care what my scheduled was. This company is a pure scam and I hope a business thinks twice before hiring them.

JCJ National Security
Leroy G. rated

JCJ does a phenomenal job a protecting assets and covering all liabilities at every event they are contracted for as well as they are great in customer service. Reasonable in pricing and easy to communicate.
