Our Security Agency has set out to be different from the competition. The goal of our company is not to be the largest company in the business. Our goal is strictly to provide a type service no other company presently provides. We will be available to the client 24 hours a day 7 days a week to address the clients every need. We have developed a 24-hour client dispatch center where a live body answers the phone every time it rings and ensures that all the client’s needs are meet. The founders saw that there was a huge need for a company that could not only provide the full range of security services, but also provide them to the client on a personal basis. Every client we take will receive the dispatch number. The general manager’s cell phone and home phone and the number to the on call supervisor’s cell as well this ensuring the client is able to contact the correct person he or she might need.

1) Available 24 hours/day – 7 days/week to address client needs;

2) Developed 24 hour Dispatch Center to answer phones live;

3) Full Contact List of Phone Numbers to include:

a. Top Management Home Phone and Cell Phone Numbers;

b. On-Call Supervisory Phone Number;

There will never be a reason that someone cannot be reached to address any client need. We saw that there was a huge need for a company that not only could provide a full range of security services, but also provide such service to the client on a personal basis! We guarantee our service.


The 21st Sentry Security management concept can be summarized in one phrase: (Teamwork and Immediate Response).

Our management represents a combined total of more than 22 years experience in the security industry, and we are dedicated to providing the highest quality security personnel available.

Strong management sees its direction as not only legal and ethical accountability, but also anticipation of change, whether planned or unexpected. We feel it is the extra effort, to discover and react to potential difficulties before they become major problems, which makes 21st Sentry unique.

The goal of 21st Sentry security is to provide a professional approach to the protection of our client’s property. Our relationship and immediate response is what sets 21st Sentry apart the rest.

A daily activity report is mandatory for every shift worked. All security officers employed by 21st Sentry, to include the officers assigned to your account posses an Unarmed Security Guard license issued by the State of Arizona. In order for the State of Arizona Department of Public Safety to issue an Unarmed Security Guard license, an individual must successfully complete the 8-hour pre-assignment training course and submit their fingerprints for the purpose of obtaining state and federal criminal background checks. Every 21st Sentry guard meets all of the Arizona State Legislature Statutes governing security guards.

The uniform supplied to our officers consists of black slacks and Tan shirts with badge, shoulder patches, and identification. A black jacket with patches and badge is worn during colder weather.
