Clients serviced by Sentry Security of  St. Louis

Director and Chief of Security
Steris Corporation

Dave,  from the first time I met you in St. Louis, along with Dick and John Mueller, the owners of Sentry Security, I was impressed with the level of concern and “hands on” experience each of you displayed. Because of the excellent service I receive from both your office staff and plant guards, plus the development of a very cordial relationship with you, Dick, and John, I will continue to use Sentry Security in the future.

Security Director
Americas Center/ Dome at Americas Center

I would like to personally thank you and your entire staff for the outstanding job Sentry has done and continues to do for the Americas Center Dome at Americas Center.

Special Services Coordinator
City of Jennings

Sentry Security Agency has been providing security for the City of Jennings public parks for approximately two years. In that time we have received many positive remarks from residents of Jennings stating that they feel safer in our parks. The city of Jennings has also had a marked reduction in vandalism and other instances of crime. They are very professional and their presence in our parks makes the park a safer place.

Director of Enrollment Planning
Francis Howell School District

Sentry Security Agency has been providing our security service at Francis Howell School District for nearly ten years. Prior to Sentry coming aboard, our school district was in need of a professional, sharp looking security service. The district has been impressed with the appearance, attitude, and spirit of cooperation you security force projects on a daily basis. John Mueller’s personal attention and Sentry’s performance is certainly appreciated.

Building Administrator
Archdiocesan Pastoral Center

We have had the opportunity to use Sentry Security for the past three plus years and have been extremely satisfied with both the service and personnel you have provided. There have been occasions when we required extra service and personnel, it has always been provided. We are very pleased with the present, regular officer at our facility. He is most conscientious and courteous. I feel confident and secure having Sentry Security as a working partner.

General Manager
Watco Terminal and Port Services

After experiencing a very expensive loss due to break in at our facility, I contacted security alarm vendors in an attempt to improve the level of protection in our warehouse building. ACF Alarm responded to my call promptly. ACF’s partner, Sentry Security Agency provided us with a fixed security officer until the new security system was in place. During the whole process ACF and Sentry demonstrated professional layout/installation/system/training and on-site guard protection. I use Sentry to respond to alarm sounding situations so I or any other team members do not need to personally respond to the facility in the late night hours. Sentry and ACF keep me informed every step of the way and showed genuine interest in providing me with the level of protection I needed.
