The Trim FamilyAbout Us

Pennington & Trim is proud to be one of the largest alarm companies in Central Mississippi. Located in Flowood, Mississippi, we are locally owned and operated. The majority of our work is in Hinds, Madison, and Rankin counties.

We are a Christian company. We bring the tithe of every single dollar this company makes to the local church. We also support missions around the world. Our ultimate goal is to make money to help spread the gospel.

Company History

Pennington & Trim Alarm Services, Inc. was founded in the fall of 1987 as a partnership between Norman Pennington and Ed Trim. In the early days, the work was done out of Ed Trim's house using his storage room as a stock room. Slowly, the company began to grow, and more space was needed. A small room in the back of a building was rented in 1988 at 4374 Mangum Drive from the Southern Electric Corporation. Later, the entire back of the building was leased. In 1991, Dana Trim (wife of Ed) quit her job with an insurance company and became the first office personnel as she performed accounting duties for the company full time. Eventually, the entire building was leased when Southern Electric built their new offices next door. A few years later, the old building was purchased as well as the land in front of it on which the new building was constructed. The company has grown tremendously over the years.

"We have truly been blessed with great customers referring us to their friends, relatives and neighbors. We've been blessed with great builders that call us every time they need a security system installed in a new house under construction. We have been fortunate enough to accumulate over 12,000 customers in the Hinds, Madison and Rankin counties. We are one of the larger alarm companies in Central Mississippi. However, we still remember that little small room where it all started back in 1987 and all the hard work it took us to get to this point."
