Our Story

The commercial security system industry needed true customer service. JMG delivered.

In 1987, both Ken Jacobs and Mike Christensen left executive positions with large commercial alarm companies to find a better way to provide excellent customer service in their industry. From humble beginnings in a garage, they identified a market in serious need of a higher level of customer service and support than had ever previously existed.

Security system companies have long been known for their poor customer service and both Ken and Mike decided the time was right to demonstrate what true service excellence can be when providing security systems for businesses. More than 35 years later, JMG SECURITY SYSTEMS is now the premier business security systems consultant and installer for Southern California companies and remains committed to providing the excellent service its reputation was founded on.

JMG’s offering of commercial security systems combines the latest cutting edge technology with expert and custom tailored solutions to businesses across Southern California who are looking to install or upgrade their commercial security systems. The brilliant staff that have supported this vision for over 35 years are at the heart of what makes JMG SECURITY SYSTEMS such a reliable, service-oriented company and what drives the positive culture that Ken and Mike are still so proud of.

Our first class team provides excellent customer service and our clients keep coming back.

To deliver ‘Best-in-Class’ commercial security systems, customer service is what drives us each and every day.

The JMG family has grown heavily from within and any outside talent that joins us often shares similar feelings, “I have never worked at a company where every single person is equally dedicated to best-in-class customer service!”
