H&S Protection Systems, Inc. was formed as a result of combining two well-known alarm companies. Established in 1959, Horgan Sales & Service, Inc. was a premier provider of electronic protection systems throughout central and northern Wisconsin. Sentra Protective Systems, Inc. had been providing quality protection systems in southeastern Wisconsin since 1998.

The two companies combined to form H&S on January 1, 2007. H&S remains locally owned and operated by Mike Horgan (Stevens Point Branch) and Steve Garritson (Pewaukee Branch).

The purpose of the merger was to streamline operations by utilizing the best attributes of each company, strengthen technical and business expertise, and improve geographical service coverage for our combined customer base.

Today, H&S Protection Systems continues to provide high quality security, access control, video surveillance, and fire alarm systems for industrial, commercial, and residential applications throughout all of Wisconsin.
