Guardian Alarm, a large full-service residential and commercial security services company in the Midwest, has completed the acquisition of Columbus, Ohio-based SDG Security.

SDG Security was founded in 1986 as Sound Design Group by Bruce Reedy and Steve McCullum. Since its inception, the company has specialized in custom designed security, communications and sound systems. Due to the rapid growth of its monitored security systems, the company soon established its own central station staffed with SDG personnel, according to the company’s website.

“For years, the SDG Security team has been proudly serving and protecting the Columbus community, ensuring our customers stay safe and secure,” said Reedy. “Given Guardian Alarm’s commitment to customer excellence and innovation, I am confident they will continue our tradition of protection and superior service.”

Since 1930, Guardian Alarm has been a recognized leader in security and fire alarm services, serving both commercial and residential customers across Michigan and Ohio. With an existing branch location in Columbus, the SDG acquisition will serve to strengthen the company’s footprint in the market, enabling Guardian Alarm to bring its security services to more Columbus households and businesses.

“SDG Security plays an important role in the community and in the lives of their customers. We are excited to welcome SDG’s customers to the Guardian Alarm family,” said Brent Uhl, president and CEO of Southfield, Mich.-based Guardian Alarm. “Through our combined companies, we will continue to provide an exceptional customer experience while offering both existing and future customers a broader portfolio of innovative security and fire alarm solutions.”
