A&D Sprinklers, Inc., a San Diego-based fire protection company, has been acquired by Alabama’s The Hiller Co., another fire protection corporation. The acquisition closed on Nov. 1, 2020.

“The strong presence and solid reputation of A&D in their markets will be a great asset and will allow us to expand our fire protection offerings on the West Coast of the United States,” said Patrick Lynch, Hiller president and CEO.

A&D Fire Sprinkles has offices in San Diego and Los Angeles, Salt Lake City, Utah, and Spokane, Washington. Hiller plans to maintain all of A&D’s 400 management, staff and technicians.
