Santa Ana-based Universal Services of America has acquired RJWestmore Inc. in Los Angeles.

Universal Services provides security and janitorial services, and had $396 million in revenue for the year through June, a 20% year-over-year increase. It had 1,944 employees in Orange County as of June.

The company has been in partnership for more than 15 years with RJWestmore, a company that provides commercial building tenants with fire-safety training and emergency certification programs.

Universal Services has been providing such training through RJWestemore, covering nearly 400 million square feet of office space throughout the U.S.

The acquisition deal followed the death of RJWestmore founder, Robert Westmore, in August.

“After he passed, it was a natural progression to merge the companies and keep his life’s work going, as they provide a service that is essential to Universal’s business,” said Steve Jones, co-chief executive and chief operating officer of Universal Services. “The company … will be branded as the RJWestmore Training System by Universal Fire/Life Safety Services.”

No employee changes are expected, Jones said.
