Mona Gill Electric Group


In early 2014 Mona Electric Group acquired employees and select assets of Gill-Simpson, Inc., (GSI), a prominent Baltimore electrical contractor, with an unsurpassed reputation for serving its private, institutional, and governmental clients. Founded in 1932, GSI excelled in providing quality industrial and commercial electrical services to its customer base, supported by their highly skilled electrical craftsmen and technical staff.

The addition of the Mona/Gill Group expands the strength and diversity of services that Mona has developed over nearly 50 years in business, and adds to Mona’s reputation as the Premier Electrical Contractor in the Washington/Baltimore Metropolitan Region.

Our 12,000 sq. ft. facility in Owings Mills, MD is conveniently located to support operations in the Baltimore market, ranging from Aberdeen to Frederick.

We add value by combining Low & Medium Voltage Power Construction with a local fully integrated Service and Maintenance group. Our staff of Estimators and Professional Engineers provide constructability review, “lessons learned” experience and cost input to maintain the project budget and schedule.
