Locally owned and operated, ADA employs over 200 professional employees that work in one of our four businesses. Founded in 1996, James G. Murphy had a vision to deliver quality, hard working, local employees to the construction industry. Since then the business has grown to include security, sales, and investigation. To this day we take pride in our work, follow professional standards, and are fully licensed, certified, and insured. Safety is always our number one goal!
