About Us

Mr. Robert Chapman was the original owner of the company in 1952, but the business had already made its mark in Pacoima history. In 1972 John Mitchell took over the company and operated the business retaining the ROBERT F CHAPMAN corporate name. 2010 marked the 50 year anniversary and was a significant milestone. In 2001 we opened our new building in Lancaster, California. 

We look forward to surmounting new obstacles, setting new goals, and taking on new challenges in the years ahead. ROBERT F CHAPMAN is committed to our clients, staff and community. Superior technology now has become a vehicle for ever improving efficiency.
