Five months ago, Brian McMahon did handyman-like things as a hobby. Then everything changed at the end of August when he âtook overâ his aunt and uncleâs business â Ace Handyman Services. The company serves the south Pittsburgh area. McMahon, long an entrepreneurial spirit, is a full-time businessman with a base in Monongahela and craftsmen in Washington, Donora and Monongahela. â(Being a handyman) myself is still a hobby,â McMahon said. âI do things at home and I do some other stuff. As for our business, I allow and count on our craftsmen to do the work they are skilled in doing.â
