Mark from Pittsburgh Pinball Repair has been my sole service agent now for quite some time. His technical ability to diagnose (often over the phone) and repair is second to none. His professionalism and dedication to satisfying his customer's needs are of greatest importance and yet he does all this in a relaxed and friendly manner. I have had no hesitation in recommending Mark and Pittsburgh Pinball Repair to my fellow pinball enthusiasts or anyone who finds themselves with a dilemma and need some advice or repair. If by some chance he doesn't know, he will tell you and through his long association with the industry he will find out! Now that's service. Minor or major pinball or arcade repair, Mark is the one for the job. No question about it.
