Anyone talked to Dean from PSE?

Has anyone got a hold of Dean from PSE? I sent a set of Studio MK V amps in for repair over a year ago. I spoke to him quite a few times and he always told me he was just getting to them. Now over the last two months I have not been able to get a hold of him. His phone number was disconnected and sent to a new number. I get his answering machine every time I call. I leave messages every time but he has not got back to me. Did he go out of business?
