I "dealt" with JP sept-oct 2005 when I was there for a three-week PPL. But I only saw him once, I think, when I arrived at the school and he showed me around, went over the paperwork with me and such. I did not have any serious problems while being there, so I never needed to speak to him at any time.
I was there when the new chief pilot (Simon something) came on board and I found him a nice chap, easy to work with. The few problems I had were solved to my satisfaction, eventually, by him.
