Just as an addon to this post,
I done my training at PAT, got a first time past on my IRT. My training was excellent.
Anthony was the CFI at the time, he conducted my 170, which I felt was harder than the actual test itself. As a result I felt more prepared and a little bit more confident for the test.
No Sponsor I am not sure where you are coming from but every organisation has a turnover in staff, thats life. I am sure that the new instructors at PAT will be more than capable of maintaining the high standards acheived by previous incumbents, if Anthony has anything to do with it.
One thing I do subscribe that you should always visit a FTO before commiting financially.
