Hi Jay,
I did my PPL at TG and would have no problem recommending them. Re: your question, do you mean "how many hours of instruction", or "how many months went by"? I'm not sure what you're hoping to measure by knowing those numbers, but in any case, I spread it over about three years, which meant I had to keep revising things due to long breaks without any flying, which meant I had about 50 hours when I finally took my skills test.
HTH,
Chris.
