I'd have to say Lisa McCormick for all her great lessons and re-kindling my interest in acoustic guitar. I love her finger-picking lessons! Really, worth the price of admission right there. Definitely a big "I'm grateful for..." to Christopher and the other guitar tricks instructors who tirelessly respond to people's questions on the forum as well as giving great lessons.

I'm also grateful for the instant cure for carpal tunnel syndrome... they're coming out with that soon, right?
