PanAM, FSI, ATP, AriBen, DCA, ERAU, MTSU, UND, CPS, White, Mom & Pop FBO's, any intermediate flight training school, or university flight program, etc...
They all will have at least one good CFI.
Are you looking for a larger school or a more intimate one? 141 or 61? Training for personal or professional advancement? Single or twin training? Are you self-motivated or do you prefer a structured, step by step, learning environment with classes? Where do you want to be in 1 year, 2 years, 5 years, etc?
Lot's of questions to answer... but it really does boil down to what school feels right for you and your needs. So... start figuring out what your needs are and then start making phone calls and go on a flight school touring spree. It will really open your eyes.
That said... a good CFI is all it really takes.
