Typically, GFE means = DFK, BBBJ, DATY, MPCFS, FIV, MSOG, IOP (Important!) for PSE, add in Greek, COF/COT (This is debatable can go either GFE/PSE) .

Most important thing about providers that do GFE, and do it very well, is the IOP and feeling refreshed afterwards. Not having an ounce of regret from seeing them or feeling rushed is important.
