John G. Muller is an outstanding attorney and C.P.A. He's been my accountant and business advisor (helping me with everything from the mundane to the highly complex) for over 25 years and has been a colleague in recent years in immigration law questions. John seems to have the entire IRS code in his head. It's astounding. Plus, he is one of the most accessible professionals I know. If he can't take your call right away (a rarity), you can be sure he'll be back to you within minutes. This guy defines the word "professional".
