Allow me to introduce one Mr. James Vollmer. He is a lovely human being, and affectionately referred to as Pops by myself and Bells, but above and beyond that, he's an exemplary and fastidious accountant. If you choose to use him for your personal or business accounting needs, you won't be disappointed.
