Our Story

In 1983, when gasoline averaged $1.16 per gallon, average monthly rent was $320, and the top tax bracket was 50%, the accounting firm of Pestine, Brinati, Gamer, Ltd. was founded.

Since then, the firm has expanded significantly, having created two affiliated entities to offer payroll processing and investment advisory services to its clients. In 2005, to express the company’s vision, the firm was rebranded PBG Financial Services Ltd.

The firm now has 50 employees with offices in downtown Chicago and Northbrook, Illinois. PBG takes great pride in the longevity of its client and staff relationships, which in some cases extend beyond twenty years.
