Rob was raised in Norridge, which along with Harwood Heights is the only suburb of Chicago located entirely within the borders of the city. Long referred to as "the island in the city," Rob has been active in this community his entire life and was raised in a family that valued civic and political involvement.

Rob has 16 years of experience in local government. In 1993, while still in law school, Rob ran for the post of Trustee to Norwood Park Township, a post in which he remained for one four year term. During that term, Norwood Park Township had balanced budgets for four straight years and reduced its number of employees while still providing excellent services. Rob founded the Norwood Park Township Youth Council, which gave young adult students an opportunity to participate in local government.
