He graduated with honors from both Northwestern University (with degrees in Chemical Engineering and Environmental Engineering) and Boston University School of Law. He practiced law for several years at Jones Day and Kirkland & Ellis in Chicago in their Intellectual Property Litigation departments. While practicing law full time, he started his own real estate brokerage firm and sold an average of $9M worth of real estate a year on a part-time basis. Since then, Mario’s business has grown significantly while partnering with companies such as Century 21 Sussex & Reilly, Prudential Rubloff Properties and now Berkshire Hathaway HomeServices Chicago.

He has been recognized as being in the top 1% of Chicago Realtors® every year since he started selling real estate in 2002, and his total sales have already amounted to nearly $2 BILLION. Mario has been ranked among the top agents in the nation every year by The Wall Street Journal since 2011. And he has been the Chicago’s top producer in key neighborhoods over the years such as  Lincoln ParkLakeview, Lincoln SquareAndersonville, EdgewaterIrving Park and Old Irving ParkAvondaleUptownRavenswoodRoscoe VillageNorth Center, Wicker Park and Bucktown.
