Born and raised in Chicago, Mario Greco came to real estate by way of engineering and law. 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 KoenigRubloff Realty Group.
Throughout his career, Mario has consistently proven to be a top producer. 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 over $1 BILLION. Mario has been ranked Top 50 in the Nation every year by The Wall Street Journal since 2011. And he has been the city’s top producer in key neighborhoods over the years such as Lincoln Park, Lakeview, Andersonville, Wrigleyville, Irving Park, Avondale, Sheridan Park, Uptown, Ravenswood, Old Irving Park, Roscoe Village, St. Ben’s and North Center.
As the founder and leader of The MG Group at BERKSHIRE HATHAWAY HomeServices KoenigRubloff Realty Group, Mario oversees all pricing strategy, marketing plans and buyer/seller negotiations for all Group clients, and ensures that the Group operates with market-leading expertise and optimum efficiency. He is proud of The MG Group’s widespread recognition for their unique ability to deliver both speed and value to their clients throughout every real estate transaction.
Mario lives in Chicago’s Lincoln Park neighborhood with his rescue dog, Jack.
