Mario was born and raised in Chicago. He came to real estate by way of engineering and law and graduated with honors from both Northwestern University and from Boston University School of Law. He practiced law for almost seven years at both 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, Greco Realty & Brokerage, LLC. GRB, LLC grew to four agents and an assistant before Century 21 Sussex & Reilly acquired it in 2002. He left C21 Sussex & Reilly in 2004 to join Prudential Rubloff Properties creating The MG Group in the process. In April 2014, Prudential Rubloff and Koenig & Strey were purchased and merged into a new brokerage by Warren Buffett’s BERKSHIRE HATHAWAY to form the KoenigRubloff Realty Group. The MG Group is currently ranked #1 statewide and #32 nationally by The Wall Street Journal & REAL TRENDS’ The Thousand Top Real Estate Professionals (2012) and has been in the top 1% of all Chicago Realtors every year since he started selling real estate, amounting to over $1 BILLION worth of real estate sold since 2002. Mario manages Spearhead’s sales as well as residential leases.
