Mario Greco is a distinguished leader in the Chicago real estate market. He is known for his steadfast commitment to professionalism, efficiency, and results. Since launching his career in 2002, he has made the MG Group one of the industry’s most respected firms.
He saw early on the need for agents who were not only knowledgeable but also highly responsive and organized. He founded MG Group to provide a seamless, results-driven client experience.
Mario evolved from being a solo agent handling every transaction aspect to the visionary CEO of his powerhouse team. Although he focuses mainly on the business’s strategic vision, he remains involved in its daily operations.
He works with selected buyers and sellers to stay connected to the work that first inspired him. His leadership ensures that MG Group continues to uphold its reputation for excellence in service and execution.
Mario’s approach is direct. He believes in telling clients what they need to hear, not just what they want. He prioritizes honesty over concession, whether on home pricing or advising sellers on presenting their property well. This candid approach has earned him lifelong clients who trust his advice and frequently refer friends and family.
Many industry accolades have validated his approach. These honors extend beyond consistent top rankings in the Chicago real estate market. The firm receives mentions from prestigious publications such as The Wall Street Journal and Crain’s Chicago Business.
Beyond his real estate dealings, Mario has also become a trusted advisor to his clients after the sale. They ask for guidance when they need reliable contractors, attorneys, or financial professionals. His legal background and understanding of negotiations make him a formidable advocate. With his skills, experience, and support from the team, he ensures his clients achieve the best possible outcomes in every deal.

Mario’s vision for the MG Group is clear. He wants to continue strengthening its reputation for integrity, efficiency, and results while building an infrastructure that ensures long-term sustainability. He is committed to cultivating top talent so that his team upholds the high standards that define the MG Group’s success.

His goal is for the company to thrive independently, even as he steps back when the time is right. He wants to rest knowing that the business will continue operating at the highest level.
Mario has set a new standard for real estate professionalism throughout his career. He has a reputation for proficiency, transparency, and client service. Clients who choose the MG Group know they are working with a team that doesn’t just navigate the market. The team anticipates and outmaneuvers challenges to deliver exceptional results.
Under Mario’s leadership, the MG Group is in a great place. It has a strong reputation and built a legacy of success. However, Mario is always looking to grow, improve, and innovate.
