Who We Are

Who we are

Owned and operated by seasoned Chicago real estate professionals, we have an intimate understanding of Chicago’s neighborhoods, market trends, and property conditions. Founded in 2010, owner John McGeown brings his Navy background into the leadership and operations of the company, which has grown into more than 1,000 units, mainly through referrals. We’re constantly creating new roles and promoting from within, adding more in-house staff to eliminate third party vendors, which provides more operational and cost control. We have legal counsel, janitorial services, on-call maintenance technicians and a dedicated leasing team – all in house.


John McGeown


John McGeown entered the industry in 2004 as a listing agent for Chicago Apartment Finders. He paid his dues by cold-calling thousands of landlords each week, listing over 2,500 rental properties in three years, before working his way up to account manager, and then listing and marketing director.

Over 1,500 transactions later, John wanted to learn more about the operational and sales side of real estate and became an agent with Jameson|Sotheby’s International Realty in 2008. In order to meet the increasing demand for property management services from his clients, John started High Fidelity Property Management in 2010. Since then, his knowledge of and enthusiasm for Chicago real estate have only grown. John has helped hundreds of clients buy, sell, rent, lease and manage properties all over the city.

Born and raised on Chicago’s north side, John has also been a resident of California and Scotland. He served in South America and the Middle East (Operation Iraqi Freedom) as an Operations Specialist with the United States Navy. He credits much of his success to the support of his family and to his life philosophy: Be a leader. Never stop learning, and try your best to think outside of the box.
