The Story
More Than Just
an Agent
Kealan O’Neil isn’t your typical real estate broker. As the founder of O’Neil Property Group, he’s spent over 22 years building something different — a brokerage where local knowledge, honest communication, and real relationships come before transactions.
Born and raised in the western suburbs, Kealan knows Kendall County the way only a lifelong resident can. Every neighborhood, school district, backroad, and hidden gem. That knowledge — paired with modern marketing, technology, and a team that genuinely cares — is what’s earned OPG the trust of over 500 families and counting.
When he’s not helping clients buy and sell homes, you’ll probably find him exploring local restaurants, spending time with family, or talking about his next big idea for OPG.
