Trust Our Experience

James L. O'Keefe started the firm with a commitment to providing clients with exceptional thinking, strategies and results to resolve their property tax matters. Today, decades later, that timeless approach still guides our real estate tax practice.

O'Keefe Lyons & Hynes, LLC has carefully selected attorneys who have a strong dedication and understanding of property tax law and a demonstrated ability to delve deeply into complex issues. Our lawyers have worked in the public sector -- from the Cook County Assessor's Office to the Board of Review for Cook County -- and understand the complexities of property tax appeals and litigation, property tax planning, and related matters. One senior member of our firm argued an appeal that upheld a significant revision of the Illinois Property Tax Code for the State's Attorney's office and leads a nationally-recognized property tax litigation team.

While there are many firms that can file property tax appeals, the O'Keefe firm brings an unparalleled level of expertise and a passion for helping clients maneuver through challenging property tax matters.

The firm's clients are prolific commercial real estate developers and prominent property management firms, global industrial concerns, marquee hotels, national retailers, shopping center developers and Fortune 500 corporations. These clients include Chicago area hospitals, small businesses, apartment complexes, condominium associations, and not-for-profit and religious organizations.

Clients rely on the firm for its thorough knowledge of the law and the commercial real estate industry, creative and strategic thinking, integrity and hard work. Whether the matter involves a single Cook County tax appeal, a unique City of Chicago office development, or a complex, multi-municipality portfolio of properties, the O'Keefe law firm can quickly assess the situation and provide expert guidance.
