Shannon Sheehan

Shannon represents property owners in real estate tax assessment proceedings in Cook County and throughout the state of Illinois. She also provides guidance on the latest county and municipal incentives available to industrial and commercial property owners.

Shannon leads real estate tax appeals for a wide range of properties, including office buildings, condominium complexes, all types of residential properties and Class A, B and C industries facilities. She has experience with unoccupied and leased properties, as well as leasehold interests located on property owned by state and local transit authorities. Shannon has represented clients in the RETA appeal process at all levels, including assessors, Boards of Review, circuit courts and the Property Tax Appeal Board.

Whether advising a homeowner, a small business owner, a REIT or a Fortune 500 company, Shannon proactively works with the client to obtain the latest information about a property and develop the best possible appeal strategy for the specific circumstances. Thompson Coburn's RETA group has developed effective relationships with the region's assessing officials, allowing attorneys like Shannon to obtain significant results for clients.

Shannon is one of only two attorneys at the Firm who advise clients in the specific area of Cook County-area incentives for industrial or commercial property owners. She keeps in close contact with county officials to obtain the latest information on incentives, often surprising clients with new opportunities to lower their assessment ratios. This can ultimately result in a substantial decrease in tax liability, allowing businesses to use the saved revenue to create additional jobs, retain at-risk jobs, improve their facilities or use the savings in any other way that's helpful to their operations.
