Thompson Coburn, a national law firm with six offices across the United States, combined with New York-based Hahn & Hessen, a 44-attorney firm with nearly a century of experience representing financial institutions and other financial market participants in commercial finance, bankruptcy, workouts and complex litigation.

The combination, effective July 1, will create a combined firm with more than 400 attorneys across seven offices in Chicago, Dallas, Los Angeles, New York, St. Louis, Washington D.C. and Southern Illinois.

“Thompson Coburn is all about providing exceptional legal services and value to our clients. Now we can strengthen those offerings with dedicated attorneys in New York, the financial capital of the world,” Roman Wuller, chair of Thompson Coburn, said. “Our combination with one of the premier boutique law firms in their space will provide innumerable benefits to our existing client base, as well as prepare us to serve new financial market participants and business entities across the country.”

Thompson Coburn is an Am Law 150 law firm with more than 50 practice areas. It represents clients of all sizes, including major companies and financial institutions like U.S. Bank, Citibank, Bayer and Kawasaki. Hahn & Hessen represents market participants in a variety of financial matters, including bankruptcies and restructurings, commercial finance and complex litigation.

“This is a tremendous opportunity for us to combine our deep bankruptcy and financial experience in the New York market with Thompson Coburn’s national presence and resources,” Mark Indelicato, managing partner at Hahn & Hessen, said. “When you add in our shared values around professional development, civic and charitable efforts and a diverse and inclusive culture, it’s a perfect fit.”
