Mark Grossmann

Hall of fameKatten

Mark Grossmann knows how to make deals happen. For more than 20 years, he has guided principals and finance sources alike through critical transactions that have helped them grow, compete and realize value. He is known for a refreshingly direct approach that cuts away extraneous issues and gets to the heart of what the parties need. Mark knows that lawyers are often seen as obstacles who can bury the deal in the legal details. He takes a different approach — one based on market knowledge, sharp analysis and a keen sense of priorities. He'll stand firm to get the "right" terms for every deal, but never lets minor or academic issues bring progress to a halt. By keeping the deal moving toward a timely close, Mark makes sure his clients reap its full benefit, while at the same time protecting their legal interests. A deft quarterback, Mark assembles and balances resources from around the firm to address the diverse issues that arise in every transaction. He weighs competing points of view with client priorities in mind and emerges with strategies that meet both immediate needs and long-term goals. Mark has handled hundreds of transactions in the United States and around the world. Clients often turn to him for insight on "what's market," in a given industry or deal structure. Not only does he know the terms, he knows why they matter and how they will play out from contract negotiations through post-closing operations. Mark has deep experience in industries including finance, technology, manufacturing, consulting, real estate, retail, parking, pharmaceutical, security and health care.
