When commercial disputes heat up, Ann works to cool things down so her clients can get back to taking care of business.

An award-winning litigator, Ann calls upon her years of experience to quickly assess the situation and offer workable solutions. Ann understands that litigation is expensive and distracting for clients—whether it involves contract disputes, dealership termination, lease quarrels, contested noncompete agreements or intellectual property issues. She looks to resolve disputes in a practical way to keep the wheels of commerce turning smoothly for her technology, manufacturing and transportation clients.

More than a litigator, Ann also advises general counsel, company presidents and other organizational leaders on a variety of business and legal issues.

Ann serves on the firm’s Executive Board.
