In the 30 years since GKWW was established, the firm has grown from a team of three to a team that spans three offices, in the heart of downtown Chicago, on the shores of Lake Geneva, Wisconsin, and in Naperville, Illinois.

We’ve driven that growth by continuing to do the things that allowed us to grow strong in those early days. We work hard and late. We communicate with clients 24/7. We satisfy client deadlines over our personal schedules. We commit to client goals when approaching problems. We value long-term relationships; we never think shortsightedly. We want our clients to say that we got the job done and to tell others. Throughout our firm’s existence, across the board, they have.

GKWW was established in 1992 and is headed by Thomas Gardiner, James Koch, Lynn Weisberg, and John Wrona. While the name partners’ legal skills overlap, each also has separate areas of special expertise. Tom is a skilled litigator with extensive experience in personal injury, medical malpractice, and wrongful death claims, as well as municipal and business litigation and representation. Jim–who has argued two cases before the U.S. Supreme Court and briefed a third–focuses largely on securities and commodities law, contracts, professional liability, receiverships, and civil and criminal litigation. Lynn teams with Jennifer Airato; together, they have more than three decades of experience in divorce, custody, spousal support and visitation rights matters. John Wrona and the wrongful death and catastrophic injury department have recovered $110,000,000 for clients since 2000. Michelle LaGrotta handles complex municipal litigation and securities.

Today, the GKWW firm boasts a roster of eighteen truly great attorneys with considerable depth and breadth of expertise. We’re highly experienced; we’re efficient; we’re ethical. Most of all, we get things done. We are proud of the results we’ve achieved for our clients, and we invite you to call us for a consultation to see how we might be of service to you.
