Within his family law practice, William Kirby values his client relationships above all else. That’s why he does everything in his power to find optimal solutions for their legal matters involving divorce, separation, custody, support, and more. Clients quickly see that William sincerely cares about them and that they can be confident in his advice.

William serves a wide range of clients including celebrities facing high-asset disputes. He is a passionate, appreciative, and motivated person who is dedicated to empowering individuals and families with the right information.

“When my clients come to see me, they are often experiencing a life-defining moment. How they handle the issue can impact the rest of their life and the lives of their family members,” William said. “My approach is to hear what my client’s goals are, so I can provide information and concrete advice about their situation. I know I have been successful when we create a path to the best outcome.”

William refined his strong skill set in litigation and negotiation as an attorney in the U.S. Marine Corps and then as a business litigator representing Fortune 500 companies. He employs his unique background and experience to improve the lives of his clients.

Having been a single father, William’s personal experience with child custody proceedings and mediation allows him to better appreciate the compassion needed to navigate such matters and achieve positive solutions. Above all, William aims to empower his clients to be active participants in shaping the decisions that will move their lives forward toward new beginnings.

William earned his Bachelor of Science in Economics from the U.S. Naval Academy (1998) and was named an Arleigh Burke Academic Scholar.
