Will is a Senior Member of The Cavanagh Law Firm. He has been solving challenging family law problems for people for 20 years. Whether it be complex, large-asset divorces, hotly contested custody battles or disputed adoptions, he has the experience, determination and drive it takes to get the job done. Will’s aggressive yet no-nonsense, professional courtroom advocacy has earned him the respect of his clients, opposing counsel and judges alike. He is an experienced litigator, having represented people and companies in countless bench trials and numerous jury trials over the course of his career, a rare attribute of a family law attorney.  

While Will thrives on battling for his clients in the courtroom, just the same, he gets tremendous satisfaction from helping clients negotiate settlements of their cases and avoid the stress of going to court when that’s what they need. His level-headed, compassionate approach to case resolution inspires confidence and comfort in the most difficult times.  

Will earned his juris doctor degree with honors from Indiana University School of Law. He earned his bachelor's degree with highest honors in business, with an emphasis in economics, finance, and risk management. That education, and his entrepreneurial spirit, serve as a foundation for his practical problem-solving approach to the business and financial aspects of his clients’ cases.

Will takes great pride in helping people in the most trying times. He served his community as a volunteer firefighter and emergency medical responder from 1996 to 2023. As a fire department battalion chief for more than 14 years, he was responsible for commanding emergency incidents, ensuring the safety of responding crews, and mitigating dangers at fire and accident scenes.  

When he’s not busy helping people resolve their divorce, custody, and adoption cases, he enjoys home improvement projects, cycling and off-roading.
