Car Accident Attorney

Dillon Mesi

Attorney Dillon Mesi was born and raised in Orchard Park, NY.  He earned his undergraduate degree in 2018 from Kent State University, in Kent, Ohio. He then graduated from The University of Dayton School of Law in 2022. During his time at Dayton, he was employed with an Ohio law firm criminal defense, criminal prosecution, family law, and estate law. Dillion says, “Spending time working for clients who require public defense helped me understand how often these individuals are disadvantaged in so many social aspects of their lives. Being able to show them, that they are entitled to the same constitutional right to an attorney as anybody else, can help instill hope, and was very rewarding. The internship provided me with invaluable legal experience, coupled with an empathetic approach to working with my clients.


Dillon’s decision to become a lawyer was rooted in his desire to help people. “There was always a certain challenge that comes with the territory of going to law school and eventually becoming a successful attorney that has always appealed to me. But most importantly, I decided to become a lawyer because of the unique situation it puts me in that allows me to help the people who truly need it. I am practicing law to help provide hope to individuals who find themselves in disadvantaged situations, usually due to no fault of their own.”


Dillon has been a part of the William Mattar team since 2019, as a summer law clerk during his first year of Law School at the University of Dayton. “I applied for the clerk position, knowing it would be a great opportunity to develop my knowledge of the law and experience in the field. Once I joined the team, I became exposed to the work of incredible attorneys and knew I wanted to join their ranks.”

Dillion was raised with a strong, never quit, work ethic. He believes that this mentality has helped guide him to where he is today. Dillion is honored to help William Mattar clients.
