Services
I am attorney Timothy J. Hennessy, and I founded my law firm to help serve the family law and criminal defense needs of people throughout the greater Buffalo area. I am dedicated to helping people from all walks of life, including area college students, successfully resolve their legal problems.

Whether you have been served with divorce papers or have been pulled over for driving under the influence, you can rely on me to handle all of the legal details while minimizing the stress these issues can cause in your life.I understand that the legal system can feel overwhelming. That is why I always try to keep things simple and understandable while providing responsive representation.
Timothy J. Hennessy, PLLC was founded by Timothy J. Hennessy in 2009. While in law school, Timothy was a member of the Intra-School Moot court team. He was admitted to the New York State Bar in 2009.

After graduating from the Thomas M. Cooley Law School in Lansing, Michigan, Timothy returned home to Buffalo, NY to start his practice in nearby Williamsville, NY with the intention of establishing his firm as the premier criminal and divorce lawyer in the area.I always put my clients first.
A criminal conviction can haunt a person for years, impacting job opportunities, relationships, student loans and many other aspects of life. If your freedom and reputation are on the line, it is critical to get an experienced and determined advocate on your side. I am Buffalo criminal defense attorney Timothy J. Hennessy, PLLC, and my law firm is here to provide the vigorous legal representation you need during this difficult and confusing time.
Drunk driving or driving while intoxicated (DWI) charges can happen to anyone, from college students to middle-aged professionals to retirees. For many people, a DWI charge is the first time they have any contact with the criminal justice system. If you have been arrested for suspicion of drunk driving, it can feel overwhelming and you may not know where to turn next.
DWI laws in New York State are a jumble of statutes, updates and case law decisions amassed over the years. Only a lawyer qualified by years of experience pleading drunk driving cases can speak with any authority about the charges made against you. Because of the many colleges in the Buffalo area, and the frequency of student arrests for DWI, underage DWI and DWAI, we have compiled answers to some of the most common questions.

We selected Tim Hennessy while living outside of NY state but despite the distance and time change Tim was eager to work with us. He has always been available when we needed him and he has continued to provide honest, level-headed advice before, during and after our time in court. We never felt that we were over billed for the services provided and will continue to work with him as the need arises. Thank you, Tim!

Tim is an outstanding family court attorney for custody cases and child support cases and very reasonalble with his rates and hours to complete a case. He knows the law extremly well and will look into the law to see if there are any other options instead of going down the same old road. I ahve been divorced for 15 years and my ex-husband has had me in court almost every year for 15 years. Tim is one of the best attorneys I have used. He also is truly a person of good character, family oriented and honest. All around a terrific person. You won't be unhappy you used him.
