About Us

At Harrington & Mahoney, each of the partners have more than 45 years experience as private criminal defense lawyers.   Each partner is a Past-President of the New York State Association of Criminal Defense Lawyers. Jim Harrington has served as a Director of the Erie County Bar Association.  Mark Mahoney was elected to the maximum of two consecutive terms as a member of the Board of Directors of the National Association of Criminal Defense Lawyers (NACDL).  Each partner has been sought out as educators to law students, lawyers and judges. 

Mark Mahoney is the only attorney in North America, and perhaps the world, dedicating his practice almost exclusively to the repesentation of those with Autism Spectrum Disorder/Asperger's Syndrome. The top  lawyers across the county who have teamed up wiht tMrk in defending these cases include 8 past presidents of the NACDL. 
Harrington & Mahoney is not a "general practice" law firm.  We are dedicated primarily to the defense of all types of criminal cases and selected appeals and post-conviction matters, but also take matrimonial cases.    When a client comes to us seeking assistance in an area outside our expertise, we are happy to assist in finding the best lawyer outside the firm to help.

Being at one of the busiest border crossings, we handle a large number of matters for Canadian clients, with special attention to potential border-crossing and immigration consequences of criminal proceeding, and the Transfer of Offenders Treaty between the U.S. and Canada. We are privileged to have earned the trust of the most recognized criminal defense lawyers and law firms in Canada, who frequently refer clients to us for help.

Our associate attorneys, Ian Harrington, Connor Dougherty and Thomas Heubusch, have developed a broad expertise in the handling of criminal cases in the firm. Our two legal assistants, Ivonne DeLuca and Denise Dzierzewski, and our receptionist, Debra Logan, are often the primary contacts with the firm, and help us to effectively and efficiently meet the needs of our clients. At any point in time the firm also employs two or more law clerks who take an intense interest in client matters.
