Louis C. Mussari

Of Counsel


Louis C. Mussari is Of Counsel to the Law Offices of Kristen Balbick Degnan. An experienced litigator, he devoted nearly a decade to public service as an Assistant District Attorney in the Erie County District Attorney’s Office before returning to private practice in September 2021.

In addition to playing a key role at the KBD Law Office, Mr. Mussari helms his own law firm, where in addition to Insurance Defense Litigation, he places a strong emphasis on Criminal Defense and Personal Injury law.

There is simply no substitute for the knowledge, quick-wit, and courtroom presence a former prosecutor brings to the table in any court case. Mr. Mussari is a consummate professional in the courtroom and his background as a prosecutor makes him a formidable opponent. Mr. Mussari has successfully litigated jury trials to verdict in the following areas:  Homicide, Rape, Gun Possession, Burglary, Strangulation, and Driving While Intoxicated.

In addition to practicing law, Mr. Mussari is an Adjunct Professor of Criminal Law at the University at Buffalo, where the former prosecutor offers a comprehensive and challenging class in Criminal Law which covers legal research, suppression issues, pre- and post-trial motions and takes a hard look into limitations of the criminal justice system.

Prior to serving Erie County, Mr. Mussari was an associate in the litigation department of Brown & Kelly LLP. In his position with Brown & Kelly, Mr. Mussari handled insurance defense litigation, small claims litigation and no-fault arbitrations.

Mr. Mussari is a lifetime member of the Bar Association of Erie County and serves on the Criminal Law Committee, Solo and Small Law Firm Practice Committee, and the Diversity and Inclusion Committee. In addition, Mr. Mussari is a registered member of New York State Defenders Association.

Following graduation from the State University of New York at Buffalo in 2008 (B.A. Psychology magna cum laude) Mr. Mussari attended Law School at the State University at Buffalo (J.D. 2011). Mr. Mussari was admitted to the State Bar of New York in 2011 and has remained a member in good standing since.
