Haub School of Business at Saint Joseph's University to obtain his master’s degree in finance. He received his Juris Doctor from the Rutgers Law School – Camden in 2013. While there, he was placed on the dean’s list, and he served as the Rutgers Law Journal’s articles editor. 

Mr. Duffy was honored in many ways for his accomplishments and has a great deal of favorable recognition from his peers and clients. The National Academy of Family Law Attorneys listed him in among the Top Ten Ranking Attorneys in 2019. He has written extensively and authored articles for prominent journals.

Staying involved in his community is important to Mr. Duffy.
