About Us

The Firm was started in 2002 as medical providers and injured victims sought out the expertise and commitment of Sean T. Hagan.

Sean is a graduate of Ursinus College with a BA in Politics and Certification in Social Studies Secondary Education. While teaching in Philadelphia at the J.R. Masterman School in Center City, he attended Widener University, School of Law in Wilmington, DE. Sean graduated Cum Laude from law school in 1998 with Letters of Achievement in Insurance Law and DE Civil Practice. He immediately passed the NJ and PA bar examinations and was sworn into both states although he currently is only active in New Jersey.

Sean immediately began practicing law throughout New Jersey handling Personal Injury Protection arbitrations, automobile accidents, slip and fall injuries, worker's compensation cases, municipal court matters, family law and real estate transactions with the primary focus on Personal Injury. In the beginning of 2002, he spent six months as a defense attorney representing major insurance carriers and their insureds while taking and passing the NY bar exam.

At the request of several medical providers, Sean hung his own shingle and mastered the art of fully representing clients, recovering the greatest amounts possible and keeping the clients fully informed along the way in writing and telephone. He works closely with some of the largest personal injury law firms in the state to provide the best services for his clients. He has access to offices throughout the state and provides referrals to the most appropriate attorneys when needed.

In 2006, Fran O'Connor joined the Firm as a paralegal with experience and expertise in Personal Injury Protection recovery and arbitrations. For the past 20+ years she has served as an insurance supervisor at a large medical provider office, as a litigation supervisor at a provider management vendor for various health disciplines, and as a paralegal. Let the Law Offices of Sean T. Hagan LLC handle your matters with superior service and personal touch and dedication.
