Over the course of his legal career, Mr. Sullivan has gained a reputation as a fierce and tireless advocate who aggressively pursues for his clients the most favorable outcomes on their behalf.

He also attended Syracuse University College of Law as a visiting student, and he decided to stay in the area since he felt such a connection to the community.

Shortly after receiving his license to practice, Mr. Sullivan established his law firm in 1996 and has worked since then to provide the highest level of representation possible to those in need throughout his community.
