I love being a lawyer because it suits my personality. I’m good at being a strong advocate while still recognizing the value of achieving the right solution. Advocacy and consensus building are not mutually exclusive.

Ms. Sullivan's litigation practice encompasses the representation of individuals and business entities in commercial, estate, matrimonial, chancery litigation, and alternative dispute resolution. She has significant experience in handling contract and partnership disputes, actions involving closely held companies, oppressed minority shareholder litigation, hiring and termination of senior employees, non-compete issues, and other "business divorce” matters. 

Ms. Sullivan has represented professionals including attorneys, accountants and dentists in various actions, ranging from professional malfeasance to claims of fraud and alleged professional malpractice.  She has appeared before numerous professional boards, including those in the fields of accountancy, dentistry, and mortuary science.

In the areas of estate litigation and matrimonial law, Ms. Sullivan’s practice concentrates primarily on the representation of high net-worth individuals, including the resolution of matters requiring sophisticated business valuations.

Ms. Sullivan is the co-author of two important treatises, New Jersey Business Litigation and Guidebook to Chancery Practice in New Jersey.
