Matrimonial and Family Law matters can be some of the most challenging experiences an individual must go through in life. Unfortunately, the stakes are very high as they often involve matters that will affect the lives of your children for many years to come. It is for this reason that you must consider a lawyer with significant experience in the fields of Matrimonial and Family law. Equally, due to the complexity of these matters, you must consider a full service lawyer that maintains close professional contacts in a vast array of legal disciplines such as coporate, real estate, taxes, etc. such that the attorney is equipped to handle the numerous ancillary issues that come with Matrimonial and Family Law matters. Given the many years that I spent "on Wall Street" allows me to provide strong guidance on financial issues such as asset valuation/distribution, income (both reported and unreported) and financial planning for the future based upon the support package secured in the matter. When choosing a lawyer, It is essential that they have a superior knowledge of the law, an understanding of the many day-to-day demands placed upon a family as they go through this process, coupled with a sensitivity to the fact that resources are better spent on "college funds" for your child than lawyers for litigation. Client satisfaction and effective, effecient representation is my paramount concern. I have spent decades refining my skills in each of these facets and will serve you well. I ask you to simply puruse my client reviews as I believe that they speak for themselves.

Great lawyer and an even better person
Will mentored me when I was starting out as an attorney. I didn’t realize how important his lessons were until years went by and I matured as an professional.

Excellent attorney!!!
No one enjoys this process and you feel a little lost during the whole thing. Luckily we found Mr. Sullivan. I’ve gone to court numerous times for custody and visitation but never felt at ease even with attorneys. Me. Sullivan was very knowledgeable to current laws and his expertise made my experienc...

A father's best friend!
A close friend of mine who is also a Divorce attorney recommended Will to me and I am very glad that he did. Will helped to guide me thru a very trying and challenging time in my life.

Do nit hire
William Sullivan and Kevin Warner of Long Tuminello were my divorce attorneys. They neglected to return phone calls, escalated fees and prolonged a horrible experience. As a litigation paralegal for over 20 years I know a competent lawyer and I did not see that in either of them. I drafted my own co...
