About Florence

Learn Florence’s areas of practice.

A native of Long Island, Florence Fass began her 40 year career in the corporate litigation department of one of New York City’s “top ten” law firms. Ms. Fass soon joined two prominent Nassau County divorce firms, becoming a partner in one of them, and later launched her own firm in 1995. Since its inception, the focus of the firm has always been to provide the highest quality of legal representation in the field. As a result, Ms. Fass is widely respected as a leading matrimonial practitioner, being both a distinguished attorney and a certified divorce mediator. Ms. Fass has lectured for the New York State, Nassau County, and Suffolk County Bar Associations, sharing her knowledge with the judiciary, her colleagues, and the public through personal appearances and radio and TV commentaries.

She prides herself on being in the forefront of the current developments in matrimonial and family law, believing it to be crucial to the effective representation of the firm’s clientele. Given her extensive experience, Ms. Fass is uniquely familiar with the complex financial aspects of the New York State equitable distribution law, while continuing to maintain an awareness and appreciation of the enormous stress which the divorce process places on the client. Ms. Fass believes that she serves her clients best by helping them to focus on the financial realities of their cases, while handling their emotional concerns with the patience and respect they deserve. Her goal in each case is to recognize when a case is ready for resolution, and to work with a client in choosing a resolution that is in their best interest. Outside of the office, Ms. Fass enjoys charity work for under-privileged children, and ballroom dancing.

Divorce is so difficult… it’s like grieving a death… the break of a marriage and a family is a magnanimous loss… I couldn’t have gotten better legal assistance or compassion that at Fass and Greenberg… they were experts in marital law while maintaining empathy and compassion… I recommend them to anyone going through this difficult process.

Expert Legal Champion During a Long and Difficult Divorce
After interviewing other divorce attorneys, I decided to work with Flo on what I knew was going to be an extremely challenging and emotionally draining divorce. Flo was patient, diligent, thorough, compassionate, and always listened to what I needed her to hear. She provided valuable expertise and guidance which I needed in order to make difficult decisions. For three years Flo worked hard for me and in the end obtained the best possible settlement. A tireless advocate for her clients, Flo is among the best in her field, with what it takes to get the job done.

Divorce with Dignity
My exhaustive research on divorce and divorce attorneys led me to Florence Fass. I appreciated her willingness to work with me not just for me. Due to our unique client/attorney relationship my divorce was completed in record time. Thanks to her expertise and expert team I maintained a good relationship with my ex spouse and received a fair settlement. When I found Flo I found gold!

Brilliant, Successfull, Passionate & Well Respected Lawyer
After losing thoudands of dollars to another lawyer who was not even able to get our case heard, my husband & I were on the verge of giving up with very little hope that we would be able to gain custody of my stepchildren. We began to feel helpless as their childhood & future deteriorated right before our eyes. It was a very complicated case, in which the kids were being neglected & dragged through the homeless system. The same system meant to protect our children, did what ever they could to make sure the kids stayed with their mother regardless of her neglect or the fact that the shelters they were staying in were drug infested & dangerous with no place to play outside. As a result we became extemely discouraged with the system since it was evident that however neglectful one might be, children's services will do what ever they can to keep a mother with her children, even when it is not in the child's best interest. Emotionally drained, we were pushed by a good friend who insisted we call Ms. Fass & give it one more try. Ms. Fass was described as being well respected, sucessful & had experience with our specific circumstance (our children, although high-functioning are on the autistism spectrum & are not able to determine what would be in their best interest.) Finally able to obtain a court date, we called Florance the Friday before a holiday weekend. By pure luck, we were able to speak via phone and immediately she graced us with her professionalism, empathy, honesty & guidance. In the first time in over a year and a half, my husband and I had a glimmer of hope. As a result of Florence Fass' knowledge, expertise & guidance, my husband obtained full custody of my stepchildren and they finally have the love, stabilty & safety they so desperately need & deserve. We will be eternally greatfull to Ms. Fass & her team, as if it were not for her passion, competence, care & humanity, our difficult case would not have had the positive outcome it has!
