Description of Practice

This Mediator is Certified
We have offered Divorce Mediation services on Staten Island since 1994. Most of our clients wish to divorce with dignity, and with as little emotional injury to their children. Other clients are attracted to our mediation service because a "cash business" or other unreported income situation is present and they desire total confidentiality while negotiating their divorce.

We offer an initial 30 minute introductory mediation session so that you and your spouse will be able to get a good idea of how divorce mediation will work for you. The fee is only $150 for this introductory 30 minute session - and if you hire our firm within 30 days we will refund the $150 introductory session fee!
