Description of Practice

This Mediator is Certified
We have offered Divorce Mediation services on Staten Island from 1994 until October 30, 2020, when we relocated our practice to Sarasota, Florida. We conduct all Divorce Mediations via Zoom videoconference so you do not have to travel to a Divorce Mediator's office, but can attend from home or work!. 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 a Free initial 30 minute introductory mediation session via Zoom so that you and your spouse will have an opportunity to get to know Mr. Leininger and he can answer all your questions.

What have you got to lose???
