Description of Practice

This Mediator is Certified
We have offered Divorce Mediation services 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. Many other clients have used our mediation services because they have millions of dollars in assets, or own a business or medical practice. Other clients include school teachers, Policemen and Firemen with pensions worth up to two million dollars. All of our Florida Divorce Mediation services are conducted either online using Zoom videoconferece or at our downtown Sarasota location, 677 N. Washington Blvd., Sarasota, which is only 3 blocks north of Fruitville Road and Route 301. Call (941) 727-5555 to schedule mediations in our Sarasota, Florida office. We offer an Free 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.

We offer videoconferencing mediation sessions at no additional cost above our normal hourly rate! This can be of great convenience if one or both spouses must be out of town.

I seek to empower my clients to come to a resolution which they can both embrace as fair and reasonable. Our goal is to encourage Divorce with Dignity with as little harm as possible to the children!
