Don Sinkov


Divorce Mediator



Don Sinkov is a Divorce and Separation Mediator in private practice in Westchester and Putnam Counties. He mediates divorce, post divorce, custody visitation issues and move-out agreements. Don has mediated over 2000 cases and believes his approach to mediation gives clients the best possible service.

As an expert mediator, Don is frequently called in by attorneys to help mediate complex divorce/custody issues, high asset individuals and non-traditional couples. Many attorneys and couples use Don’s services before, after and during litigated cases to help reduce costs.

Back in 2002, most of my friends were getting divorced, and I heard stories about the outrageous costs, the lawyers battling, the years of litigation, and the damage it caused to everyone in the family as they went through their divorces. I thought I could use my skills as a mediator and arbitrator to help couples get separated and/or divorced without the fighting and high costs..

Don enrolled at New York State of Industrial Labor Relations at Cornell University. He spent three years studying labor law where he earned a BA Degree in Labor Studies.

Studying labor law increased his effectiveness as a shop steward and later Don was elected Division Chairman. He further honed his skills serving as Arbitrator Chairperson for the securities industry, chairing and arbitrating cases for NASD, the Futures Exchange and the New York Stock Exchange that included firms such as Bear Stearns, Alliance Capital, Sanford Bernstein, Merrill Lynch, and Goldman Sachs.

In addition to the securities industry, Don served as the Lemon Law arbitrator for the State of New York mediating disputes between car dealers and customers. He also volunteered for community mediation for a Community Dispute Resolution Center (CDRC) arbitrating hundreds of cases of landlord tenant disputes, neighbor to neighbor disputes, etc.

Don continued to study in different venues of arbitration and mediation and eventually chose to specialize in divorce mediation.

It’s not about anyone winning like litigation; It’s about the couple walking away with a good agreement they’ve constructed for themselves in light of the information I’ve given them. Their decisions should be rooted in sound law and not based on emotions. My hope is that they will look at this agreement five years from now when they are no longer emotionally involved in it and appreciate the fact that we didn’t allow the agreement to be based on the emotions of the moment.

I have people who call me years later and refer cases to me; their neighbors, their family members or they just put the case in my hands and say “we’ll follow your recommendations. We know we can trust you”. That’s as good as it gets as far as I’m concerned.

Areas of Expertise

Don looks at things analytically like an attorney rather than a therapist. He believes couples who come to him just want to get through the process as quickly and inexpensively as possible and not get taken advantage of. Don wants the time they spend with him to flow and to do that he follows an outline he has developed that address all the issues:

  • The Children – child support, custody, visitation
  • Assets and Debt – Equitable distribution of assets and debts of the marriage
  • Alimony/Maintenance – Whether or not the factors are present to include alimony and how it will be paid.
