Our Services

What We Offer

With our collective expertise we offer a full range of alternative dispute services


Mediation Services

Conflict exists; disputes may lead to legal action.  Mediation is a dispute resolution process that allows parties to engage in a joint search for mutual gain to end the conflict using the services of a mutually acceptable third party.

Case Consulting

Want a second opinion? Will mock argument/mock trial opportunities hone your court appearance? Concurrence ADR can help. We collectively have over 90 years’ experience handling complex litigation matters

Appellate Consulting

Appeals are unlike other forms of litigation as the issues and arguments are limited by the record made in the trial court. Effective appellate advocacy begins at the trial court level and continues through issue selection, briefing, and oral argument preparation.

Decision Makers: Arbitration and Referee Services

Parties sometimes prefer to resolve their dispute outside the eyes of the public.  Concurrence ADR has the experience and expertise to provide arbitration and referee services so as to resolve disputes in a binding, prompt and private manner.
