Mr. Himmelman has extensive arbitration experience as the Chair or member of a three-person panel and as a sole arbitrator deciding multi-million dollar claims in a wide variety of practice areas, including: sports, entertainment, and media; medical and healthcare technology supply contracts; hospital system de-merger; intellectual property; law firm partnerships; fraud and fiduciary duty; valuations; employment; franchise; real estate; and probate. He has presented training to law firms, organizations, and bar associations on the subject of arbitration advocacy. He was involved for many years in private practice in representing national and multi-national companies in arbitrations.

In his work as an arbitrator Mr. Himmelman believes that the proceedings must be conducted fairly and efficiently and that decisions must be based on the merits and thus upon a rigorous analysis of the key facts and applicable law.

Counsel Comments

    • “An agreement could not have been reached without Harold’s intervention. He was incredibly well-prepared and a master of shuttle diplomacy. At the appropriate times he was sympathetic, at times forceful. He was always patient. No matter how impenetrable various impasses seemed, he would never give up and always had creative suggestions. He kept both sides, and their lawyers, calm and focused through this highly charged process."

      - Senior Partner, National Law Firm
    • "This was a case of great complexity. It was only because of your creativity, diligence, and faith that settlement was reached. I want to thank you very much for all your efforts. This was in many ways a ‘model mediation in which through your efforts, parties acting in good faith were able to come to an agreement that fully satisfied the interests of all concerned.."

      - Senior Federal Judge
    • “Without your skill and persistence, the litigation in this case likely would have continued for several additional years at great expense in time, financial and human resources to all parties involved. Instead, through the efforts of your good offices, the parties have achieved a mutually satisfactory resolution. You have done a great service not only to the litigants and the court, but to the taxpayers as well.”  

      - Senior Official, Federal Agency
    • “This was probably the most difficult mediation in which I have been involved. I am deeply appreciative of your extraordinary efforts, skill and commitment.”

      - Partner, Top 30 National Law Firm
    • “Your unrelenting efforts to move the parties towards a resolution of this complex and high profile matter resulted in a fair and equitable resolution for all concerned. It is an acknowledgement of your skill and acumen as a mediator that not only was an agreement reached but that the parties are all so pleased with the end result.”

      - General Counsel, Federal Agency
    • “Mr. Himmelman performed his duties as mediator with scrupulous fairness, patience, skill and insight, ultimately enabling the parties to settle this case despite substantial long-standing differences. Mr. Himmelman is one of the most effective mediators we have encountered.”

      - Partner, DC Law Firm
    • “I didn’t think that our chances for success were great, but that was only because I didn’t factor in your expertise. I really don’t think we could have reached a settlement without you.”

      - Partner, Top 100 National Law Firm
    • “I just wanted to express my appreciation for the quality of the mediation service you performed. Disputes, by definition, should never be pleasant to play out. But, the way you handled the proceeding, coupled with your personal comportment and capabilities, made the battle almost tolerable. You are an extremely competent mediator.”
