Mr. Himmelman mediates virtually every type of dispute involving Federal, State, and local government entities, including (1) numerous False Claims Act and qui tam actions involving tens or hundreds of millions of dollars in claims against defense contractors, subcontractors, and suppliers; private security companies; office, software, and tool suppliers; hospitals, nursing homes, and doctors under Medicare, Medicaid, and the Stark Act; and companies doing business outside the United States; (2) politically sensitive and often intensively media-scrutinized cases involving government departments and agencies, high-level officials, and others; whistleblower and Privacy Act cases, some of which have involved links to former Presidents and the nation’s principal intelligence agencies; (3) employment and housing discrimination; and (4) a host of other government disputes. He is familiar with the unique circumstances faced by all parties in mediations involving government and is adept at working through the multiple substantive and authority issues at play to facilitate settlements. A frequent speaker on a variety of ADR topics, Mr. Himmelman has presented to and trained government agencies, law firms, and bar association participants on how to resolve disputes involving federal, state and local governments.

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.”
