Counsel Comments

    • "Excellent legal knowledge and first rate Mediation skills. I would recommend him highly. I would rank Mr. Isserles among the best Mediators I have encountered.”
    • "Mr. Isserles is an intelligent, persuasive, thoughtful, empathic and patient mediator. He is a pleasant person to spend the day with and is careful to always keep the focus on the clients. These qualities enable the parties to reach a handshake without even realizing their arms had been twisted.”
    • “Marc has that rare and perfect combination of mediator skills - patience, persistence, personable, and razor-sharp smarts. He quickly masters legal issues and gets to the heart of a dispute and what drives each side. He masterfully helped resolve my multi-party action involving a number of strong personalities.”
    • “Mr. Isserles was an impressively prepared, skilled, and patient neutral who worked tirelessly to get the parties together in a hotly contested federal case. I would recommend him without hesitation.”
    • “After the parties experienced an unsuccessful and very contentious mediation with another mediator, Mr. Isserles stepped in and managed to professionally and expeditiously resolve the parties' complex partnership dispute in less than a day.”
    • “Marc Isserles was able to settle a multifaceted commercial case involving multiple parties, in which no one going into the mediation believed would ever settle. The case, which had already been through a full hearing before the California Labor Board, in connection with a breach of an Artist’s Manager contract, was extremely contentious. Marc quickly assessed the situation, identified the issues and managed to deal with some extremely difficult clients on both sides of the table. He had thorough knowledge of the law, knew the history of the case and effectively used this information to work with both sides. Marc persevered even when he was told by both sides there would be no settlement. Before the evening ended, a deal memo was signed. I recommend Marc without reservation.”
    • “Marc Isserles served as a mediator in a complex commercial dispute involving numerous disputed legal and factual issues. Throughout the process, Marc demonstrated great skill, patience and understanding in dealing with the parties and their respective claims. He is smart, open-minded and demonstrated a unique ability to come up with possible creative solutions for settlement throughout the mediation process - all the while maintaining the respect of the litigants and counsel. I would certainly recommend Marc to be a mediator in any commercial dispute and feel confident that his involvement will be favorably received by all participants.”
    • “Mr. Isserles served as mediator in a commercial contract dispute. He quickly became conversant with the factual and legal issues involved in the case and, just as important, identified the practical impediments to settlement and brainstormed with the parties how they could best be overcome. Before the day of mediation ended, we had reached a complete settlement that might not have been attainable with a less skilled mediation professional.”
    • “Marc has the qualities found in only the very best mediators - intelligence, attentiveness, creativity, and persistence. I very much look forward to working with Marc again.”
    • “Marc helped us resolve a business dispute in which personal feelings ran high. He showed intelligence and attention to detail, and dealt with the parties with energy and humor. We would recommend him highly.”
    • “Marc is a highly effective mediator who is smart, well-prepared and engaging. He was instrumental in resolving a complex commercial matter at mediation. I would recommend him without qualification.”
    • "Marc did a great job in a relatively small but emotionally-charged employment/bonus case. I thought he...showed excellent judgment and excellent people skills in bringing the parties to the right compromise figure. Importantly, he showed creativity and doggedness in working through a very tricky procedural issue after the parties had agreed on the settlement amount. In a good and respectful way, he wouldn’t let us go home and give up, and we eventually found a way through the issue.”
    • "Marc is a highly effective, intelligent mediator with a remarkable work ethic. In a highly contentious employment case, he was personable and patient, well-prepared, and completely impartial. Marc was instrumental in bringing about a good result for all parties. I would recommend him without reservation.”
