Counsel Comments

    • "As I am located in Los Angeles, I asked several of my colleagues in New York for recommendations for a mediator there, and Judge Holtz’ name was provided by more than one, and with highest recommendation. She lived up to the billing. Very easy to work with, very engaged and engaging, and a very effective approach and style."
      – Prominent, top ranked trademark, copyright and trade secret Attorney, California
    • "Judge Holtz went above and beyond the call of duty to get our case settled. Despite that fact that the mediation session had ended without the parties being able to resolve their differences amicably, Judge Holtz did not give up. On her own, she reached out to counsel believing that the matter could still be settled, and used her skill and experience to get it resolved. The parties saved a considerable amount of money from what they would have had to spend if they had had to proceed to arbitration. Truly, the case would not have settled without her and she did an outstanding job. I will definitely use her as a mediator again."
    • "It has been a long day, but just wanted to thank you on behalf of my client. As you could see there was A LOT of emotion wrapped up in this and she really needed this closure. You were one of the best mediators I have worked with and I will 100% see you again. Be well and thank you!"
      – Litigation Partner
    • "Judge Holtz was excellent. Good knowledge of the facts and law, and really good personality."
      – Trial Attorney
    • "Judge Holtz was by far the best mediator I have used in my career."
      – Boston Attorney
