Counsel Comments

    • "You did a terrific job bringing peace to our valley."

      - Litigation Partner
    • “[Judge Chapman is] an EXCELLENT mediator…. [She works] extremely hard, [is] wise, tough when it's called for, super smart and knowledgeable and [has] some fun in [her] too! [She did a] great job in accomplishing what we thought would never happen this week!”

      – Principal at Business Litigation Firm
    • "[Judge Chapman] really grabbed the parties' attention, and we walked out with a term sheet that day, which was unexpected and I think quite an achievement for the mediator.... She knows how to identify those aspects of your case that you need to evaluate most closely, that offer you the most unpredictability. And that's what makes people move."

      – Litigation Partner
    • "I think [Judge Chapman] must have worked some magic behind the scenes so to speak. I can't fully explain how she did it; I just know she got it done.... I don't believe in luck or coincidence, but I do believe in experience."

      – Intellectual Property Litigation Partner
    • "It wasn't your typical mediation where you're fighting over money all day; it was ... more complex. [Judge Chapman] was tireless and just worked really hard to get us to a point where we could both walk away."

      – Litigation Associate
    • "[Judge Chapman] tends to have a little more weight than your typical mediator. She adds value. ... She just kind of gives you the information she needs to give you so you can make a good decision."

      – Principal in Business Law Firm
    • [Judge Chapman] resolved both of [my cases] very shortly after the mediation. The follow-up is, at least in my mind, one of her strengths."

      – Principal in Small Firm
    • “We appreciate [Judge Chapman’s] diligence, thoughtful opinions, well-reasoned decisions and tireless work. We would highly recommend  [her] as an arbitrator in future matters.”
      – Litigation Partner
