I thought he was excellent. While he certainly knows his legal malpractice inside and out, he seems to have the kind of personality that would allow him to effectively mediate any kind of dispute.
- Attorney on a Legal Malpractice Dispute
Very knowledgeable about the matter.
- Attorney on a Legal Malpractice Dispute
Mr. Thompson patiently dealt with my client who while receptive to settlement was not appreciate of the mediation process and ended up leaving. Mr. Thompson continued to mediate and made a mediators proposal that resulted in settlement of the case following the mediation session.
- Attorney on a Professional Malpractice Matter
Challenging case with positions of the parties. Mr. Thompson worked with us, and diplomatically but persuasively "worked us" as well to get aligned with necessary positions. Quality job. Personable in demeanor, not "one gear" through a long day. Moved the parties to the projected position needed and left everyone feeling good about the result.
- Attorney on a Professional Malpractice Legal Case
Peter Thompson did an excellent job on a difficult case on a case with very little likelihood of reaching a resolution. I would definitely use Peter again.
