“Peter Linn is an exceptional mediator and ADR Services, Inc. is fortunate to have him on its panel. 5 out of 5 stars.”

“I was very pleased with Peter’s ready grasp of the facts, his spot-on analysis, and his demeanor in our court-ordered mediation, often the most difficult mediations to conduct. Peter was diligent and seemingly (based on the interaction he described) tried his best to persuade a difficult litigant of the need to settle (unfortunately without success). I would definitely use Peter again and will be happy to refer others to him.”

“I worked with Peter on a few construction defect cases in the past couple of years. He was always very knowledgeable, well-prepared, and easy to work with. Since becoming a mediator, I still find him to be all of these things. He has come well-prepared to mediation with knowledge of the underlying facts of the case, which shows that he had reviewed the mediation briefs in advance. He is friendly during the mediation and has made my clients feel like they were in good hands. He also has been able to come up with unique and out of the box ideas when it comes to case resolution. He is also good at telling you where your strengths and weaknesses are for your case. I find that his mediation style suits him well and is a great service to his clients. I would recommend Peter to other colleagues, and have done so in the past.”

“I have worked with Peter as part the mediation program in Contra Costa County now for several years and every time I get to work with him is a true pleasure. He has a special ability to not only explain the benefits of mediation but also the real-world consequences of trial to not only my clients but also to the other side. He has helped to settle many cases I have had that I thought would never settle, either based on my client or the other side. I routinely hear from not only my clients but opposing parties and their counsel about what a professional and knowledgeable job he does when mediating cases. He will be a tremendous asset to ADR Services, Inc. and I am elated to know that he will still be helping with the mediation program.”
