Peter J. Linn brings more than 25 years of trial-tested litigation experience to his current work as a full-time neutral, where he is known for his rigorous preparation, grounded insights, and results-oriented approach. Since transitioning to alternative dispute resolution, Mr. Linn has mediated more than 500 matters and earned consistent praise for his ability to navigate complex disputes with patience, clarity, and creativity.
Prior to joining ADR Services, Inc., Mr. Linn built a highly regarded litigation practice representing clients across the commercial spectrum—from individuals and small businesses to large institutional entities. His casework spanned real estate, construction, employment, business torts, personal injury, and professional liability. A seasoned trial lawyer, he has successfully taken numerous high-stakes cases to verdict and handled appeals in both state and federal court. Over time, he developed a reputation as the attorney clients called when the facts were messy, the law unclear, or the personalities difficult.
That skillset now defines his work as a mediator and arbitrator. Mr. Linn is often described by counsel as a calm, pragmatic presence—someone who “does his homework,” listens intently, and creates an environment where clients feel heard and attorneys feel respected. He is particularly valued for his ability to “see the big picture dynamics” of a case—beyond just the legal arguments—and tailor solutions accordingly.
As a mediator, Mr. Linn is deeply evaluative and brings the full weight of his trial experience to bear. He engages in advance with counsel to understand the legal, procedural, and emotional landscape of each case, then uses that information to prepare meaningful conversations with parties. Attorneys consistently note his credibility, strategic thinking, and effectiveness with both sides of the bar. Whether helping parties test legal theories, reframe risk, or navigate difficult personalities, he is committed to resolving disputes efficiently—and, just as importantly, with integrity.
Mr. Linn is unapologetically results-driven. He believes that while the process matters, it must ultimately lead somewhere. Whether the dispute is straightforward or deeply entrenched, his goal is to get parties to resolution—or as close to it as possible. He is known for his willingness to keep working post-session, his skill in reframing difficult conversations, and his ability to build trust with clients, attorneys, and insurance representatives alike.
He is especially adept at untangling complex, high-conflict matters—disputes often mired in a web of disputed facts, procedural hurdles, and heightened emotion. With a keen eye for structure and strategy, he approaches each case by stepping back, assessing the full picture, and reverse-engineering a path toward resolution.

Mr. Linn is a co-creator and presenter of a Continuing Legal Education program entitled “Mediation Boot Camp” offered to law firms throughout California. The program is designed to teach lawyers new to the practice of law about effective mediation strategies.
“Peter was nimble, creative, effective, great! Got the job done and I will be glad to work with him again. ”
“Peter did a great job. The case itself is a bit unusual for a real estate case and Peter was able to think out of the box to get us on the road to a resolution. He has been professional and thoughtful in all of my communications with him as well. Peter will certainly be on my list of mediators to use in the future.”
“Mr. Linn has been very energetic, helpful and effective in steering the parties toward a resolution. He was knowledgeable and quick to get up to speed on the issues of our case.”
“Peter Linn was very professional and effective throughout the mediation, and given his knowledge and experience–he provided credible insight into the issues of the case.”
“Mr. Linn was excellent in a very difficult and complex matter involving solar array power generation. He “tamed the beasts” My clients were very happy with his demeanor, creative approach and tenacity. He’s two for two for me and is on my firm’s A-list.”
“We really appreciate Mr. Linn’s willingness, and perseverance, not to let this just go unresolved, ultimately leading to resolution.”
“Peter Linn was an excellent mediator and I look forward to using him again on other cases.”
“Peter Linn has served as mediator in several of my real estate and business cases. Peter is an excellent mediator, well prepared and patient. He helped me settle several complicated cases that I did not think would settle.”
“Mr. Linn did a great job. He stuck it out with the parties for over nine hours, managing to pull a settlement out of the fire at the last minute. He was friendly (maybe friendlier in demeanor than most mediators I’ve encountered), but he was still able to straight talk to the parties to get them to see downside and risk. The bottom line is whether he was effective, and he certainly was. He will be on my list of mediators to use when the dispute stems from conflicting personalities in addition to strategy get-forward business disagreements.”
“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.”
