During his more than 40-year legal career, John Adler was a trial lawyer and legal counselor who represented plaintiffs and defendants, including individual litigants and businesses of all sizes in employment law, class actions/PAGA, contracts, business torts, and personal injury matters. For over 20 years as a first-chair plaintiffs’ attorney, John handled a wide range of civil litigation matters, obtaining and collecting multi-million-dollar judgments at trials in state and federal courts. John is among the very few attorneys in California to have first-chaired a wage-and-hour class action jury trial, having successfully defended the very high-profile, ten-week case in the San Diego Superior Court in 2016. He has orally argued numerous cases before state and federal appellate courts for individual litigants and for corporate entities. John has served for more than three decades as a neutral arbitrator with the American Arbitration Association and began work as a mediator more than 20 years ago. He has extensive experience effectively handling a vast range of legal matters including all types of employment disputes, and business litigation including unfair trade practices, breach of contract, and personal injury.

One attorney who recently mediated with John described him as a “been there” mediator and arbitrator who brings his extensive experience, dedication to fairness, untiring determination to help the parties reach a successful resolution, and integrity. Another attorney commented, “John was truly excellent. He is a perfect choice for my clients because he previously chaired many employment law jury trials and can thus assess the merits and risks of a case. He is able to clearly and persuasively communicate that insight to both me and my clients."

According to John, “I rely on counsel for the parties to provide outstanding advocacy tempered with a recognition of the risks of the litigation process, and the importance of providing resolution, both economically and emotionally. I work tirelessly and with great individual focus to deliver exceptional service to the attorneys and their clients.”

Thank you for your kind words; however, I cannot take any credit. This one belongs to you. I tried for the longest time and it was you who resolved it. Given the lack of evidence I also firmly believe you were able to obtain the best possible settlement for my client. You did a great job and of course, should there be another mediation you would be my first choice.
