Matthew J. Trostler is a partner in the Los Angeles office of Borton Petrini, LLP. He received his undergraduate degree from the University of Southern California in 1988 and earned his Juris Doctorate from California Western School of Law in 1991, where he was a contributing editor for the law school newspaper. He continues to publish articles on a variety of legal-related topics to this day.


For the past 20-plus years, Matthew has litigated both general and complex civil litigation cases including personal injury and catastrophic injury defense, product and premises defense, contract and business defense, toxic tort and employment defense. One of his strengths, however, has been the defense of suspicious and unmeritorious claims. His wide-ranging experience in the field of insurance has provided additional insight to insurance carriers through seminars defining and discussing insurer regulations in California.


Matthew’s clients also come to him for the defense of homeowner’s associations and property management companies. In a case of first impression in California, he successfully argued to the Court of Appeals the proper procedure to be employed by an association governing body when amending governing documents.


He has significant experience in arbitrations, mediations and jury trials. His verdicts have been published statewide and nationally. He has also been published at the appellate level, having both prosecuted and defended appeals in a variety of contexts.  Matthew has taught classes focusing on the structure of the civil litigation system and the jury trial process. His aggressive applicational style is tempered by his sense of fairness and compassion.
