Thorsnes Bartolotta McGuire LLP

United States 2025

Overview

Our firm was founded by Michael T. Thorsnes and Vincent J. Bartolotta Jr. when both left the law firm of Higgs, Fletcher & Mack. Less than a year later we added a third partner, John F. "Mickey" McGuire.

Presently there are six partners including Kevin F. Quinn, Karen Frostrom, Brett Schreiber and Ian Fusselman; Mike Thorsnes retired in 2002, but continues to be involved with the firm in an Of Counsel capacity. The firm's focus is on plaintiff's litigation, with an emphasis on catastrophic injuries, wrongful death and construction defects. Our business litigation practice group specializes in eminent domain, inverse condemnation and complex business disputes.

Our firm has earned numerous commendations, among them designation in 1982 by American Lawyer Magazine as one of 20 outstanding new firms in the nation (less than 6 years old) and one of four from California. In 1983, TBM was selected as one of the seven leading firms in San Diego by American Lawyer Magazine.

Since that time, all six partners have favorite success stories, but are proudest of the recognition they have received from their peers in the bar for work in diverse legal fields ranging from construction defects to personal injury to medical malpractice to business litigation. A chronology of the firm includes such awards conferred with astonishing regularity upon TBM partners as "Outstanding Trial Lawyer," "Trial Lawyer of the Year," and "Best Lawyers in America" (for more details about the firm's honors please visit our website at www.tbmlawyers.com ).
