With more than 40 years of jury trial, products liability, and insurance litigation experience, David Frohn focuses his practice on the defense of domestic and international manufacturers of consumer and industrial products. David has extensive experience defending claims involving recreational vehicles and boats; personal watercraft; medical equipment, implants and devices; sporting arms and ammunition; industrial tools and machinery; refinery and chemical plant process vessels; commercial transportation vehicles; and electromechanical fire cause and origin.

Admitted to practice in Louisiana and Texas, David earned his JD from Loyola University of the South School of Law, New Orleans. He holds a Bachelor of Aerospace Engineering from the Daniel Guggenheim School of Aeronautics and Astronautics at the Georgia Institute of Technology (Georgia Tech). He is a Louisiana licensed Professional Mechanical Engineer with work experience as a Quality Control Engineer for the Boeing Company and as a lawyer with Exxon Company, U.S.A. He combines his legal and scientific skills to assure the best possible outcomes for his clients.

For more than 25 years, David has been Board Certified in Civil Trial Law and in Civil Pretrial Practice Law by the National Board of Trial Advocacy. His Diplomate rank with the American Board of Trial Advocates (ABOTA) certifies he has tried more than 100 civil jury trials to verdict as lead trial counsel. An AV rated lawyer by Martindale Hubbell, since 1987, he has also been named both a Louisiana “Super Lawyer” in the field of products liability defense and a “Top Attorney in Louisiana” for personal injury defense/products for the past 15 years. He served as lead counsel on one of the first US Circuit Court decisions in the United States to affirmatively hold that criminal handgun violence is not a liability against gun manufacturers.

Upon Louisiana’s reform of its products liability law, he presented a continuing education seminar for fellow attorneys through the Louisiana State University School of Law, Office of Continuing Education to explain how Louisiana’s tort reform law defines the rights and liabilities associated with injuries and damages arising from the use of manufactured products. He also presented a CLE seminar through LSU’s Center of Continuing Professional Development on the intricacies and exclusions of the Standard Commercial General Liability Insurance Policy. He co-authored and edits Louisiana Civil Trial Procedure, West Group (Lawyers' Cooperative/Thomas Reuters), and served as contributing author for “Exclusions of Improper Expert Testimony,” Product Liability Advisory Council, Inc.

David’s volunteer service to the Bar included serving as a member of the Louisiana Attorney Disciplinary Board for 11 years, culminating in his service as board chair of this adjudicative body charged by the Supreme Court with responsibility for lawyer discipline statewide. Previously a member of the Louisiana Supreme Court Bar Admissions Committee, he wrote the Louisiana Civil Procedure exam for the Louisiana Bar Examination.
