Ken Kasdan

Senior & Managing Partner

Ken Kasdan is considered one of the nation’s leading construction defect authorities who has achieved more than a billion dollars in settlements for his clients in the Western United States. In 2018, he was awarded the Silver Star Award for Best Plaintiff Attorney by West Coast Casualty. He has practiced law for forty years and is the senior partner with Kasdan Turner Thomson Booth, a law LLLC in affiliation with Kasdan  Turner Thomson Booth LLP, established in 1992 where Kasdan is the founding and managing partner.

Kasdan has been at the forefront of construction defect litigation with complex issues involving corrosion of building components, sulfate attack damage to concrete, soil subsidences, water intrusion, and wind-related damage. As a result of extensive litigation and multiple million-dollar verdicts and settlements, the construction industry has modified many of its procedures resulting in better, stronger and more durable concrete used through the Western United States. An important outcome for all.

Well known in the national legal profession and a sought-after speaker on construction defect litigation, Kasdan is a member of the American Bar Association and the State Bars of Hawaii, California, Arizona and New Mexico as well as the Consumer Attorneys of California (CAOC) and construction-related associations such as the American Concrete Institute (ACI) and the International Code Council (ICC).

Kasdan has been licensed to practice in California since 1976. Kasdan is rated AV-Preeminent by Martindale-Hubble, the highest rating achievable for both judicial skill and ethics.
