In his practice, Chris has been a first chair trial lawyer with more than 30 years of experience handling high stakes, precedent-setting cases, particularly in the products liability arena. His most recent products liability engagements included serving as trial counsel for a large talc company, including trying to conclusion one of the very first mesothelioma cases against it, and leading a cross-office international and national team defending multiple Chinese companies in a historic MDL. At times, a client asked Chris to lead five or more trial teams in products cases in a single year.

He has extensive experience in complex and commercial litigation, ranging from insurance recovery disputes to trade secrets issues, and has significant experience in assisting foreign aerospace companies with international arbitration disputes with first-tier aircraft manufacturers.
Earlier in his career, Chris represented large public companies in mergers, acquisitions, strategic investments and private financings; private companies in initial public offerings; and emerging growth companies in general corporate matters. Chris' transactional experience also offers clients a unique perspective on risk mitigation strategies to avoid costly litigation in the future.
