Valued by clients for his ability to analyze and respond to complicated commercial litigation, David has built a strong practice representing Fortune 50 companies in state and federal courts. David has served as President of the Federal Bar Association Phoenix Chapter and Lawyer Representative to the Ninth Circuit Judicial Conference, enriching his knowledge and experience to shrewdly navigate the finer points of litigating in the federal courts, particularly involving securities class action defense and IP disputes.

He focuses on a wide range of complex litigation, including securities and intellectual property litigation, class action claims, as well as other large commercial disputes. He has provided regular counsel to large public companies facing lawsuits in Arizona who value his ability to advocate both in oral and written arguments.

David’s practice includes representation of both local and national companies and their officers and directors, naturally adapting his experience across industries, including aerospace, telecommunications, and healthcare. He graduated with honors from Georgetown University Law School and completed mediation training at the Strauss Institute for Dispute Resolution at Pepperdine University School of Law. He currently serves on the Arizona State Bar Board of Governors and the Board of Directors at the Arizona Foundation for Legal Services and Education. He has been recognized in America’s Leading Lawyers for Business by Chambers USA and has been named multiple times as Lawyer of the Year for Phoenix in Best Lawyers® and as a Top 100 Lawyer in Arizona by AZ Business Magazine.
