About David Herbert

Few lawyers in California have careers that begin as far back as the mid-1960s. David Herbert Katz was admitted to the bar in 1964 and remains an active member of the California bar in 2026. That span has given him a perspective on the profession that only time can produce. He has been part of the legal landscape through decades of change.

Katz laid the groundwork for his career in two well-regarded institutions. He completed his undergraduate studies at the University of Miami. He went on to earn his law degree from the University of Michigan Law School. Those formative years set him on the path to practicing law in California, where he built a long-running legal practice after admission to the bar.

Over more than six decades, Katz has maintained an active legal presence in California. He has practiced continuously since his admission in 1964. That continuity means he has worked under many iterations of state procedural rules and statutory frameworks. He has seen shifts in courtroom technology, changes in discovery practice, and evolving standards in appellate procedure. Such a lengthy career also indicates long-term engagement with the court system and the bar community.

Colleagues and contemporaries often note the value of lawyers who bring institutional memory to current matters. Katz’s years in practice allow him to draw on a deep familiarity with California courts and legal processes. He has represented clients and appeared before state tribunals, applying decades of courtroom experience to present-day cases. His approach to cases reflects the accumulated judgment of a practitioner who has worked through the practical realities of litigation and client representation over many years.

Outside the courtroom, Katz’s education and prolonged tenure in practice inform how he advises clients and manages files. He has adapted to changes in legal practice while continuing to operate under an active license. In recent years his work has remained based in California. He currently maintains an active law practice in California, concentrating on matters arising under state law.
