Representative Experience:

  • Michael's trial practice has focused on representing corporations, particularly lenders and developers in various commercial disputes. Most recently and indicative of his reputation, Michael was retained by a lender to represent it on appeal from an adverse judgment and significant punitive damage award in an out-of-state case
  • Michael's expertise in handling appeals arises from his experience serving as a law clerk at the California Supreme Court and the Circuit Court of Appeals for the District of Columbia. He has argued before the California Supreme Court on three occasions, and has appeared numerous times before the Ninth Circuit and the various districts of the California Courts of Appeal
