Our Firm

For over two decades, the lawyers at KCMJ have obtained exceptional results throughout California for a wide range of clients in matters involving disputes regarding business, copyright, real estate, the environment, eminent domain, property loss, and personal injury.  The firm’s clients are both U.S. based and internationally based, but doing business in the U.S.   Many of KCMJ’s clients are referrals from other law firms, who find comfort in sending their clients to a firm of attorneys with substantial trial experience.   KCMJ’s attorneys have successfully taken many cases to trial over the years, including being brought in on the eve of trial to provide trial expertise.  The firm’s ability and willingness to conduct a major trial anywhere in California promotes favorable outcomes for the firm’s clients, and that reputation is one of the primary reasons clients seek out KCMJ.    

KCMJ has a multidisciplinary structure that enables the firm to handle clients' special situations: When a transaction or dispute requires work in more than one area of law, the lawyers frequently collaborate with other attorneys to achieve the best results for the client.  In fact, the firm has a long history and practice of collaborating with other accomplished attorneys and small firms in the execution of sophisticated legal representation for large or complex matters.  KCMJ works as co-counsel with these professionals to add specific expertise or to demonstrate and apply strength through numbers, where necessary for the specific tasks of major litigation matters.  

 While clients seek out the firm because of its outstanding trial experience and reputation for providing the highest quality legal counsel, they are also assured that KCMJ will handle their matter in a cost-effective manner at extremely competitive rates.
