Michael is recommended by various legal ranking guides, including Legal 500, PLC Which Lawyer, Best Lawyers in America, and Chambers USA, which quotes sources in its 2014 edition who note that Michael is a lawyer who is “an expert in white-collar litigation and antitrust and often represents clients in cases involving a combination of both areas, such as criminal cartel matters.” Earlier editions of Chambers USA note Michael’s “deep and thorough understanding of antitrust law, which is coupled with a patient and proactive work ethic,” and his “reputation as a top-flight trial lawyer for criminal antitrust litigation and cartel work.” For the last nine years, he has been named a Northern California “Super Lawyer” and a leader in the field of White Collar Criminal Defense in a survey conducted by Law & Politics Media Inc. and published in San Francisco magazine.
