  • Steven Hideki Nakano

    I endorse this lawyer. I have known Dan Mayfield for many years. We have handled many co-defendant cases together, including a case where we represented Stanford Students who advocated divestiture of Stanford's investment portfolio in companies doing business with South Africa during Apartied. Dan is a tenacious lawyer, principled advocate and teacher. All of these wonderful qualities are what make Dan Mayfield a great and successful lawyer.

  • Maureen Furlong Baldwin

    I endorse this lawyer. Dan is one of a kind. He believes truly in justice for all! And practices what he preaches. He has been involved in a number of high profile cases, defending members of ethnic groups that are targeted by the authorities, as well as bolstering the right of peaceable assembly. He also has a high profile criminal practice in San Jose, and takes the time each year to assist new lawyers with the new laws passed every January. Anyone who is lucky enough to be represented by him has a skillful and zealous advocate
