  • 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.
