About me


I have been defending people accused of crimes in San Mateo, California for more than 35 years.  I understand that being charged with a crime is very stressful. When you hire me to represent you I promise that I will be your side through the entire process.  When you call you will actually reach me or I will call you back right away.  I will use my experience and talent to get you the best possible result in you case.
