"E Pluribus Unum"
Compassionate, Powerful Legal Representation

San Jose Criminal Defense Attorney

The Law Office of Gregory M. Alonzo has provided high-quality legal services for both felonies and misdemeanors to clients for more than 35 years. As a San Jose criminal defense attorney, I am well-respected by judges and prosecutors alike. My reputation as a strong negotiator and aggressive advocate for the rights of the accused is well-known in the Santa Clara County court system.

I understand the fear and uncertainty one feels when facing potential criminal charges. The consequences of a criminal conviction can be far-reaching with negative effects for years to come. I always advise clients to speak with an experienced attorney before speaking with anyone else regarding their cases. Contact me today for a free initial consultation.

If you or a family member has been charged with a criminal offense of any kind, consulting an experienced criminal defense lawyer could be your best chance of getting the charges reduced or possibly even dismissed.

Protecting You From California’s Three Strikes Law

California is a three strikes state. If you have already been convicted of a felony, you need an attorney who understands how high the stakes are for a potential second or third ‘strike’ against you. I will do everything possible and pursue every strategy to help you avoid a strike against your record.
