If you are facing a DUI charge in San Diego, you need an experienced attorney to defend your case and work to minimize any potential adverse long-term effects.

Former Veteran Prosecutor Dedicated To Your Defense
I bring my training and experience as a former prosecutor to each case The Law Offices of Mark Deniz APLC takes. With more than 10 years of experience handling DUI cases as a defense attorney, I have a unique perspective from both sides of the courtroom. From day one, I build your case based on strong, mitigating evidence to present to the prosecution and judge at the time of your first court date – roughly six weeks following your arrest. This strategy can help increase the chances of securing reduced charges.
Protect Your Driver’s License
One of the worst parts of a DUI arrest is the potential to lose your driving privileges. If convicted, your license will be suspended for at least six months. Suspension time increases if multiple convictions occur within 10 years. It is crucial to secure an aggressive San Diego attorney experienced with DUI defense immediately following your arrest to protect your driving privileges.
Protect Your Future
Drunk driving charges can have serious consequences, including jail time, fines, and a permanent criminal record. But with the right defense strategy, you can minimize or even avoid these penalties altogether. As your attorney, I will work tirelessly to build a strong defense on your behalf. I will investigate the circumstances of your arrest, challenge any evidence against you, and negotiate with prosecutors to seek a favorable outcome.
Here are some of the services I offer to clients facing drunk driving charges:
- Legal advice and representation throughout your case
- Defense against a wide variety of DUI charges, including refusal DUIs, repeat DUIs, military diversion DUIs and DUI hit-and-run
- Negotiation with prosecutors for reduced charges or alternative sentencing
- Expungement of your criminal record, where possible
