Welcome to the Law Office of Derek R. Ewin. We use our extensive experience in the local Bay Area Courts to help our clients get the best possible results in the their DUI cases.

Derek Ewin has been working in the San Francisco Bay Area Courts for nearly two decades. For almost 12 of those years, he prosecuted cases for the Contra Costa District Attorney's office. Since then, he has defended DUI cases in almost every Bay Area County including, San Francisco, Alameda, San Mateo, Santa Clara, Contra Costa, Solano, Sonoma, Napa, Monterey, Lake and San Joaquin.

Mr. Ewin has prosecuted and defended around 1000 drunk driving cases over the past 18 years. He has handled nearly every aspect of DUI law including, reviewing cases to file, negotiations, motions to suppress, motions to dismiss, plea bargaining, court trials, preliminary hearings, jury trials, sentencing and appeals. He has also handled numerous Department of Motor Vehicle (DMV) suspension hearings.

DUI law can be complicated. Something as simple as missing a deadline can result in a loss of your driver's license without the ability to have a hearing. If you set a hearing or a court date at the wrong time, your expenses can be greatly impacted. A person with limited experience can easily miss a defense or mitigating factor when reviewing a police report. An inexperienced person can actually misspeak and give a judge or DA information upon which to increase a penalty

Mr. Ewin has the experience in DUI defense to know what to say and what not to say. Even more important, Mr. Ewin knows many of the local prosecutors and judges. He has fostered a reputation of integrity and skill, and, as a result, he is treated well by Courts and DA's alike. Let him use his experience and reputation to get you the best possible result in your drunk driving case.

Serving the Greater San Francisco Bay Area

A drunk driving arrest triggers very important time limits. You need to contact Mr. Ewin immediately. Your privilege to drive could be impacted in as little as 10 days if you do not toll these limits. In some cases, if Mr. Ewin can contact the DA's office early enough, he can give the filing deputy district attorney exculpatory information that will prevent your case from being filed at all. Reduce or even eliminate the consequences of your DUI arrest by calling Mr. Ewin right away.

Don't wait. Contact us as soon as possible (24 hours a day, 7 days a week)
