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.

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. Click Here To read more about DUI Defense.
