Services & Fees

Because I limit my practice to DUI related actions I can give your case the personal attention it needs and deserves! I deal with your case as though it was my brother’s case. You deserve no less. Once you select me as your advocate, there is never an additional charge to talk, in fact I encourage communication as often as necessary to resolve this matter with the best possible result. Call me anytime, 24 hours a day, 7 days a week at (707) 570-0770. I offer evening and weekend appointments for your convenience and I also accept credit cards and offer flexible payment plans.

Throughout our years of successfully handling DUI cases, I’ve seen it all. I’ve successfully defended over the limit blood and breath tests, test refusals, bad driving, good driving and reckless driving or no driving at all. Whether you were stopped and arrested by the CHP or local Law Enforcement or the County Sheriff, I know how challenge the reason you were stopped and the reliability of any equipment used to test you.

My charges for handling DUI related cases would vary depending upon the complexity or simplicity of your particular case. Once you fill out the interview, I’ll give you a call and we can discuss what is involved in setting you free from this stressful situation. At that time, I will be able to give you an idea of what our service will entail and what it will cost. Typically, there is a flat fee to handle all appearances and motions and negotiations to resolve this in the best possible way without a trial.

If a trial becomes necessary to defend your case, then we will likely handle that on an hourly basis. Whatever you decide, you can rest assured that no better value can be found in representing you in this criminal case.In any case, the initial phone consultation with me is free, so there is no risk on your part-and you will learn just what your rights and options are. When we are finished, if you’re not convinced that I will be able to protect you to your complete satisfaction, then you can simply decide not to hire me. I won’t trouble you again . . . and you’ll owe me nothing.

However, If you do choose to seek the advice of another attorney, make sure you ask him or her some tough questions:

  • What motions will you file and what information will you be seeking in discovery?
  • What medical conditions can cause the breath testing equipment to give inaccurate readings?
  • What are the top three field sobriety tests recommended by the National Highway Traffic Safety Administration?
  • What is the basis of a rising blood alcohol defense?
  • What are three major defenses in a blood test case?
If the attorney you’re speaking with does have the answer to these questions, then they probably are experienced in handling DUI’s. If not, then Good Luck!

In addition, if you consult with other attorneys, ask them to show you a copy of the Driver Safety Manual which detail procedures for everything related to driver’s licensing. If that attorney doesn’t have this manual, you know he/she may not be prepared for your case.
