Jasen Nielsen DUI Defense Attorney.

My name is Jasen Nielsen. I am a former Ventura County Deputy District Attorney. I grew up in Thousand Oaks, graduated from Westlake High School, and my family still lives in the area. My professional practice is dedicated to representing clients who have been arrested for a DUI in Ventura County. I have professional relationships with local prosecutors, judges, and court staff, and have an excellent history of getting DUI charges reduced or dismissed.

Hiring a DUI Attorney

After you have been arrested for drunk driving, you will be bombarded with advertisements from any number of attorneys, all seeking your business. Some of these attorneys may even be qualified to represent you, but many will not. A large number of these alleged Ventura DUI attorneys will actually be from Los Angeles, and only vaguely familiar with the much harsher potential consequences of a Ventura DUI case. Nonetheless, many will send you a lengthy list of the cases they have purportedly had dismissed. Nearly every single one of them will refer to themselves as aggressive, but only a few will have the wisdom to know when to use it.

Ventura DUI Punishment: Much Misinformation

The local prosecutor's office has an army of attorneys trained to ensure that the system punishes you as harshly as possible, resulting in notoriously harsh Ventura DUI penalties, including Jail Time and/or Work Release, Fines and Fees, Alcohol School, License Suspension, Required Ignition Interlock Device Installation, Formal Probation, and more.

There is much misinformation about the potential consequences and possible enhancements if you are convicted, some of it coming from many of the attorneys seeking your business. A DUI conviction can very seriously and negatively impact many different areas of your life, and it takes an experienced attorney with a nuanced understanding of the law and the system to achieve the best possible outcome in your case. If you do not qualify for the public defender, you will be forced to accept whatever the government is offering you, usually without ever having the chance to even see the police reports.

Your License: Act Quickly

Unfortunately, you need to act quickly, as you have only 10 days to request a separate hearing with the DMV, or your license will be automatically suspended. In the event that your license is suspended, there are confusing procedures that must be followed precisely to get your restricted license as quickly as possible.

Experienced, Professional and Discreet

As a former Ventura DUI prosecutor, I know what cases to fight and what cases to mitigate, and how to help you get this horrible experience behind you with least possible consequences. I have represented hundreds of clients from all walks of life, including law enforcement officers, doctors, attorneys, nurses, and students. You may never have to appear in court, and if I cannot beat your case, I will ensure that any punishment you face will be as minimal as possible. I am always available to meet with you and will personally make all of your court appearances. When you call my office, you will always speak directly with me, and your calls will always be returned promptly.

Fair Prices, Payments Plans

I believe in offering my services for fair prices, and am happy to offer affordable payment plans. Please give me a call today to put my experience to work for you.

Recent Case Results

  • There are some cases that are easy for the government to prove according to the letter of the law - this would be one of those cases. My client was under 21 and walked straight up to Ventura County Sheriff's deputies carrying 48 beers. However, by thinking outside the box, I was able to use my experience get all of the charges dismissed. Read On

  • At the DMV hearing, I was able to attack the credibility of the Santa Maria officer who had arrested my client for the DUI. As a result, her license was not suspended by DMV. After numerous court appearances and discussions with the Santa Maria prosecutor, I was finally able to convince them to dismiss the DUI charges in exchange for a plea to a wet reckless. She did not have to attend AA meetings, saved about $1000 in fines and fees, and, most importantly, the was no court- related suspension of her license. Read On

  • The punishment sought at court in this case was 48 hours jail, 6 month license suspension, 3 month alcohol school that costs about $900 in Ventura County, $4000 in fines and fees, 3 years of formal probation, increased insurance premiums and a criminal record. Prior to court, I was able to win the DMV hearing on a technicality that would not have been successful at court. I filed a motion to suppress challenging the legality of the arrest, hoping at least in part to convince a Ventura prosecutor or judge to dismiss the case based on the unfairness of the entire situation, as the arrest itself was probably legal. After going to court numerous times and being fought by the Ventura prosecutor every step of the way, I was finally able to get the case dismissed when the arresting officer failed to show in court.
