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.


  • A Ventura County DUI Client Recommends Jasen Nielsen

    “When I got arrested for a DUI with a high rate of speed in Ventura county I thought I was screwed. The potential penalty that I was facing was 60 days in Ventura County Jail on top of all the other fines and fees (even though it was my first DUI). I ended up hiring Jasen Nielsen to help me out and I am very glad that I did. He didn’t make a bunch of false promises to me saying that we could get me off completely free and clear, but he told me that we would be able to help me take accountability for what had happened in the best possible way. He did exactly that! Every step of the way Mr. Nielsen kept me informed about what was going on with my case and what needed to be done. He was always available if I had any questions and he made my whole situation SO MUCH EASIER to handle. I was able to get my restricted license for work very quickly and Mr. Nielsen attended all of my court dates for me, saving me time, gas money and headaches. At the end of the day, they somehow missed charging me with anything related to the excessive speed and I was charged with a first time DUI! On top of that, Jasen was able to get me Credit Time Served for the 48 hours that I was supposed to serve resulting in NO JAIL TIME for me!! I was blown away by how well Attorney Jasen Nielsen handled everything and would recommend him 100% to anyone else that finds themselves in the unfortunate position of having to deal with a DUI.” Read On

  • “My experience with Jasen Nielsen”

    “I had the misfortune of receiving a DUI in Ventura County in 2008. Prior to this, I had never had an encounter with the law or legal system with no prior record, so i was a fish out of water when it came to knowing the proper steps to take in order to tackle this overwhelming charge that I was now facing. Initially, I was referred to an attorney with the promise that I would be in good hands and well represented. Thousands of dollars later, I was disappointed to learn that the attorney I had originally hired was nothing more than a money hungry, scum bag who could care less about me or my case. I decided to fire that attorney, which ultimately ended up being the best decision I ever made because it led me to Jasen Nielsen. Admittedly, I was a bit trepidatious about hiring someone new and somewhat reluctant to spend the money because of the horrible experience I just had with my previous attorney. I had a lot of anxiety before meeting Jasen, but as soon as I stepped foot in his office, my fears were almost immediately diminished. Jasen made me feel comfortable, at ease, relaxed, and confident, all while maintaining absolute professionalism. He never promised me anything he could not deliver, and that spoke volumes to me in terms of his character. Jasen is not one to sell or push his services onto you, as I learned, his services speak for itself. Jasen is incredibly knowledgable, dependable, honest, and trustworthy. He cares about his clients, and he fights hard for them. Never once in the three years he represented me did I feel like I didn’t know what was happening with my case. He attended every court appearance, followed by an immediate phone call, answered all of my questions and or concerns (and there were a lot of them), constantly called to make sure I always knew where I stood in terms of my case and to make sure I was following through on what I needed to fulfill on my end. He walked me through the terms of my probation, and even accompanied me to the probation office to make sure my forms were arriving on time and to ensure I was fully aware of every detail involving my probation. Jasen went above and beyond for me, and renewed my faith that there are great attorneys out there who do have your best interest at heart. There were times that I slipped up during my time on probation, and Jasen was not only there to talk me through it, he was physically in court the next day, if it was required, sometimes with less than 24 hour notice, to prevent the court from violating me. While I know he had many more cases he was handling, Jasen always made me feel that I was the only case he was representing because I always had his undivided attention. Since 2008, when someone I know asks me if it is worth spending the money to hire an attorney, I always reply, ‘only if you hire Jasen Nielsen.’ Of course you need an attorney for a serious charge like a DUI, but Jasen fights extremely hard for his clients to ensure they receive the most appropriate sentence possible. Even after my case was over, he continued to call to make sure I was doing okay and nothing new had come up, and he always reassured me that if I had any questions or needed anything, he was just a phone call away. I only wish I would have hired him from the beginning, it would have saved me a lot of money and a tremendous amount of stress. You will not regret a dime you spend on his services, and you will be thankful everyday that you have him on your side and are not doing this alone.” Read On

  • “My exact words… shared”

    “What i asked him for was an admitted “long shot” as defined by the both of us… he gave me a great deal to appear on my behalf as he was aware of my expensive legal let down with another attorney and handled my case PRECISELY as he said he would. Ultimately with the exact result he forecast. This is the EXACT email i sent him…” ‘Just wanted to say, “thank you, again” for your offer and your time on my case. as I seem to have plenty of time to sit and think lately, I just wanted you to know how very important follow through and even loyalty (especially in the “friend” realm) have become to me. Quite simply, to get “the call” from you “when you said i would” meant a lot. Of course I dreamed of a different outcome as well, but wanted to reassure you that I am most pleased with my interaction with you as you were a breath of fresh legal air that I really haven’t seen a lot of despite the $$ thrown around. Please take comfort in the fact that I will, on that alone do whatever I can to push business in your direction and thank you again for your valuable time.’ Read On

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.
