Jasen Bodie Nielsen

About me

I grew up in Ventura County, graduating from Westlake High School, and still have family in the area. I currently live in Santa Barbara, and focus my professional efforts on defending people who have been arrested Santa Barbara, Ventura, San Luis Obispo and Los Angeles counties. I have handled thousands of cases, first as a prosecutor with the Ventura County District Attorney's Office, and now as a criminal defense attorney. Most of my experience has involved cases of Driving Under the Influence, Driving on a Suspended License, Drug Possession, Hit and Run, Resisting Arrest, Domestic Violence, Petty Theft and other misdemeanor and felony matters.


When you call, you always speak directly to me, and I always personally handle every aspect of your case. I pride myself not only on aggressive representation of my clients but also on my customer service. Your phone calls will always be returned promptly and I will always make myself available to meet with you and answer any questions you may have.


I have an established track record of achieving excellent results and a history of satisfied clients. If you or a loved one have been arrested for a DUI or another criminal offense in Ventura, Santa Barbara,, Los Angeles or San Luis Obsipo counties, please give me a call or send me an email to put my experience, knowledge and determination to work for you.




Jasen B. Nielsen, Esq.
