About Jason S. Newcombe
Jason S. Newcombe is a Washington State DUI defense attorney with more than 30 years of experience representing individuals charged with driving under the influence. He tried his first DUI as a prosecutor in 1996. Over the course of his career, he has built a practice focused extensively on helping people navigate, challenge, and successfully fight DUI charges at every level. Jason is a top rated criminal defense lawyer and has been repeatedly recognized as a Washington State criminal defense Super Lawyer. Jason also enjoys a perfect 10.0 rating on both Justia.com and Avvo.com. On his Avvo profile, he is rated as "Superb". He has also earned numerous Client's Choice Awards on Avvo. And, he has been recognized as a Martindale-Hubbell Client Champion Platinum award winner. He understands what a DUI charge means to every one of his clients, on a personal level. Washington State’s DUI laws can be harsh, even draconian. The mandatory minimum penalties required to be imposed after a conviction can be life altering. During these times, it’s important to have a steady hand at the wheel when rough water hits. Jason and his team bring decades of DUI experience to every case. He knows that a drunk driving arrest is not just a legal issue. It is a deeply personal and often overwhelming experience that can affect a person’s license, career, finances, and future. From the moment a client walks through his door, Jason’s focus is clear: protect their rights and pursue the best possible outcome. Background and Life Outside the Courtroom Long before becoming an attorney, Jason developed discipline and resilience as a three-sport athlete in high school, competing in water polo in the fall, swimming in the winter, and baseball in the spring and summer. That year-round commitment required focus, endurance, and the ability to perform under pressure, which are qualities that continue to define how he practices law today. Outside of his legal work, Jason remains deeply connected to the outdoors. Living in the Pacific Northwest, he takes full advantage of the environment by skiing in the winter, biking and hiking local trails, paddle boarding, fishing, and spending time on the golf course. These activities help him stay balanced and focused, allowing him to bring steady energy and a clear mindset to every case he handles. That same consistency and preparation carry directly into his work defending clients facing DUI charges. Extensive DUI Experience—From Both Sides of the Courtroom Jason brings a unique and powerful perspective to DUI defense. Early in his career, he worked as a DUI prosecutor, giving him firsthand insight into how the State builds and presents DUI cases. Now, with decades of experience on the defense side, he uses that knowledge to anticipate prosecutorial strategies, identify weaknesses, and develop effective defense approaches for his clients. Over more than 30 years, Jason and his team have handled thousands of DUI and other criminal driving related cases in courts throughout Western Washington, including Seattle, Tacoma, Bellevue, Everett, Olympia, Bellingham, Bremerton, and surrounding jurisdictions. Jason handles DUI cases throughout all Western Washington District Courts and Municipal Courts. His extensive courtroom experience allows him to navigate the legal process efficiently and effectively at every stage. Every DUI Case Can Be Successfully Challenged Jason strongly believes that every DUI case can be contested and fought on some level. No two cases are the same, and even small details can make a meaningful difference in the outcome. He carefully analyzes every aspect of a case, including: • The legality of the initial traffic stop • The administration of field sobriety tests • The accuracy and reliability of breath or blood testing • Whether law enforcement followed proper Washington Administrative Code and Revised Code of Washington procedures • Potential violations of constitutional rights By taking a detailed and strategic approach, Jason works to uncover opportunities to challenge the State’s case and position his clients for the strongest possible result. A Determined Advocate for Clients Facing DUI Charges Jason is known for being a focused, persistent, and determined advocate. He understands what is at stake in a DUI case and approaches each one with preparation, intensity, and attention to detail. Whether negotiating with prosecutors or representing clients in court, he is committed to standing beside his clients and fighting for their future. He takes pride in being accessible, straightforward, and responsive—ensuring his clients understand their options and feel supported throughout the process. Education and Professional Recognition Jason earned his Juris Doctor from Boston College Law School, graduating summa cum laude, placing him among the top 5% of his class. He completed his undergraduate education at the University of Oregon Honors College, where he was a quadruple major, earning degrees in History, Management, Marketing, and Finance. He has received recognition from respected legal organizations, including: • Super Lawyers – Attorney Profile Recognition • National Trial Lawyers – Top 100 Trial Lawyers • National Association of Distinguished Counsel – Top 1% • Martindale-Hubbell AV Preeminent Rating & Client Champion Platinum Award • Avvo “Superb” Rating and Client’s Choice Award • Expertise.com – Best DUI attorneys in Tacoma • Best of the Best Attorneys – Top 10 DUI • Lead Counsel Rated • BBB A+ Rating He is also a member of the National Association of Criminal Defense Lawyers, The DUI Defense Lawyers Association, and the Washington Association of Criminal Defense Lawyers, reflecting his ongoing commitment to DUI law and defense strategy. Helping Clients Move Forward After a DUI Jason understands that a DUI charge can feel like a life altering event. In most cases, it doesn’t have to be one. More importantly, it certainly doesn’t have to define your future. With more than 30 years of experience, a background as a former DUI prosecutor, and a belief that every case can be challenged, he brings both perspective and determination to every client he represents. His goal is simple: to fight for the best possible outcome and help his clients move forward with confidence.
