I am a lifelong resident of Clark County, WA and a member of both the California and Washington bars. I have been exclusively practicing criminal defense since 2009 with an emphasis on DUI, domestic violence and miscellaneous misdemeanor offenses. As an associate to my father, Steven Thayer, I feel very lucky to benefit from his experience and mentorship and take pride in the work we do together for our clients.

Jacy Thayer DUI Slayer!
Jacy Thayer is praise-worthy attorney who I originally retained for a DUI in 2015. She was able to move my trial out so I could take a vacation. She clearly explained that the DOL was different from the courts and still represented me when I got a Driving while Suspended however she was able to get it Dismissed. She has been a continual resource for questions regarding travel, deferred program compliance procedures. Today November 28th, 2017 she just advocated on my behalf when I was at an impasse with my corrections officer who was fighting my travel plans. Back in May when I represented myself the State wasn't going to allow my request to travel but did conditionally. (I had to submit a breathalyzer test in court and the judge told me to UA the day before my trip and the day after my return.) Today with Jacy Thayer's expert knowledge of deferred procedures she got me off of the colorline and made it apparent that I was never required to request permission in front of a judge and that I was getting bullied by my PO. I think the judge thought so too as he had no record that I should have to go in front of a judge to get permission yet this was the 3rd time I was doing so. Jacy Thayer takes a tough and knowledgeable approach and demonstrates good client-side manor; that comes from divine understanding of the concept that just because you can do something doesn't mean you should. In my case made her see through the run around I was getting even if I couldn't see it because I didn't know what was normal. Hire Jacy Thayer she will see it through. She answers emails in a timely manor. She gets results that are better than what you would be facing hiring someone else or representing yourself. I probably could have received some secondary charges but did not thanks to her ability to articulate legally and concisely a clear path for her client to not waste the court's time. She is a valuable defense.

Best Lawyer you can ask for
Let me start by saying if you're looking for legal representation, Jacy is absolutely the lawyer to see. I went through the ringer during a two year ongoing battle with a very public case, and Jacy was there every step of the way to guide me with her knowledge in the field and experience. She kept calm, cool and collected throughout the process, even when things were looking to be difficult. I was referred to her after working with her father, Steve Thayer. I was lucky enough to receive counsel from both parties, and they proved to be indestructible. Jacy's diligence and work ethic are among many of her superb qualities, but most of all I actually felt that she was invested in my case and truly cared. She went above and beyond in several aspects, including dealing with evidence, letting me know what to expect with trial and continuously updating me throughout the process. I thoroughly believe that Jacy could take on any case and have the upper hand, I couldn't give her a higher recommendation.

above and beyond
Jacy went above and beyond. I always felt at ease knowing she was handling my case. Kept in very good contact with me by letting me know what exactly I needed to do to stay ahead of the game. Walked through every step of the way with me. I would highly recommend her. Thank you for making this process easier for me.

Experienced and Present
Jacy presented herself in a very approachable and experienced mannner. While I was an inexperienced basket-case of nerves, she managed my case successfully, with my best interests as her goal. Her office sent me appointment reminders, she was available by email for questions, explained processes thoroughly. I appreciate Jacy's work on my case during this stressful time. t

Best of a bad experience.
Jacy made the best of my bad choice and experience. She was not only professional but made me feel comfortable in what can be an intimidating situation. She was always genuine and I was convinced she truly had my best interest at heart. I was happy with the results and would recommend her to anyone.

One of the most professional, knowledgable and reliable lawyers my husband and I have ever worked with
Jacy not only is informative, knowledgable and reliable, she made us feel completely comfortable throughout our whole experience and was very empathetic towards our situation. She has passion and heart which clearly comes through all of the work that she does. She has represented my husband more than once with DUI and other various charges. She guided him step by step through the process on how and where to take various classes, and also got him the best outcome on both situations we could have hoped for. I would highly recommend her to anyone!

I recommend Kathryn Thayer
Jacy Thayer has helped me with DUI, Negligent Driving, and speeding tickets. Jacy is very knowledable in all aspects of what is best for you. She keeps you on your toes and motivated to get everything done in a timley fashion so its not spread out for so long. Once I received my plea I had everything done within a week because she pushes you to get this behind you and move on with your life. I will always keep her information for anything in the future as I enjoyed her by my side to help me get through what was needed.

Need legal help? Look no further
As a Police Officer, in the Portland Metro area I found myself facing a false domestic violence charge. With the help of Mrs Thayer I was able to keep my head held high, and get through this horrible experience with a not guilty verdict! Thank you for all your hard work!!!

Are you in serious legal troubles- look no further!
As a Police Officer in the Portland metro area, I unfortunately found myself facing a domestic violence charge that I did not commit. Due to my experience in the criminal justice system, here in the Portland area I knew that if I ever need legal assistance that I would turn to the law offices of Steven W. Thayer. Well that need raised, & with the assistance of Jacy Thayer I was able to get my life back on track as I was able to prove that I did not commit the crime that I had been falsely accused of.
