Who is Matthew Leyba

I was born and raised in Salt Lake City, UT.  After graduation from the University of Utah I decided to attend Gonzaga University School of Law on scholarship.  During my time in Spokane I developed an interest in criminal defense, in particular DUI Defense.  When I was a second year law student I interned at the Spokane County Public Defender’s Office.  While there I represented individuals accused of DUI and the Spokane DUI Court.

After graduation and in the summer of 2006, I left Spokane to work in Seattle, Washington at one of the largest criminal defense firms in the State. While there I represented thousands of clients accused of a wide variety of criminal offenses.  It was during this time that I really fell in love with DUI Defense and built my reputation as a skilled DUI attorney and a tireless advocate for his clients.  Heck I litigated more trials during that span than any other lawyer I know of.  Most often winning favorable results.

Why did I decide to start a DUI law practice

In 2010 I wanted to challenge myself even more but still wanted to be involved in DUI Defense.  After much thought and planning I decided to start my own law practice and opened Leyba Defense PLLC.  I decided my firm was to focus on DUI Defense and that’s it.  I honestly felt at the time, and I still do in order to become the best DUI Attorney in Seattle I can’t waste my time dealing with other types of criminal matters.  All I do is DUI Defense and because that’s my sole area of practice I am very good at it.

I’m a NHTSA qualified administrator of the standardized field sobriety tests, the same tests every trooper and police officer is trained to administer. I’m also an experienced trial attorney, having litigated over 100 jury trials to verdict. My practice is devoted 100% to litigation.  What does that mean?  If the Prosecutor won’t give us the deal we think is fair then we will go to trial and I will do everything humanely possible to win at all costs.

Additionally I’m a frequent lecturer on DUI and criminal trial related topics.  Most recently I was a guest speaker at the Washington Young Lawyers Division Trial Advocacy Program where I shared my expertise and knowledge in jury trial preparation and organizational skills.  I’m rated a perfect 10 out of 10 by Avvo.com among Seattle DUI Lawyers, and I haven been repeatedly named a Rising Star in the area of DUI Defense by Seattle Met Magazine.  This means I’m extremely good at my job.

Why am I the Right Seattle DUI Attorney for you

I have seen the inside of a courtroom almost every day during my career as a criminal defense attorney. As a result of this experience I have seen and been placed in almost every scenario that may arise during the course of a case. Whether it’s negotiating with the prosecutor, speaking to a judge, or persuading a jury, I have the necessary skills to get you the best results possible.  I firmly believe that.

Wherever the course of a case take me, I guarantee I will never be out worked by the Prosecutor, I will always be the most prepared attorney in the courtroom, and I will do everything possible to get the best outcome.  I guarantee that!
