Who Is Matthew Leyba

Matthew was born and raised in Salt Lake City, UT.  After graduation from the University of Utah, he decided to attend Gonzaga University School of Law on scholarship.  During his time in Spokane, he developed an interest in criminal defense, in particular, DUI Defense.  As a second-year law student, he interned at the Spokane County Public Defender’s Office and developed a love for criminal defense work.

After graduation and in the summer of 2006, Matthew left Spokane to work in Seattle at one of the largest criminal defense firms in the State. While there, he represented thousands of clients who were accused of committing a wide variety of criminal offenses.  It was during this time, that he really fell in love with DUI Defense and built his reputation as a skilled trial attorney and a tireless advocate for his clients.  Matthew litigated more trials during his first four years as an attorney than most attorneys litigate during their entire career.  His success in the courtroom led him to open his own practice.

Matthew is an NHTSA qualified administrator of the standardized field sobriety tests, the same tests every trooper and police officer is trained to administer.  Having litigated over 100 jury trials to verdict, he is comfortable and confident in the courtroom.  His practice is devoted 100% to litigation.  What does that mean?  Matthew is fearless and if the prosecution doesn’t offer a deal his client wants to take, he will take the case to trial and present the best defense possible.
