About me

As a criminal defense attorney I have successfully defended DUI's, felony assaults, burglaries, and firearms charges.  


From 2002-2008 I worked as a Deputy Prosecutor in Grant County.  In five years I personally prosecuted over 8000 criminal cases and seized homes, cars, jet skis, and bank accounts worth over $700,000.  The above picture was taken in 2007 standing next to a DEA A-Star that I got to fly, the Columbia river at Vantage is in the background.

  • Peter John Marek

    Lyliane has a huge advantage over most criminal defense attorneys having spent six years as a prosecutor. "They know that she knows what they know". Knowledge of both criminal law and procedure is excellent and evident in her pro bono contributions. Client reviews are stellar. READ THEM? Do yourself a favor and schedule a consultation.

  • Aaron Lukoff

    I endorse this lawyer because she is smart and aggressive. She looks for the win in every case. If you have an issue in Eastern Washington. Hire her and her partner Nathan. They are both good folk.
