About me

My practice is currently focused on defending people accused of felony criminal charges in the MRJC.


I was interviewed by Martin Kaste of NPR regarding the implications of legalized marijuana in Washington and the establishment of a per se level for Marijuana DUI. Listen to the NPR interview.

  • Jan Phillip Olson

    I watch Peter take tough cases to trial. Cases that other lawyers would be scared to take. I am convinced he gets superb results for Clients in situations where others would simply be too intimidated.Put another way. he gets great results for his Clients because of his reputation to take tough matters to trial when necessary. However, the Client always comes first; I have never seen Peter's pride or ego get in the way. He is always looking out for the Client's best interest, while continuing to listen to the Client's concerns and desires. I have consulted with him, and found him to straightforward, practical and very aware of what works in the courtroom. He knows the judges, prosecutors, and court personnel better than anyone. Clients will find him a source of encouragement, compassion and strength.
