About me

The only Snohomish County attorney named Superlawyer for representation in the area of DUI and criminal defense.  I am a 1987 graduate of the University of Massachusetts at Amherst with a Bachelor of Arts in Journalism and Political Science.  In 1990 I earned my Juris Doctorate from Western New England College School of Law.

Upon admission to the Washington Sate Bar Association, I worked as a public defender in Snohomish County gaining extensive trial experience in felony and misdemeanor cases, including, manslaughter, assaults, sexual offenses, burglary, theft, arson, harassment, assault domestic violence, DUI, driving while license suspended and hit and run. From 1999 through 2001, I was employed as an Assistant City Attorney for the City of Seattle prosecuting misdemeanor and gross misdemeanor cases. In addition to my criminal practice, I represents plaintiffs in personal injury litigation including motor vehicle accidents, premises liabilty, sexual assault and assault, .

Since entering private practice in 2001, I have served as a judge pro tempore in district and municipal courts in Snohomish County. I am admitted to practice in Washington State Courts and Federal Court for the Western District of Washington and I am a current member of the King and Snohomish County Bar Associations; the Washington State Trial Lawyers Association; Washington Association of Criminal Defense Lawyers; the Washington Defenders Association; and a former member of the National Association of Criminal Defense Attorneys and Washington Association of Municipal Attorneys.
