David Allen, a member of the Washington and Massachusetts bars, is a partner at Allen, Hansen, Maybrown & Offenbecher, P.S. Allen has practiced in Washington State since his graduation from law school in 1969.  He limits his practice to criminal defense, both trial and appellate practice, and representing lawyers and judges in disciplinary proceedings.

Allen has had very good outcomes defending criminal cases.  For example, from 2006 through 2016 Allen tried 21 serious criminal cases, which included charges of homicide, assault, sexual assault and fraud in State and Federal courts.  Allen won 17 of these cases (a win includes a not guilty verdict or a hung jury where charges were then dismissed by prosecutor) while losing just 4.  Allen has kept track of his results over the years and has won a substantial majority of his over 250 jury trials.  While this is no guarantee of a successful outcome in a future case, it is a measure of his effectiveness as a litigator.

Allen has also had good success in either convincing prosecutors to decline filing charges or having charges dismissed prior to trial.  Recent cases where charges were dismissed prior to trial after defense investigations and motions as well as a list of significant trials are listed below.


Allen has been continually listed in The Best Lawyers in America; Seattle Magazine's list of top lawyers; and Washington Law and Politics magazine "Super Lawyers" since the early 1990ís when these listings began. In January 2005, he was listed as one of Seattleís "Top" 152 lawyers, in all fields and in December 2006 and again in 2008 he was listed as one of the top eight criminal lawyers by the Seattle Magazine. He was selected by his peers in 2010 as the Single Best Criminal Defense Lawyer in the State of Washington. (Best Lawyers in America Annual Survey, Seattle Business, January 2010 issue).

He was the recipient of the Washington Association of Criminal Defense Lawyer's William O. Douglas Award in 1995, for "extraordinary courage and dedication to the field of criminal law."


Allen graduated from Tufts University in 1966 and Boston University School of Law in 1969.


Allen began working for Seattle Legal Services as a staff attorney in 1969, where he handled a variety of cases, including class action prisoner civil rights cases and civil Indian treaty fishing cases. He also defended flag desecration cases as an ACLU cooperating attorney and volunteered his time representing Puyallup and Nisqually tribal members charged with crimes resulting from the exercise of their treaty fishing rights.

In 1974, Allen joined the Seattle/King County Public Defender's Office as a staff attorney and assistant felony division supervisor. During his five years with the office, Allen handled serious felonies and appeals.

Allen entered private practice in 1979, and was soon joined by Richard Hansen, with whom he had worked at the Public Defender's Office. In forty-seven years of practice, Allen has tried more than 250 criminal jury trials in both state and federal courts, as well as handled serious criminal appeals. Besides his criminal defense and appellate practice, Allen also represents attorneys and judges in disciplinary and ethics matters.



Allen has served on many bar association committees and was chairperson of the Seattle/King County Barís Criminal Law Section, the Barís Prison Reform Section and is a founding member of the Washington Association of Criminal Defense Lawyers.

Allen has lectured at over 100 continuing legal education seminars (a list of representative seminars available on request), and has been a lecturer in criminal procedure at the Seattle University Law School.

In 1973 Allen served as a volunteer attorney in South Dakota for Native Americans charged in the Wounded Knee demonstrations. He has done volunteer legal work for Northwest Native American tribes and the ACLU. Allen also volunteers his services to the Innocence Project Northwest, an organization of concerned attorneys and law students who assist wrongly convicted individuals.
