After more than 30 years as a successful litigation attorney, Colleen Barrett is now dedicating her skill, background and experience to bringing parties together to reach a fair resolution of disputes. Plaintiffs want a mediator who will listen and make them feel they have been heard. Defendants want a mediator who understands value and risk. All parties want a mediator who aids them in looking at the strengths and weaknesses of their case and in overcoming obstacles that stand in the way of a durable resolution to their dispute. Colleen is that mediator.

Colleen made the jump from successful trial lawyer to committed and effective mediator and has not looked back. Since November 2013, Colleen has worked exclusively as a neutral, mediating a wide variety of cases to a resolution.

Aside from her 30 years of experience as a litigator, Colleen added tools to assist her in helping the parties keep control of the outcome of their cases through formal training as a mediator at both the University of Washington Law School and, more recently, at the Strauss Institute for Dispute Resolution, the highly regarded program offered through Pepperdine University Law School.

Colleen's legal experience began with 8 years at the Seattle City Attorney's office where she tried hundreds of criminal cases, provided legal advice to the mayor and City Departments, and tried personal injury and employment law cases. Since 1988, Colleen has handled complex litigation, including professional liability and medical negligence, defamation, insurance coverage and bad faith, construction defect, land use disputes, and represented both plaintiffs and defendants in personal injury, wrongful death and employment litigation. She has also handled appeals and done presentations on negotiation strategies, effective mediation presentations, trial practice and insurance law.
