I have practiced law in Snohomish County for over 35 years. I have served as a judge pro tem, commissioner pro tem, and arbitrator in the Snohomish County Superior Court for over 25 years. I'm a member of the Washington State Bar Association, and the Snohomish County Bar Association, and am admitted to all of the Washington courts, including the Washington Supreme Court, and all the federal courts, including the US Supreme Court. I've been a member of the board of trustees for the Snohomish County Bar Association and the judicial liaison. I am a founding member of the ADR section of the Snohomish County Bar Association. I have been a mediator for over 20 years. When I'm not practicing law, I'm skiing, golf, biking, and/or cheering on my alma mater, Notre Dame!

Divorce and separation Attorney | Aug 10
Relationship: Worked together on matter
"I endorse this lawyer's work. I have seen Mr. Sullivan work tirelessly in the face of significant obstacles to protect and advance his client's interests. Mr. Sullivan represented a defendant in a family law matter and I represented the special master in the same case. I was repeatedly impressed with the manner in which Mr. Sullivan advanced his client's interests and also his preparation in all matters. Jeanette Bowers Weaver"
