Widely recognized for trial excellence during his past 50 plus years of practice, Dan represents both plaintiffs and defendants in their complex commercial litigation and disputes. He was the 2010-2012 State Chair of the American College of Trial Lawyers (ACTL) and served as Chair of the national ACTL Jury Committee. He is a fellow and past state Chair in the International Society of Barristers.
Dan’s background includes litigation involving securities, corporate governance, energy, and general business issues. He regularly represents clients in cases involving the jurisdiction of U.S. courts over international transactions, disputes, and enforcement of judgments.
The defense of securities class actions and derivative claims is a particular area of achievement for Dan. He represents clients regionally, nationally, and internationally. Dan’s IP litigation experience includes enforcement of high tech firms’ noncompetition and trade secrets agreements.
Dan frequently serves as a mediator or arbitrator in commercial and other complex disputes. His listings in Best Lawyers in America include ADR services. In addition, he regularly testifies as an expert witness on attorneys’ fee issues.
Following law school, Dan served for four years as a captain in the U.S. Army’s Judge Advocate General (JAG) Corps.
A prolific writer, Dan has authored more than 20 CLE articles on substantive areas of the law and trial practice techniques, and served as co-editor of the 2012 two-volume Oregon State Bar CLE Oregon Civil Pleading and Practice.
Throughout his years of practice, Dan has received accolades from the Oregon and national legal community for his litigation practice. In October 2018, the Portland Business Journal featured Dan as a giant in Oregon corporation litigation. In recent years, Dan has added author to his credentials, first with the publication of his memoir Farm Boy: Growing up Progressive in Rural America. In Farm Boy, Dan reflects on growing up on a Montana farm established by his immigrant grandparents, mixing lighthearted stories of farm life with his brothers and sisters with thoughtful commentary on such charged social issues as immigration and rural development that resonate with today’s societal conversations. Most recently, Dan published the legal thriller The Devil’s Workshop, set in Portland Oregon, following the adventures of overweight and depressed attorney Tubby Ellis and his comrades as they go to battle against the largest firm in town – the one that recently fired Tubby. Both books are available digitally and in print through amazon.com.
Dan is also a songwriter and lead singer for a country western band.
