Before joining the firm, Rory clerked for the Honorable James Verellen at the Washington State Court of Appeals, Division One, for two years. He analyzed more than 60 appeals from bench memorandum to judicial opinion. His clerkship gave him valuable insight into the judicial decision-making process. Rory uses that insight to offer a unique perspective to clients. Rory regularly writes on appellate issues in his appellate law blog.  You can subscribe to his blog posts for future updates.

While in law school, Rory was an extern for the Oregon Court of Appeals in the Appellate Commissioner’s Office. Before law school, Rory taught English in France for two years.

Rory impacts his local community with his commitment to pro bono service. He regularly volunteers for the Housing Justice Project in King County. Outside of the office, Rory enjoys voyages abroad (especially to France) and spending time with friends and family. Rory channels his love for basketball through his annual participation in the Spokane HoopFest basketball tournament. And when the weather permits, Rory will be found on the links working on his short game.

“Rory is beyond dedicated to the field of law. Having had the opportunity to work with him at the Court of Appeals, I witnessed firsthand his extreme work ethic and legal expertise. Rory’s unique perspective of the law and ability to effectively navigate difficult legal issues are unmatched. His vivacious personality is infectious and only an added bonus to his professionalism and practicality. Rory is a tireless and tenacious advocate that I recommend to family and friends whenever they are in search of quality legal advice. There is no one more passionate about helping you efficiently resolve a legal dispute than Rory. He is a powerhouse.”

“Without hesitation, I endorse him as an expert and man of the highest regard. Rory is one of the most intelligent people I have ever met, and his dedication, passion and drive know no limits.”

“He is the consummate professional and his clients are well served by his superior intelligence, tireless work ethic, easy-going personality, and competitive drive. I cannot recommend Rory Cosgrove strongly enough.”
