Athan’s practice focuses on construction litigation and contract law, real estate law, and complex commercial litigation. He advises public and private clients on various issues throughout the construction process, negotiates and drafts design and construction contracts, prepares procurement documents, and represents clients throughout the dispute resolution process in both trial and appellate courts. Athan also advises and represents clients through dispute resolution processes on various real estate and landlord-tenant disputes, and has served as a third-party neutral, assisting parties in resolving their disputes.

Prior to law school, Athan spent several years working in the construction industry.  Our clients benefit from the knowledge he gained as a construction project engineer for a general contractor and developer – he not only understands the entire construction lifecycle but speaks the same language as our clients.

Athan stays abreast of industry developments while training the next generation of leaders.  He teaches Construction Law for the University of Washington’s Construction Management program and is a frequent speaker and author on a variety of construction law related topics. Athan has served on the Executive Committee of the Washington State Bar Association’s Construction Law Section since 2012, including serving as the Chair in 2017 through 2018.  He also co-authored chapters in the Washington Construction Law Deskbook on Alternative Procurement Methods and the Contractor’s Registration Act.

Athan received a B.S. in Construction Management from University of Washington in 1994 and his J.D., summa cum laude, from Seattle University School of Law in 1999.
