Asa represents clients in family law matters, such as divorces and child custody disputes, because he finds that helping people through some of their most difficult and trying life situations to be incredibly rewarding. When Asa was young, he was raised primarily by his mother after his parents split up. His parents worked hard to ensure they could work together and do what was best for their child. While they never stopped working together, it was often a difficult process – from holiday disputes to child support issues, which has given Asa a deeper understanding of the clients he represents. Asa seeks an amicable resolution where possible in order to reduce conflict, maintain healthy co-parenting relationships, and reduce costs for clients while obtaining the best results possible. However, Asa enjoys litigation to hold others accountable as he understands that many people simply refuse to do the right thing.

In his free time Asa enjoys spending time with his wife and dog, spending time in the great Washington outdoors, trying new food, reading science fiction or American history books, and watching all kinds of movies.


Asa is licensed to practice law in Washington and Idaho, as well as federal court in the Eastern District of Washington. He is a member of the Washington, Idaho, and Eastern District of Washington bar associations.
