  • Steven W. Fogg

    I strongly endorse Keith's work. I have had the opportunity to work with Keith on both sides of the fence, and I'd much rather be on Keith's side than squaring off agianst him. He is smart, passionate and a tireless worker who always seems to obtain fantastic results for his client no matter what facts he begins with.

    I endorse this lawyer's work. Keith is one of the best litigators in the Seattle area. He is professional, assertive, efficient and extremely smart. I would not hesitate to refer a client or friend to him and would certainly hire him myself if I needed representation.
