Run don't walk to hire Casey

If you have the good fortune to read this and have not yet hired Casey, I say RUN don't walk to any opportunity to have her represent you. Before I hired Casey, I was represented by a mediocre attorney until I realized I needed a smarter, stronger advocate. As such, I interviewed the most reput...able attorneys in town and upon meeting Casey it was apparent that she was several notches above most every defense attorney I interviewed. During our interview, she answered every one of my questions intelligently and succinctly without any evasion. I immediately wanted to hire her and since then, I was never disappointed in how she handled my case. Rather, I was impressed by how strategic she was. At all points, her predictions on how the events in my case would play out came to fruition. Casey knew how to request evidence and obtain subpoenas when the Prosecution and the "Victim" held information back. She knew when to push on the key players and when to lay back. As a result, I trusted her implicitly as should anyone who is lucky enough to hire Casey. I have had many transactions with attorneys throughout my life and trust me, it is not easy to find one who possesses Casey's combination of talents, If an attorney is a good writer, they are not always a strong in court. And finding a strategic thinker who can write or litigate well is even more difficult. It is rare to find an attorney who is a strategic thinker, strong writer and articulate in front of a judge all wrapped in one. Casey IS that attorney. My case turned out well, in the end my case was dismissed as Casey predicted. She was even slightly cheaper than that mediocre attorney I hired in the first place. As I said, RUN don't walk to hire Casey. She is truly amazing and feel blessed to have had her on my side.

Great attorney

I was falsely accused of a crime when I caught my ex-girlfriend of embezzeling my mortgage payments. From the start, Ms. Stamm took my concerns seriously and reassured me that this would ultimately be a small bump in my life. She thoroughly investigated the allegations and presented evidence to the p...rosecutor's office showing that I was the victim of someone trying to save themself. With the evidence presented, my case was dismissed, allowing me to move on with my life. I couldn't be happier with the assistance I got from Ms. Stamm.

A clear choice

Fairly new to Seattle, a family member needed a lawyer. Immediately. We contacted the only two connections we had to the city’s legal community, and both unhesitatingly referred us to Casey Stamm – noting her daunting record of success, her quick and clear-sighted intelligence, and her fierce dedic...ation to pursuing what is just. Indeed, we found her to be all that - and more. She was pragmatic but also about possibilities, deeply informed yet an uncommon teacher about the law, and starkly realistic but with a creative touch. She was also an impressive judge of character and uncompromising advocate. Given the results (which were the best possible given the variables), we have nothing but the greatest respect for Casey’s work, and we extend our deepest gratitude to her for her support and efforts on all our behalf.
