Cassandra L Stamm

About Me

     A prosecutor handling a case of mine recently justified an extremely favorable settlement offer based on what he called my 'scorched earth' tactics.  I thought that was a bit of an overstatement but perhaps it was not too far off the mark.  In another case, my client (a retired FBI special agent) told me he thought I was really sweet at first but then learned that I was a 'real pitbull' when it came to fighting for him.  Taken together, I think these comments sum up a lot about me and my practice.


     I work very hard for my clients.  I examine every angle in each case and when I find the weak points in the prosecution's case, I grab on and refuse to let go.  If you are being forced to defend yourself against a serious criminal charge, having someone like me on your side is an absolute must.  Give me a call and let's see if we can work together (206) 264-8586.

    I have observed Cassandra litigate very complex and tough cases in Federal Court and I can say without hesitation that she is very articulate, smart and effective with her arguments. Ms Stamm has lots of respect from colleagues in her field of practice as well as judges at all levels
