    I endorse this lawyer. As an example of Tassma Powers' excellent legal skills, Tassma and I were involved in a contentious case involving a dispute over the interpretation of contract terms and responsibilities, Tassma maintained the utmost level of professionalism while providing strong advocacy and protection for her client. Her high level of professionalism and her exceptional understanding of this area of the law served her client well.
