She is principally known for her work in the field of slavery and human trafficking, advising upon the legislation and successfully prosecuting a number of these difficult and high profile trials with “consummate skill”.
Before coming to the Bar, Riel trained and worked as a theatre director, which not only informed her understanding of the psychology of witnesses and defendants, but also helped make her an exceptionally jury friendly advocate.
