Hillary Aizenman is an experienced, compassionate, and steadfast advocate who takes a pragmatic and goal-oriented approach to her cases, with a relentless focus on achieving the best possible outcome for her clients.

Hillary graduated third in her class and as a member of the Order of the Coif at the University of Colorado Law School.  She then served as a law clerk for Chief Justice Michael Bender on the Colorado Supreme Court.
