Jennifer is driven beyond the win, she wants to positively impact the lives of her clients. By providing superb yet affordable legal counsel, she defends people being abused by the system. The legal system was constructed to fairly defend all persons regardless of income, education or ethnicity. Being charged with an offense is not a crime, the crime is being underrepresented and ill-prepared to properly fight the charges.
