Messina Madson is co-founder of the Madson Castello firm, which represents individuals in criminal law cases. Both she and law partner Kendall Castello began their careers in the Dallas County District Attorney’s Office, where Madson served as acting district attorney for 21 months. While in the role, she created the office’s Civil Rights Division, which conducts an independent investigation of every officer-involved shooting in Dallas County.

Now in private practice, she has defended police officers in shooting cases, most recently winning an acquittal on behalf of former Dallas police officer Christopher Hess, who was charged in the 2017 shooting death of 21-year-old Genevive Dawes.
