Gardner's Office The City of St. Louis Circuit Attorney Office (CAO) is committed to the responsible exercise of its prosecutorial discretion in ways that best serve our diverse community. We do so by supporting and advocating for crime victims and their families, holding individuals who harm others and commit crimes accountable, and preserving and protecting the rights of the accused. It is our mission to pursue justice fairly, firmly, and ethically, and to help create safe and livable communities for everyone while maintaining the trust and respect of those we humbly serve. We are also dedicated to pursuing innovative alternatives to traditional prosecution that include embedded therapeutic programs designed to address the root causes of criminal behavior. As an office, we highly value hard work, teamwork, and a healthy work-life balance.
