Kari also oversaw the launch of Access Ava, a digital service providing free, straightforward legal information for all.
Systemic change is at the heart of Kari’s work. As a respected spokesperson and campaigner, she frequently appears in TV and radio interviews to highlight the need for long-term reform.
