Executive Team

Sonic Core Values

Sonic’s Core Values were created by our staff more than 20 years ago, and act as guiding principles for how we conduct ourselves as an organisation.

SHL Core Values 2020 RGB

Our Core Values set the standard for the collegiate and supportive way in which we behave towards one another, as well as the professionalism with which we conduct ourselves in our day-to-day duties. Individually, our Core Values articulate our commitment to medical excellence. Collectively, they empower our people to deliver exceptional medical services to doctors and patients. 

Since their inception, Sonic’s Core Values have been embraced by Sonic Healthcare staff around the world as a unifying code of conduct.
