Healthy Minds Matter


HMM Health exists to provide the community of the Whitsundays with high quality, accessible and ethical mental health services. Dr Catherine McQuoid-Mason and Nathan Harriott have practiced in the region for a collective 10 years and have developed their practices on these same principals.

We offer services to children, adolescents and adults with a variety of psychological, emotional and/or behavioural presentations.
