What is Primary Health Care?

Basically, when you go to the doctor - that's us. Primary health care is the professional health care you receive in your community, usually from your GP or practice nurse. Your GP leads a team of health professionals including nurses, dietitians, pharmacists, psychologists and other health workers, who work together to prevent you and your family from getting sick.

Marie Simpson

Communication lead

Marie has worked in communication roles in New Zealand and the UK. She worked across a few different sectors but quickly discovered she isn't built to sell widgets, she needs true meaning in her work so she started working in a health focused not-for-profit environment - ten years later it still gets her out of bed in the morning.

As the self-confessed style and brand police, Marie's role at Pinnacle MHN is to make sense of the huge range of information that needs to go out the network every week. Her key areas of interest are communications strategy and planning, digital communication and above all celebrating and recognising heart-warming and life changing success stories.

Marie hones her time and project management skills by trying to keep up with the hectic demands of two kiddos. In her downtime she sometimes attempts to be a runner, but mostly she'll be on the couch with her nose in a book or trying to tame her ambitious watch list on Netflix.
