Why working at PHO is important to me:

"Public Health Ontario has grown and evolved into one of this country’s public health leaders and allows for me to contribute credible scientific and technical advice to help advance public health immunization research and practice across the province. I feel fortunate to be a part of a centre of expertise dedicated to protecting and promoting the health of all Ontarians through the application and advancement of science and knowledge."
