Why working at PHO is important to me:

"PHO is the perfect base for a researcher that wants to have a real impact on the health of Ontarians. At PHO we interact with a wide range of health workers, clinicians, and researchers from across the province, so our research stays grounded and is swiftly translated into practice and policy."
