We are more than 3,500 public health care and health systems professionals driven by a passion to improve health services and outcomes for all. Our goal is to ensure all individuals can live their best and healthiest life, regardless of age or circumstances.

For 45 years, JSI has been at the forefront of global public health. We collaborate with government agencies, the private sector, and local nonprofit and civil society organizations to identify and implement solutions to public health and health care challenges.  These partnerships improve the quality, accessibility, and equity of health systems and lead to better health outcomes.

We work within communities to ground our approach in a deep understanding of those who will benefit. While we promote using best practices and sharing solutions, we tailor strategies to each situation and seek creative options to meet clients’ needs.
