About Us

Building Stronger Health Systems and Healthier Communities

We are public health care and health systems consultants and researchers driven by a passion to improve health services and outcomes for all. Our fundamental goal is to ensure that all individuals can live their best and healthiest life, regardless of age or circumstances.

In pursuit of our goal, we provide innovative management consulting and technical assistance incorporating a broad range of skills. Founded in 1978, we collaborate with government agencies, the private sector, and local nonprofit and civil society organizations to identify and implement solutions to public health challenges.  These partnerships improve the quality, accessibility, and equity of health systems and lead to better health outcomes.

We work within communities and rely on local staff 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.
