JSI is a healthcare consulting firm that helps health organizations achieve their desired results. JSI meets organizations—whether health, clinical, or community-based—where they are to develop programs that engage participants, reduce the burden on providers, enhance quality of care, integrate services across the continuum, and reduce costs. JSI helps organizations facilitate the engagement that is necessary to increase health status and transform health systems.

JSI’s services are evidence-informed, culturally targeted, and designed to help organizations build their capacity to improve and expand their public health and health care services. JSI’s overall approach is collaborative, mindful of an organization’s needs and priorities from a practical, budget-conscious perspective. JSI draws on implementation science principles and evidence-based quality improvement strategies to guide organizations through system-wide change in support of improved client, patient, and community-level outcomes. The goal of JSI’s technical assistance and capacity building services is to produce sustainable change that enables organizations to better achieve their missions.

As part of JSI’s work with the Central New York Care Collaborative (CNYCC) (A Regional partner in the NYS DSRIP Program), JSI convened an expert panel of primary care providers, cardiologists, pharmacists, and community-based organizations and developed a series of principles, evidence-based guidelines, clinical protocols, and tools to inform the CNYCC’s integrated, cross-sector approach to the management of heart disease, including guidance on hypertension and diabetes. The burden of chronic disease, particularly heart disease, hypertension, and diabetes, were identified in the CNYCC’s initial community health assessment as one of the leading health issues facing the Central New York region. As a result, JSI facilitated an extensive series of full panel and small workgroup meetings. Ultimately, the guidance from this panel has been used to drive technical assistance and a broad chronic disease management plan that has been one of the most successful efforts of the CNYCC’s efforts to-date.


JSI has been working with organizations that serve diverse, often underserved and vulnerable consumers for more than 40 years. This experience has provided a unique understanding and appreciation for the importance of tailoring to the unique cultural, linguistic, and social contexts of the consumers that our clients serve. Addressing health equity and the racism, social injustices, and cultural issues that are often at the heart of existing disparities is central to population health improvement and is a focus in JSI’s approach. The core staff for MassHealth TA ensures that this awareness and consideration is woven into TA activities. A diverse pool of bi-cultural, bi-lingual staff is available to work on project teams.
