Jay Zerwekh Named New Chief Executive Officer of Castell

Jay Zerwekh has been named the new president and chief executive officer of Castell.

In the past three years Castell has helped accelerate the adoption of value-based care models, which incentivize providers to keep patients well, improve patient outcomes and their care experience, and simultaneously drive down healthcare costs.

Castell has accomplished this not only at Intermountain Healthcare, but also for other health systems, providers, and payers.

“As Castell continues to expand its network of care to help more people stay healthy, Jay brings the right combination of industry experience and leadership to bring providers and Castell’s 450 employees together to further our mission to improve healthcare for everyone,” said JP Valin, MD, Intermountain’s chief clinical officer.

Zerwekh joins Castell following a 20-year career in healthcare, first serving in leadership positions in medical group, health plan, and hospital settings, and then more than 16 years at Galloway Consulting, where he consulted health systems, hospitals, and medical groups across the country.

This experience has allowed him to understand how to best engage each type of organization involved in population health. Zerwekh has a passion for population health work and the impact it has on the overall health and wellbeing of patients and communities served under the value-based care model.

“One of the most compelling things about Castell is how attuned we are to providers. Our approach to population health and long-standing partnership with Intermountain, make Castell uniquely capable of bringing transformative, meaningful change to healthcare,” said Zerwekh.

Zerwekh holds a master’s in health services administration from the University of Michigan and a bachelor’s degree from Clark University.
