Doug Dietzman has been named president and executive director of the nonprofit health information network eHealth Exchange, succeeding Jay Nakashima, who is semi-retiring after eight years of leadership.

Nakashima led the organization as it expanded its national footprint, modernized its technology platform, and became one of the first Qualified Health Information Networks (QHINs) designated under the Trusted Exchange Framework and Common Agreement (TEFCA).

In 2025, Healthcare Innovation interviewed Nakashima about a range of issues, including eHealth Exchange’s role at the center of an ambitious digital health pilot project in Utah to implement a statewide FHIR-based ecosystem.
 
Dietzman brings more than two decades of experience working across the healthcare ecosystem—including hospital systems, physician organizations, health plans, HIEs, and national interoperability initiatives. Most recently, he served as managing director of interoperability solutions at the Blue Cross Blue Shield Association (BCBSA), where he led interoperability strategy, policy and regulatory engagement, standards development activities, and clinical data exchange initiatives. Previously, he served as executive vice president of Michigan Health Information Network and, before that, as CEO of Great Lakes Health Connect in Michigan. 
 
While serving as CEO of Great Lakes Health Connect, he represented HIEs on the eHealth Exchange Coordinating Committee from 2018 to 2021. Under his leadership, the BCBSA joined the network in April 2025, and he has served on the eHealth Exchange board of directors for the past 18 months.  Those experiences provide him with a strong understanding of the organization's mission, its participants, and the opportunities ahead as healthcare continues to embrace nationwide interoperability.
 
“Throughout my career, I've had the opportunity to work alongside providers, health plans, HIEs, government agencies, and technology partners, all with a common goal of making health information more accessible, secure, and useful,” said Dietzman in a statement. “eHealth Exchange has earned an exceptional reputation as one of the industry's most trusted and established interoperability organizations. I'm honored to join this outstanding team and look forward to building on that strong foundation while expanding the ways we help participants improve care through trusted, standards-based data exchange.”
 
Under Nakashima's leadership, eHealth Exchange significantly expanded its national network, transitioned to its modern hub architecture, accelerated adoption of HL7® Fast Healthcare Interoperability Resources® (FHIR®)-based interoperability, established strategic collaborations across the industry, and continued its longstanding commitment to protecting patient privacy by never storing patient data or using it for secondary purposes.
 
In a statement, Nakashima stressed that Dietzman understands the importance of trusted interoperability, values collaboration, and has a deep appreciation for the public good mission that has always guided this organization. Having worked alongside Doug through his service on our board, I've seen firsthand his thoughtful leadership and commitment to bringing people together to solve complex challenges. Our participants, partners, and team will be in exceptional hands.”
 
Dietzman will lead eHealth Exchange's continued focus on expanding nationwide interoperability, advancing modern standards including HL7 FHIR, supporting TEFCA implementation, and fulfilling the organization's pledge to become a CMS-Aligned Network under the CMS Health Tech Ecosystem initiative.
