Our Story

At FHIRBlocks, we have a big vision—that every person should have control over their health data; who they share it with, what they share, how long, for what purpose,...  We’re passionate that it’s now truly possible to empower healthcare consumers and deliver differentiated business value to organizations while transforming healthcare through cloud, decentralized identity, mobile wallets, blockchain and other technologies.  This is how our vision came to be…


With the BellSouth merger that re-created the new AT&T in 2006, it’s chief strategist Doug Bulleit, left to pursue a Consumer Directed Health Care (CDHP)-enabling concept that he had been leading there.  It was a vision that was stimulated by frustration over his father’s avoidable death, and one that Doug shared with other executives agreeing to fund the launch of DCS Health.  But the new company introduced its Health-Over-IP (HoIP) portal in the worst possible times: e.g., the recession then settling in, coupled with positive reassertion of a wider Federal government role in its citizens’ health, ultimately resulted in the DCS dream being put on hold (but, ironically, planting the seeds of its reemergence as FHIRBlocks nearly a decade later).


Undaunted by HoIP’s temporary suspension, Mr. Bulleit busied himself as an advisor to an assortment of early-stage companies. By and by, he became immersed in blockchain development and eventually found himself delivering a lecture series on enterprise blockchain applications at The Georgia Institute of Technology. While there, Dr. Mark Braunstein (GaTech’s Professor of Healthcare Informatics) approached him with a question: “Can a distributed ledger (aka, a permissioned blockchain) solve FHIR’s* trust problem?”


A little bit of digging revealed that “FHIR’s trust problem” is rooted in the simple fact that the owners of sensitive patient information—patients—typically have little control, sometimes not even access, to it! Soon thereafter, over a lunch on the back of the proverbial napkin, and out of the realization that decentralized identities and associated verifiable credentials promise a near-perfect solution, FHIRBlocks was born in late 2016. 


FHIRBlocks then shifted to Durham NC where the CIO and CTO of the prestigious Duke University Health System (DUHS) instantly saw its promise and embarked upon a multi-year series of proof-of-concept trials.


Toward the end of 2020 and in the midst of the COVID epidemic, DUHS leadership suggested that FHIRBlocks core credentials, consent & compliance management-as-a-service would be more naturally deployed as a cloud-based solution in Azure.  Microsoft also instantly saw the promise; and the rest is, as they say, soon-to-be history. 


T.S. Eliot once wrote… 


 “And at the end of all our exploring, will be to arrive at where we started. And to know that place for the first time.”


It’s strange how, sometimes, the paths of our lives come full circle to better outcomes than we could have imagined along the way. The Obama Administration’s American Recovery & Reinvestment Act tactic—by heavily subsidizing the conversion of paper-based heath records to modern electronic alternatives—led to the FHIR API. And who could have guessed that Mr Bulleit’s wide range of experience and, perhaps more importantly, his Rolodex of superior relevant talent, would lead to the FHIRBlocks solution. 


Together with Microsoft’s cloud market leadership and health technology innovations, FHIRBlocks is poised to address one of the healthcare world’s nagging pains: how to “solve FHIR’s trust problem” and to finally give people the control they need to make life better and free cost-saving liquid data out of the siloes of electronic health records that still dot the countryside here and abroad.


If you are passionate about the need for person-centric healthcare, and interested in the power of technology to transform, come join us in our quest!
