I have had the good fortune to have collaborated with Thomas across decades and multiple engagement efforts. Simply put, he is among a select few in the health industry with a deep understanding of architecture, software, engineering, and health in such a way as to be able to provide real insight into interoperability and solutions to address those needs within this sector. Many practitioners are early adopters and effective technologists, but few have the vision and experience allowing them to be the pioneers into new solutions, methods, and approaches necessary to realize the potential of interoperable health systems. Thomas is one of those pioneers. Dating back approximately two decades, Thomas' work on multi-level modeling exposed the importance of knowledge-engineering as a complementary construct to data interoperability, proving much-needed clinical context to data making it become information and high-value at a point-of-care. These ideas continue today in what is still leading work within HL7, such as the Clinical Information Modeling Initiative (CIMI), a forbear group identifying and working to close gaps in the emergent FHIR standard. Within the OpenEHR community, Thomas has long been a technical leader, serving as the chief architect of many of those specifications, and the convenor of many activities associated with this open specification effort, and ultimately open source implementations of a broadly accepted EHR platform effort. To this day, I continue to seek out Thomas for his opinions on industry challenges, emerging approaches and technologies, and recommendations on how to advance several aspects of interoperability within and beyond the standards community. His diversity of experience, professionalism, and involvement in quite literally dozens of regional and national e-health activities the world over gives him a perspective that is nearly impossible to duplicate. He has an innate ability to see beyond existing solutions to the "art of the possible," fueled by insight and matured by hard knocks and years of work in the trenches. Thomas is an immediate difference maker to any team of which he is a part, and to any organization with the foresight to engage him.

Thomas is the consumate software engineer. Always looking for perfection in design but with an eye of pragmatism.
