Unified Radiology, Built by People Who Know It
Sirona is built by leaders who have spent decades designing, deploying, and supporting clinical imaging and reporting systems. We focus on infrastructure that works in the real world — reliably, securely, and at scale.
About Us
Sirona was founded in 2018 with a clear purpose: to simplify radiology workflow and infrastructure so clinicians can focus on what matters most — patient care. Our team doesn’t think about technology in isolation; we think about how radiology works in practice.
Our platform unifies imaging, reporting, dictation, and workflow in a single cloud-native system. This eliminates the fragmentation and complexity that have long defined legacy radiology stacks. This approach was shaped by years of deep domain experience with clinical reporting systems and what works — and doesn’t — for radiologists in daily practice.

Experience You Can Trust
Our platform is built by people who have spent decades operating, building, and refining imaging and reporting systems across clinical environments. Sirona’s leadership has deep roots in radiology infrastructure and healthcare technology. Before founding Sirona, our leaders were at the forefront of building the systems radiologists use every day — from imaging tools to reporting workflows.
Under the guidance of Ken Kaufman, CEO, Sirona’s foundation is rooted in real-world experience:
“Radiology doesn’t need more complexity. It needs infrastructure that disappears into the background.”
