The founder
Frontier medicine
is my field.
I founded Xavtli to turn the demands of medicine at the edge into the technology that moves it forward.
At Brooke Army Medical Center, I built the interventional trauma program, integrating image-guided and endovascular care. I led the interventional radiology service, directed interventional oncology and served as Consultant to the Air Force Surgeon General for Interventional Radiology Services. That experience shapes how I approach invention: understand the procedure, the clinician and the conditions in which both have to work.
My published work spans expeditionary endovascular trauma care, AI-assisted ultrasound in austere environments and procedural autonomy for human spaceflight. These are the questions driving frontier medicine: how to extend expertise, make intervention possible with fewer resources and deliver care when evacuation is out of reach.
Early work in drainage-catheter design sharpened my understanding of the gap between what a procedure demands and what the available tools can deliver. I built Xavtli around the larger challenge: bringing clinical expertise, medical devices, intelligence and care systems together to close that gap.
The company
Medicine for the Edge.
Xavtli develops frontier health solutions from a physician’s understanding of what care demands. We design for precise intervention, less invasive treatment, recovery and continuity, with the realities of the clinical environment built into the work.
Through Farstep and Xovli, that purpose spans frontier intervention and environmental and occupational health. Devices, intelligence and care delivery advance together.
Our ambition reaches from expeditionary care to augmented and robotic medicine. The needs of people on Earth drive the work. Procedural autonomy beyond Earth extends the horizon.

Expertise built
through practice.
Board certified in interventional and diagnostic radiology.
A distinguished graduate of the United States Air Force Academy, John earned his medical degree at Georgetown, completed his residency at Walter Reed / National Capital Consortium, where he served as chief resident, and completed fellowship training in vascular and interventional radiology at MedStar Georgetown.
He also served as an Associate Professor at the Uniformed Services University, teaching and mentoring clinicians in procedural care and research.
