Bio

I build healthcare software.

I'm CTO at OneLine Health, where we're replacing the paperwork layer of medicine — patient intake, ambient listening, clinical documentation, EHR busywork. The stuff that eats half a doctor's day before they treat a single patient.

Before that, I co-founded Avhana Health with my brother Noah. We built clinical decision support tools that plugged into EHRs and scaled to tens of millions of patients across 150+ medical groups. Avhana was acquired by Amalgam Rx in 2021.

Earlier: building hospitals at Johns Hopkins, building missile launchers at Lockheed Martin.

On the side, I run Formstone Labs — a small studio where I build things I want to exist.

Based just outside New York. From Baltimore.
