Board Service
A physician director who asks the pressure-testing question on quality, safety, AI, and strategy, then leaves operations to management.
Board profilePhysician Executive · Board Director · Clinical AI
Technology doesn’t transform care. Leaders who redesign the work do.
I bring the clinical front line into the boardroom: 14 years of hospital medicine leadership, health system trustee service, and hands-on experience moving clinical AI from a measured pilot to enterprise scale.

Where I create value
Four ways I help organizations lead through change.
Every engagement starts with the same question: what does good look like, and how will we know we got there?
Fractional CMO & Executive Advisory
Part-time medical leadership with defined monthly hours: clinical strategy, physician engagement, quality, and multi-state compliance.
Engagement modelsClinical AI Adoption
Structured pilots with measures agreed before go-live, so AI decisions rest on evidence instead of demos.
The playbookHealth Tech Advisory
Clinical workflow and go-to-market input for AI and digital health companies, from a physician who has shaped products at Doximity and QuickBlox.
Advisory rolesThe pilot-to-enterprise playbook
Most AI pilots fail quietly. This one was built to answer a question.
When a large management company in emergency medicine and hospital medicine asked whether an ambient AI scribe could hold up on the wards, the goal wasn’t to prove the software worked. It was to find out what had to change around it.
Read the case studyDefine what good looks like
Quality and workload measures agreed before go-live, not after.
Measure before and after
A multidomain documentation-quality scorecard and adapted NASA-TLX physician workload surveys.
Redesign the workflow
Prompt optimization and template standards produced the largest quality gains.
Standardize, then scale
A physician voting committee set enterprise rules, and the company moved to enterprise scaling.
What the pilot taught us
“The gains didn’t come from the software alone. They came from redesigning the work around it.”
Board perspective
The questions boards face now are clinical questions.
How do we adopt AI responsibly? How do we protect quality and safety as margins tighten? How do we keep physicians engaged through change? I’ve worked through each one at the bedside, in committee, and as a trustee.
