The Diagnostician

American Healthcare Is Sick, Misdiagnosed, and Getting Worse; It's Time to Call the Doctor.

A physician and career CMIO applies medicine's oldest tool, the diagnostic method, to American healthcare itself. Seventeen chapters take the history, read the evidence, commit to a working diagnosis, and write the treatment plan an industry has been refilling without one.

Physician executive leadership for all the systems that support healthcare.

I bring the physician's clinical method to health systems: take the history, examine the work, read the data honestly, commit to a written diagnosis, then treat and follow up. When the seat is empty, I can hold it.
