WHY ELLIS CLINIC?

Experience Is More Than a Number.

In a difficult disability case, the medical question is rarely just “What is the diagnosis?” The harder question is what the medical evidence means—and how clearly the physician can explain it.

A Practice Built Around Difficult Medical Questions

John W. Ellis, M.D. has spent decades working at the intersection of medicine, occupational injury, disability, impairment, and medical causation.

Ellis Clinic's work is centered on careful record review, examination, chronology, objective findings, medical reasoning, and a clear explanation of how the evidence supports—or does not support—a conclusion.
