The Medical Expert Witness Starter Kit

Everything you need to decide whether expert work fits your practice, and to start it credibly: qualification checklist, fee worksheet, CV guide, and your first deposition.

No separate certification is required, despite what course sellers imply. If you check these boxes, attorneys can retain you today.

Board certification
In the specialty you'll opine on, many state statutes require it when the defendant is certified.
✓
5+ years clinical experience
Courts and juries credit physicians who actively treat what they testify about.
✓
Active practice
