What do certification dates mean?
A doctor is “first certified” on the date when they first become board certified in their area of medical expertise (medical specialty).
The “most recent certification” date is the last time a doctor completed requirements including education, training, and passing an exam, in their area of medical expertise; the most recent and first certified dates may be the same.
A doctor’s information on Certification Matters is updated from time to time with data sent by their certifying board (ABMS Member Board) and may not reflect very recent changes to their certification.
