The NPI date is when this clinician registered for a National Provider Identifier, the billing number used on health claims. It is not a license, graduation or board-certification date. NPIs were first issued in May 2005 and became required on claims in 2007–2008, so an early date usually means the clinician was already in practice before then. What an NPI is

Education and training

  • 2008Medical school: University of Virginia School of Medicine
  • 2008Registered with an NPI (national billing number; not a license date) — NPIs began in 2005, so practice likely started earlier
