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

  • 1993Medical school: University of Colorado School of Medicine, Denver
  • 2006Registered with an NPI (national billing number; not a license date) — NPIs began in 2005, so practice likely started earlier

Undergraduate school, residency, fellowship, licensing exams and board certification aren’t in public federal data. Board certification can be confirmed with the certifying board (ABMS member boards for MDs, AOA boards for DOs).

Specialties and state licenses

  • Medical Oncology Physician primary
    MN license 45762

As reported to the NPI registry. To confirm a license is current, check the state medical board.

Medicare fee-for-service only. CMS leaves out services billed for fewer than 11 patients. These figures describe a practice’s Medicare work; they aren’t a measure of quality.

Medicare prescriptions

Prescriptions filled under Medicare Part D, including refills. CMS leaves out drugs prescribed fewer than 11 times.

Industry-funded research

Named as a principal investigator on 4 industry-funded studies in 2025, from 3 companies. The companies reported $58,511 in research payments for these studies, mostly to the institutions running them.

From CMS Open Payments research payments, where companies name up to five principal investigators per payment. Research payments usually go to hospitals, universities and research sites, not to the investigator personally. A payment is not evidence of wrongdoing.
