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 3 industry-funded studies in 2025, from 2 companies. The companies reported $266,203 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.
