No general payments reported
No drug or device maker reported general payments to this provider for 2019–2025. That is a common and unremarkable result.
Across 5 payments — averaging $37,283 each. Payments tied to a research study. These frequently flow through the physician to a hospital or research institution rather than to the physician personally.

How this compares
Too few public health & general preventive medicine providers in Nevadato place this figure against a meaningful peer group, so we don't.
Medicare billing
What this is not: this is the amount Original Medicare Part B allowed for services this provider billed in 2024. It is not their income. It excludes Medicare Advantage — now more than half of all Medicare enrollment — along with Medicaid and all commercial insurance, and it is gross practice revenue before staff, rent, supplies and malpractice premiums. CMS also suppresses any figure covering ten or fewer patients, so low-volume providers appear smaller than they are.
