Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 99.3% of the total across 81 separate payments, which is the pattern of a clinician who attends manufacturer presentations rather than one with a consulting arrangement. It is spread thinly across 32 manufacturers, the largest accounting for just 11.1% — the pattern of someone who eats at a lot of different presentations. Reporting peaked in 2022 at $422 and has fallen 65.0% since, to $148 in 2025. Among pediatrics clinicians in CA with any reported payments, this total sits in the top 10% — high for the specialty, which is a reason to read the composition above rather than the number alone.
Across 81 payments — averaging $19.61 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

General payments by program year
Who reported the general payments
Companies are grouped under their corporate parent — a single manufacturer often files under several CMS reporting entities. Research and ownership payments are counted separately and are not in this table.
What the payments were tied to
Products named in the reported payments. Only payments of $100 or more are attributed here — the typical reported payment nationally is a meal worth about $16, and listing those product-by-product would be noise.
- GARDASIL 9$114
How this compares
$1,589 in reported general payments places this provider in the 90th percentile of 5,539 pediatrics providers in California.
