Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 94.2% of the total across 292 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 58 manufacturers, the largest accounting for just 8.3% — the pattern of someone who eats at a lot of different presentations. 2025 is the largest year on record at $2,694, 3.2 times the $838 reported in 2021. Among gerontology clinicians in CA with any reported payments, this total sits in the top 5% — high for the specialty, which is a reason to read the composition above rather than the number alone.
Across 292 payments — averaging $27.79 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.
How this compares
$8,113 in reported general payments places this provider in the 95th percentile of 348 gerontology providers in California.
