Payments from drug & device makers
What this record shows
This record is dominated by consulting fees: $22,898 of the $26,080 with a category attached, or 87.8%. Pfizer accounts for 74.3% of it on its own, with 2 other manufacturers making up the rest. Reporting peaked in 2022 at $8,400 and has fallen 99.7% since, to $25 in 2025. Among pediatric infectious diseases 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 20 payments — averaging $1304.00 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

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.
