Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 95.2% of the total across 142 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 28 manufacturers, the largest accounting for just 21.8% — the pattern of someone who eats at a lot of different presentations. 2025 is the largest year on record at $2,091, more than ten times the $91 reported in 2021. Among physician assistant 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 142 payments — averaging $35.93 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

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.
