Payments from drug & device makers
What this record shows
This record is dominated by food and beverage: $2,027 of the $2,323 with a category attached, or 87.3%. It is spread thinly across 22 manufacturers, the largest accounting for just 23.0% — the pattern of someone who eats at a lot of different presentations. Reporting peaked in 2019 at $789 and has fallen 75.0% since, to $198 in 2025. That places this record below the midpoint for procedural dermatology clinicians in CA, where the typical reported total is $2,566.
Across 95 payments — averaging $24.46 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

How this compares
$2,323 in reported general payments places this provider in the 45th percentile of 108 procedural dermatology providers in California.
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.
