Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 100.0% of the total across 214 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 12.7% — the pattern of someone who eats at a lot of different presentations. 2025 is the largest year on record at $4,466, more than ten times the $68 reported in 2022. Among psychiatric/mental health 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 214 payments — averaging $22.35 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

How this compares
$4,783 in reported general payments places this provider in the 90th percentile of 2,433 psychiatric/mental health 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.
