Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 100.0% of the total across 30 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 15 manufacturers, the largest accounting for just 20.6% — the pattern of someone who eats at a lot of different presentations. Reporting peaked in 2021 at $194 and has fallen 93.0% since, to $14 in 2025. That places this record below the midpoint for obstetrics & gynecology clinicians in TX, where the typical reported total is $863.
Across 30 payments — averaging $23.51 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
