Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 100.0% of the total across 129 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 22 manufacturers, the largest accounting for just 23.4% — the pattern of someone who eats at a lot of different presentations. Reporting peaked in 2019 at $660 and has fallen 96.7% since, to $22 in 2025. That places this record below the midpoint for neurology clinicians in FL, where the typical reported total is $1,698.
Across 129 payments — averaging $16.59 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
