Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 100.0% of the total across 279 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 33 manufacturers, the largest accounting for just 14.0% — the pattern of someone who eats at a lot of different presentations. Reporting peaked in 2021 at $1,247 and has fallen 68.7% since, to $391 in 2025. That places this record below the midpoint for allergy clinicians in TX, where the typical reported total is $5,140.
Across 279 payments — averaging $19.18 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

Paid to pharmacies, not to this prescriber.
Companies that both paid and supply prescribed drugs
These companies both reported payments to this provider and make drugs the provider prescribed under Medicare Part D in 2024. For most specialties this overlap is expected — a cardiologist who is paid by a cardiology drugmaker also treats heart disease. It is shown so the reader can see it, not because it implies anything on its own.
| Company | Paid to this provider | Part D cost of their drugs |
|---|---|---|
| GSKBreo Ellipta, Arnuity Ellipta | $575 | $7,06924 claims |
Reading this fairly. The Part D column is what drug plans and patients paid pharmacies — this provider received none of it, and it reflects how many patients they treat and what those drugs cost. Against peers, this provider's reported payments sit in the 50th percentile of 69 allergy providers in Texas.
