Payments from drug & device makers
What this record shows
The money is spread across several categories — consulting fees (55.6%), speaking fees and travel and lodging — rather than concentrated in one kind of arrangement. 10 manufacturers reported payments, led by Argenx US, Inc. at 52.7% of the total. 2025 is the largest year on record at $80,278, 3.8 times the $21,038 reported in 2019. Among neurology clinicians in UT with any reported payments, this total sits in the top 5% — high for the specialty, which is a reason to read the composition above rather than the number alone.
Across 183 payments — averaging $1449.65 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

- Grifols USA, LLC$78K
- Takeda Pharmaceuticals U.S.A., Inc.$17K
- Tanabe Pharma America, Inc.$13K

Across 59 payments — averaging $11,300 each. Payments tied to a research study. These frequently flow through the physician to a hospital or research institution rather than to the physician personally.

What the payments were tied to
Products named in the reported payments. Only payments of $100 or more are attributed here — the typical reported payment nationally is a meal worth about $16, and listing those product-by-product would be noise.

How this compares
$265,286 in reported general payments places this provider in the 95th percentile of 157 neurology providers in Utah.
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.
