Payments from drug & device makers
What this record shows
The money is spread across several categories — speaking fees (56.2%), consulting fees and food and beverage — rather than concentrated in one kind of arrangement. 6 manufacturers reported payments, led by Pfizer at 56.2% of the total. Reporting peaked in 2022 at $6,099 and has fallen 96.8% since, to $193 in 2025. Among internal medicine clinicians in CO 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 24 payments — averaging $717.50 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

General payments by program year
Who reported the general payments

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
$17,220 in reported general payments places this provider in the 95th percentile of 1,430 internal medicine providers in Colorado.
