Payments from drug & device makers
What this record shows
The money is spread across several categories — travel and lodging (53.3%), food and beverage and consulting fees — rather than concentrated in one kind of arrangement. Coopervision Inc. accounts for 67.2% of it on its own, with 6 other manufacturers making up the rest. 2022 is the largest year on record at $1,808, 2.5 times the $721 reported in 2019. Among optometrist clinicians in MN with any reported payments, this total sits in the top 10% — high for the specialty, which is a reason to read the composition above rather than the number alone.
Across 18 payments — averaging $143.75 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

How this compares
$2,588 in reported general payments places this provider in the 90th percentile of 826 optometrist providers in Minnesota.
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.
