Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 100.0% of the total across 83 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 25 manufacturers, the largest accounting for just 22.4% — the pattern of someone who eats at a lot of different presentations. Reporting peaked in 2023 at $739 and has fallen 65.0% since, to $259 in 2025.
Across 83 payments — averaging $23.21 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

How this compares
$1,926 in reported general payments places this provider in the 75th percentile of 705 obstetrics & gynecology providers in Colorado.
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.
Most prescribed under Part D
| Drug | Claims | Cost to plans & patients |
|---|---|---|
| Estradiol | 19 | $886 |
| ProgesteroneProgesterone, Micronized | 12 | $412 |
