Nathaniel Michael Robbins

Nathaniel Michael Robbins, a sole proprietorship based in Norwich, Vermont, provides specialized medical expert and expert witness services to federal agencies as a prime contractor under two distinct customer programs. Robbins competes across both total small business set-asides and full-and-open awards, with roughly two-thirds of his contract volume designated as total small business set-asides on the HHS side and no set-aside designation on his Department of Justice work.

Robbins' federal footprint is anchored by medical case review and expert analysis for the Vaccine Injury Compensation Program (VICP) administered by the Department of Health and Human Services' Health Resources and Services Administration (HRSA). He holds a single-award Blanket Purchase Agreement (75R60222A00008) valued at $249,999 running through February 2027, against which HRSA has issued 23 task orders totaling $220,000 in combined potential value since February 2022. Under this BPA, Robbins conducts independent medical evaluations and case reviews to support HRSA determinations of eligibility and compensation for vaccine injury claims. Representative task orders include a $24,375 call (March 2026) supporting VICP and the Countermeasures Injury Compensation Program, a $24,750 call (April 2025) for vaccine injury case review, and a $22,500 call (June 2024) for case evaluation. He also provides expert witness services to the Department of Justice Civil Division on litigation matters, with 11 awards totaling $168,000 in combined potential value, including a $43,125 time-and-materials purchase order (March 2025) and a $32,201.79 purchase order (August 2022) for expert witness support.

Customer concentration is absolute and bifurcated: HRSA accounts for 24 awards ($470,000 combined potential value) and the DOJ Civil Division accounts for 11 awards ($168,000 combined potential value), comprising 100% of awards by both count and dollar value. Activity has contracted year over year — 11 awards in 2022, declining to one award in 2026 — with five awards totaling $115,000 in combined potential value reaching completion within the next twenty-four months and therefore facing recompete risk. Robbins' work is classified under two primary NAICS codes: Administrative Management and General Management Consulting Services (24 awards) and Offices of Physicians except Mental Health Specialists (9 awards), with all 35 awards registered under PSC code Support-Professional: Expert Witness. Robbins operates exclusively as a prime contractor with no subcontract footprint.
