Mary Mclarnon MD

Mary Mclarnon MD, a sole proprietorship medical consulting firm based in Mamaroneck, New York, provides independent medical case review services for disability adjudication to the Social Security Administration as a prime contractor under blanket purchase agreements, with no small business set-aside designation. The vendor operates exclusively with one federal customer and has maintained a continuous contracting relationship with the SSA since at least 2003, specializing in medical evidence evaluation supporting Social Security Disability Insurance and Supplemental Security Income determinations across SSA regions covering New York, New Jersey, and the Southwest (Dallas) region.

Dr. Mclarnon's customer concentration is complete — the Social Security Administration accounts for 28 of 29 recent awards and $11.9 million of $12.2 million combined potential value across the vendor's prime footprint. All work is firm fixed-price medical consulting categorized under NAICS Offices of Physicians (except Mental Health Specialists), with most awards rendered as Medical Consultation PSC codes. Recent call orders include a $251,805 SSA BPA call issued June 17, 2026, for 2,475 independent disability case reviews in the New York region through June 30, 2027; a $322,028 call for the Southwest Region (Dallas) awarded April 2, 2025, through June 30, 2026; and a $48,725 call awarded April 24, 2026, for case reviews through December 31, 2027.

The vendor sits on three SSA blanket purchase agreements — SS021140095 (10 task orders, $1.4 million combined potential value), 28321321AC0240012 (7 task orders, $1.7 million), and SS02164C015 (6 task orders, $963 thousand) — with the underlying BPA established January 4, 2021, carrying a total ceiling of $2,138,016. Award velocity is low and consistent: one award per year in 2022 through 2025, rising to two in 2026. Only $301 thousand in combined potential value faces ultimate completion within the next twenty-four months, indicating minimal recompete exposure in the near term. The vendor operates as a 100% prime with no subcontractor footprint.
