Tomak Sheri L

Tomak Sheri L, a woman-owned small business sole proprietorship based in Prosper, Texas, provides medical consultant services for disability claim reviews to the Social Security Administration as a prime contractor (100% of recent awards), operating exclusively under SSA's regional medical consultant blanket purchase agreements with no subcontract exposure.

The vendor's entire federal footprint centers on SSA's disability determination program. Tomak Sheri L holds three active BPA vehicles with SSA: a $2.01 million multiple-award BPA for Region 8 (Denver) medical consultant services running through February 2029; a $1.33 million single-award BPA for Region 5 (Chicago) services running through January 2028; and a $1.78 million single-award BPA for Dallas-area services that was terminated in September 2023. Work consists of firm fixed-price independent case reviews of disability claim case files, non-case hours, and medical opinions to support SSA's disability benefits determinations. Recent named work includes a $235.2 thousand call order from July 2025 for independent case reviews in the Midwest/West region, a $61.7 thousand call order from April 2026 for similar reviews in the Chicago region, and a $56.7 thousand call order from July 2024 for 550 independent case reviews in Region 8. All work is performed at the contractor's Prosper, Texas location.

Customer concentration is absolute: the Social Security Administration represents 100% of awards (41 total) and 100% of combined potential value ($9.7 million). The vendor operates under no set-aside designation across its prime footprint, competing full-and-open. Category concentration reflects SSA's medical review focus: 24 awards fall under NAICS Offices of Physicians (except Mental Health Specialists), 17 under Offices of Physicians, Mental Health Specialists; 29 awards carry PSC Medical- Medical/Psychiatric Consultation, seven PSC Behavioral And Mental Health.

Activity has declined sharply in recent years. The vendor recorded four awards in 2022, six in 2023, five in 2024, one in 2025, and one in 2026, suggesting potential recompete or consolidation pressure on SSA's regional medical contractor program. Of $9.7 million in combined potential value, $2.5 million (25%) has been obligated; the remaining exposure sits in the active BPA vehicles. The vendor competes as a sole proprietor with no recorded subcontract relationships or multi-vendor partnerships, making capability limited to individual medical consultant services rather than scaled team delivery.
