Derek J. O'Brien, M.D., P.C., a for-profit medical consulting firm based in Atlanta, Georgia, provides independent medical case reviews and psychiatric consultation services to the Social Security Administration as a prime contractor under multiple blanket purchase agreements, with no set-aside designations across its federal work.

The vendor operates exclusively as a prime contractor (100% of awards) and serves a single customer agency. The Social Security Administration accounts for all 35 awards in the source data, representing $7.1 million in combined potential value. Derek J. O'Brien, M.D., P.C. specializes in disability adjudication support work, conducting independent medical reviews of disability claim case files to support SSA's Atlanta regional office operations and broader disability program evaluation processes. Recent representative work includes a $238,600 BPA call from SSA awarded June 3, 2026, for independent medical case reviews running through June 30, 2027; a $252,356 call order from February 2025 for disability case reviews at the Atlanta regional office; and a $200,424 call order from February 2024 for 1,800 independent case reviews in support of SSA Region 4 operations. The vendor's work is classified under NAICS offices of physicians (both mental health specialists and general), with the PSC category dominated by medical-psychiatric consultation codes.

The vendor holds seats on three SSA blanket purchase agreements: BPA SS041040088 (16 task orders, $421 thousand combined potential value), BPA SS04164C005 (9 task orders, $537 thousand combined potential value), and BPA 28321321AC0440026 (7 task orders, $1.2 million combined potential value).

Only one award carries an ultimate completion date within the next twenty-four months (combined potential value $239 thousand), representing limited near-term recompete exposure. Of the $7.1 million combined potential value across all awards, $2.1 million has been obligated to date (30% of potential value), indicating ongoing work performance against the contracted ceiling values.
