About the company
Colb MD, A Mark, a sole proprietorship based in Boston, Massachusetts, provides independent medical case reviews for the Social Security Administration's disability adjudication program as a prime contractor exclusively under blanket purchase agreements, competing on full-and-open terms with no set-aside designations.
The vendor operates entirely within a single customer relationship. All 21 awards in the source record are SSA task orders; the combined potential value is $3.3 million, with $1.1 million obligated (34% of potential value). The vendor holds three active SSA Regional Medical Consultants (RMC) BPAs: a $2.148 million single-award BPA for Region 1 Boston area mental medicine case reviews (awarded August 1, 2024, running through March 31, 2029); Blanket Purchase Agreement 28321319AC0040001, from which six task orders carry $492 thousand combined potential value; and Blanket Purchase Agreement SS01154C002, from which eight task orders carry $461 thousand combined potential value. Recent representative work includes a $60.9 thousand firm fixed-price call from SSA dated June 18, 2026 (the vendor's most recent award), for 625 independent disability claim case file reviews with completion scheduled for June 30, 2027; a $56.9 thousand call from April 1, 2025 for independent case reviews under the mental medicine contract; and an $82.1 thousand call from April 1, 2023 for regional medical consultant services in Region 1.
The vendor specializes in offices of physicians (NAICS 621111) within the medical consultation services space, with 16 awards coded to medical-psychiatric consultation (PSC), 3 to physical medicine and rehabilitation, and 2 to other medical services. Award frequency has been sporadic—one award per year in 2022 and 2023, three in 2024, one in 2025, and two in 2026—reflecting task-order issuance patterns against stable BPAs rather than sustained growth trajectory. Only one award, valued at $61 thousand, reaches ultimate completion within the next twenty-four months and therefore faces recompete risk in that window. The vendor holds no subcontract or grant positions and does not sit on government-wide vehicles; all work flows through SSA regional medical consultant BPAs for disability evaluation support in the New England region.
