Preston Davis

Preston Davis, a minority-owned and Asian-Pacific American-owned sole proprietorship based in Webster, New York, provides independent medical reviews of Social Security Administration disability claim case files as a prime contractor exclusively under the SSA's regional blanket purchase agreements. The firm competes in full-and-open procurements without set-aside designation and has been registered in SAM.gov since 2006.

Preston Davis operates entirely within the Social Security Administration's disability adjudication program. All 43 recent awards are prime BPA call orders placed against SSA medical consultant IDIQs covering Regions 8 (Denver) and 9 (San Francisco). The firm holds three underlying multiple- and single-award blanket purchase agreements with the SSA: a $2.01 million multiple-award BPA covering Regions 8 and 9 (effective through February 28, 2029), a $2.67 million single-award BPA for Region 9, and a $1.81 million single-award BPA for Region 8. Work consists of independent medical case reviews in which Preston Davis medical professionals evaluate disability claim documentation, assess medical evidence, and provide expert determinations to support SSA's disability benefits adjudication. Recent call orders include a $143,424 ceiling from July 1, 2026 (performance through June 30, 2027), a $16,740 call from April 1, 2026, and a $46,800 call from July 1, 2024. Performance occurs at Webster, New York, with field work in Denver and San Francisco.

Customer concentration is absolute: the Social Security Administration accounts for 98% of awards (42 of 43) and 95% of combined potential value ($10.9 million of $11.4 million). Activity has remained flat to modest over the past five years — two awards in 2022, two in 2023, three in 2024, one in 2025, and two in 2026 — reflecting steady task-order issuance against mature IDIQs rather than growth trajectory. Only one award (combined potential value $143 thousand) reaches ultimate completion in the next twenty-four months, resulting in minimal recompete cliff exposure. Preston Davis places zero subcontract work and holds no positions on government-wide vehicles, IDIQs beyond the SSA regional BPAs, or other parent contracts.

The primary vehicle footprint is the five SSA regional medical consultant BPAs. The largest two — SS091140008 and SS09164C015 — carry fourteen and six task orders respectively, with combined potential values of $1.6 million and $1.9 million. Three additional single-award regional BPAs (28321324AC0840021, 28321321AC0940017, and 28321320AC0840012) support five, four, and three task orders respectively. Work is classified under NAICS 621111 (Offices of Physicians, Mental Health Specialists) and PSC Medical—Medical/Psychiatric Consultation, reflecting the firm's narrow but established role in SSA's regional disability review operations.
