JOHN W MCKINNEY III

John W. McKinney III specializes in providing expert vocational rehabilitation testimony as a witness in administrative hearings before Administrative Law Judges for the Social Security Administration. His core capability centers on delivering authoritative, evidence-based assessments of claimants’ functional capacities, work limitations, and vocational readiness in appeals involving Social Security Disability Insurance and Supplemental Security Income claims. He brings deep familiarity with SSA’s disability evaluation frameworks, including the Medical-Vocational Guidelines and the Social Security Rulings governing residual functional capacity determinations. His technical expertise lies in interpreting medical records, applying vocational labor market data, and translating clinical findings into legally defensible testimony that supports fair adjudication of benefit denials. His unique value lies in his precision in aligning vocational conclusions with SSA’s regulatory standards, ensuring hearings are informed by credible, compliant expert analysis. The contractor’s primary and only known federal relationship is with the Social Security Administration, where he supports the agency’s appeals process by serving as a vocational expert witness during hearing proceedings. This engagement reflects a highly specialized, mission-critical role in ensuring due process and regulatory consistency in disability determinations. His industry focus is narrowly defined by NAICS 624310, which encompasses vocational rehabilitation services—specifically, the provision of expert consultation and testimony in government disability adjudication contexts. This positions him as a niche provider within the federal disability ecosystem, serving a critical function in the administrative justice pipeline rather than offering broad rehabilitation programming. John W. McKinney III operates as a sole proprietorship under entity structure 2J, with no federal certifications on record. Based in Huntsville, Alabama, his market presence is focused exclusively on supporting federal administrative hearings, with no indication of broader geographic or institutional reach beyond SSA’s national appeals system.
