DAVID A. ZAK & ASSOCIATES, LLC specializes in providing expert vocational rehabilitation testimony and trial preparation services to federal agencies engaged in disability benefits adjudication and employment discrimination proceedings. The firm delivers highly specialized vocational expert witness support, including functional capacity evaluations, labor market analyses, and testimony development for Administrative Law Judge hearings and EEOC litigation. Their technical expertise centers on interpreting vocational data, assessing occupational requirements, and translating complex disability and employment barriers into legally defensible conclusions, ensuring agencies can substantiate benefit determinations or employment compliance decisions with credible, evidence-based expert analysis. A key differentiator is their focused application of vocational rehabilitation principles within formal legal and administrative frameworks, bridging clinical assessment with procedural rigor required in federal hearings. The contractor has established direct relationships with the Social Security Administration and the Equal Employment Opportunity Commission, delivering mission-critical vocational expertise to support appeals of denied benefits and employment discrimination claims. For SSA, they provide expert witnesses for ALJ hearings involving Social Security Disability Insurance and Supplemental Security Income appeals. For EEOC, they offer trial preparation and expert testimony in cases requiring vocational analysis of reasonable accommodation, disparate impact, and job function feasibility. These engagements reflect a pattern of trusted, repeat collaboration on high-stakes administrative and civil rights matters. The firm’s primary industry focus is NAICS 624310—Vocational Rehabilitation Services—where they operate at the intersection of disability policy, labor economics, and legal procedure. Their specialization lies in applying vocational assessment methodologies to federal adjudicative contexts, positioning them as a niche provider for agencies requiring authoritative, defensible vocational opinions in benefit and compliance proceedings. DAVID A. ZAK & ASSOCIATES, LLC is a small business structured as a 2J entity, headquartered in Pittsburgh, Pennsylvania. While no federal certifications are currently listed, the firm’s demonstrated expertise and direct agency engagements establish a credible footprint in the federal vocational services market.
