How I Can Help

I help agencies, foundations, and research organizations navigate complex disability policy questions, design rigorous evaluations, and turn evidence into strategy. These are the areas where clients tend to rely on me most.

Wittenburg Consulting LLC is active in SAM.gov and available for prime, subcontractor, and senior advisory roles on federal evaluation, technical assistance, and policy research opportunities.

Grant & Contract Proposal Writing

I help research teams build winning proposals for federal grants and contracts. I have led or co-led proposals for awards up to $30 million across SSA, DOL, HHS, RSA, NIDILRR, and foundation funders, and know what review panels are looking for.

Program Evaluation Design

I design and oversee rigorous evaluations, including randomized trials, quasi-experimental studies, and mixed-methods designs, grounded in decades of directing some of the nation's largest federal disability demonstrations, including POD, BOND, and Ticket to Work.

Policy Analysis & Dissemination

I translate complex disability and human services evidence into clear recommendations through policy briefs, technical assistance to state agencies, testimony preparation, and keynote presentations that reach decision-makers and front-line practitioners.

Organizational Strategy & Advisory

Drawing on VP-level leadership at Westat and two decades at Mathematica, I advise research organizations on portfolio management, business development, restructuring, and positioning in the federal evaluation marketplace.

Federal Demonstrations & Systems Change

I have directed large-scale demonstrations for SSA, DOL, and HHS that test new approaches to disability benefits, employment services, and youth transition. I bring that implementation knowledge to new projects from day one.

Youth Transition & Foster Care

I focus on transition-age youth policy, including youth with disabilities, child SSI recipients, and foster care populations, bringing research, evaluation, and program design expertise to improve employment and life outcomes.

David C. Wittenburg, Ph.D.

For more than 25 years, I have worked to improve employment and independent living outcomes for people with disabilities through research, policy, and evaluation. My career has included leadership roles at Mathematica, where I served as Disability Area Director and Senior Fellow, and Westat, where I was Vice President overseeing the Social Policy & Economics Research practice, as well as earlier positions at the Urban Institute and the Lewin Group. Across these roles, I have worked at the intersection of disability policy, program evaluation, and human services.

I have directed some of the nation's largest federal disability demonstrations, including the Promoting Opportunity Demonstration, the Benefit Offset National Demonstration, and the Ticket to Work evaluation, and led multidisciplinary teams of more than 100 staff. My research has been published in the Journal of Public Economics, Medical Care, Social Service Review, and dozens of other peer-reviewed outlets.

I have testified before the U.S. House Ways & Means Committee on SSI benefits for children, served on two National Academies of Sciences panels, and received a New Jersey Changemaker Award for community leadership as Board Co-Chair of CASA Mercer-Burlington County.
