The Department of Veterans Affairs (VA) intends to negotiate a sole source contract with Dr. Linda S. Birnbaum for her expertise as Co-Chair of the Air Force Health Study Assets Transition Stakeholder Group. The contract, which will last for one year, aims to leverage Dr. Birnbaum's extensive background in toxicology and her experience with Vietnam-era Veteran health issues to set goals, plan meetings, and moderate symposia. This specialized consulting service is deemed essential, as no other entity possesses the necessary knowledge and expertise, making competitive solicitation unfeasible. Interested parties may contact the Contracting Officer, Ann Marie Stewart, at annmarie.stewart@va.gov for further inquiries, with the applicable NAICS code being 541690 and a size standard of $19 million.
