Christopher A. Callihan

Christopher A Callihan serves as a Contracting Officer, responsible for managing the acquisition process and ensuring the effective procurement of goods and services to support the agency's mission. In this role, he oversees the lifecycle of contracts, from solicitation and evaluation to award and administration, ensuring compliance with federal acquisition regulations. Regarding set-aside preferences, the procurement patterns show a primary reliance on full and open competitions, with no set-aside requirements accounting for the majority of actions. However, there is a notable commitment to socioeconomic goals, particularly through Service-Disabled Veteran-Owned Small Business (SDVOSB) set-asides, which represent a significant portion of the contracting activity, followed by general small business set-asides and occasional sole-source requirements. His procurement activity is heavily concentrated in the medical and scientific instrumentation sector. The primary focus areas include the manufacturing of analytical laboratory instruments and electromedical and electrotherapeutic apparatus. Additionally, his technical domain expertise extends to the procurement of surgical appliances and supplies, as well as optical instruments and lenses, with some activity in home health care services.
