In this role, he is responsible for planning, soliciting, awarding, and administering contracts essential to the daily operational sustainability of the facility. His procurement activities center on securing high-volume food and beverage supplies to support the nutritional needs of the incarcerated population, ensuring compliance with federal dietary standards and logistical reliability.
