Abbott joins the agency from sister company Ashfield In2Focus, part of the CSMS division of United Drug.
Her recent roles include head of operations, head of resourcing and head of training.
Universal Procon global managing director Graham McIntosh said: "Denise has the expertise, analytical skills and client-centric approach that will strengthen our UK operations. As UK country manager she will be the lynchpin between the business development and the operations teams, ensuring a consistent and customer-focused service for our clients."
Abbott human resource experience would also prove "invaluable" as Universal Procon continues its recruitment drive, he added.
