Chief Judge Allen also served as the cadre lead for the Hearing Office Chief Administrative Law Judge Supplemental Training, providing guidance, tools, and materials to assist supervisory judges to implement consistent and policy-compliant management of hearing offices.

In October 2018, Chief Judge Allen began his career with the HHS Office of Medicare Hearings and Appeals as an Associate Chief Judge in the Atlanta Field Office. He was instrumental in successfully standing up this new office and creating a fully functional judicial cadre.
