MASO, on behalf of USARPAC, is conducting a Sources Sought Notice to identify potential sources for Athletic Trainer (AT) support services as a follow-on requirement. The contractor would provide 18 full-time equivalent certified Athletic Trainers and 6 Lead Athletic Trainers who meet DoD and DHA credentialing standards. Services would be embedded at military installations in Korea (Combat Aviation Brigade/2d Infantry Division, 210th Field Artillery Brigade, Camp Carroll, Camp Humphreys, and Osan Air Base) and Guam. The anticipated performance period is 12 May 2027 through 11 May 2028, with four option years, and the PWS is attached. Responses are for planning purposes only and should include company identifying/socioeconomic information and a capability statement limited to ten pages, with questions or comments submitted to the listed POC; the Government may use responses to shape its acquisition strategy, including possible sole-source award if competition cannot be verified.
