With the reorganization of the Department following the implementation of its Rationalization Plan, he was given the Assistant Regional Director for Management Services post in the same region in 2015 which paved the way for his Chairmanship of the Human Resource Merit, Promotion and Selection Board (HRMPSB) and the Regional Bids and Awards Committee (RBAC), among others.
