Don Bosco Technical College (DBTC) in Mandaluyong is a pioneer of Salesian Schools in Metro Manila.
DBTC also temporarily transferred some of their primary level faculty to Don Bosco School Manila.

Faculty members who were temporarily transferred to DBS Manila were offered a choice as to their preferred employer.
