Mandel Training Centre is a training and conferencing and accommodation facility place in Marlborough, Harare, owned and run by Delta Corporation. It was established by Delta in the late seventies to spearhead Management and Supervisory Development in the Delta Group. Mandel Training Centre opened its business to non-Delta companies both in the Private and Public Sectors in later years and is now generally considered one of the leading centres for Human Capability Development in Zimbabwe. Even though open to non-Delta business, Delta remains the center's anchor client.
