Our Story

For over 30 years, our mission has stayed the same: to make world-class commercial training accessible and help professionals drive value in their organisations. Dr Carter wanted to make world-class commercial expertise accessible to everyone, from junior buyers to directors, across the public, private, and third sectors. Today, he leads the DPSS team in integrating cutting-edge technology, including AI and sustainable practices, into contract and commercial management to help organisations face the challenges of tomorrow.
