International school of London
Through various different projects over the last 14 years, from operations to strategic planning, Derrick has been of fundamental value to me and the schools I have supported. Most recently, we have collaborated on a project to create tender documents to best support schools covering two continents. If you are looking to work with a strategic and procurement consultant who will treat the project as if it were their own, while also lending the perspective and insights of an outside expert, I will without a doubt recommend Derrick!
St John’s College, Southsea
I would highly recommend Derrick for advice and support around the negotiation of IT and photocopy contracts. He has significant knowledge and experience in negotiating contracts. He was able to save us several thousand pounds. He works quickly and professionally to achieve the most favourable terms for his clients.
Moulsford Prep School
From the start, Derrick demonstrated his expertise and made the process simple for us. He began with a thorough audit of our copier setup and then created a detailed technical specification. His guidance during the tender process allowed us to make informed decisions, and his professionalism ensured everything went smoothly.
