Integrity, Commitment, Quality and Endeavour

"As a software developer working in financial services looking for a role outside the sector... Oliver took this vague request and ran with it, producing specs for roles.... that were exactly what I was looking for... Oliver's and Client Server's cross-sector networks made this move possible, and it's a very unique aspect to their offering."

Stephen - Senior Developer


"Nick (and Client Server in general) are quite different from other recruiters I have dealt with. He takes the time to understand where you are and what you want next so that he can find the right job rather than just any job. The communication throughout the process was perfectly pitched and I'm very happy with the end result."

Julian - Senior Developer​


"I have worked with Client Server before to my satisfaction. They provide a very professional approach, excellent communication and an overall exceptional service in recruitment... David represents those values extremely well... I had no questions unanswered. He has organised the process with flawless precision. I would always recommend him."

Marton - Head of Development​
