Chairman
Martin chaired Grichan Partnership from 2015-2021, and was a key contributor to the genesis of The Grichan Whitestone Partnership.
Bringing a level of senior management experience that is seldom found in the recruitment sector, having successfully led OCS, a company with 27,000 employees and £500m turnover, his strategic thinking, senior network and market knowledge – especially of managed services – have enabled GWP to “further distance itself from the recruitment herd” (as one candidate put it).
Away from the desk, Martin is a sports enthusiast and enjoys golf and walking which, he insists, are “not the same thing”.

Founding Partner
As the founder of The Grichan Partnership, Richard is the co-founding Partner of The Grichan Whitestone Partnership.
Richard leads on the Executive Search function.
Prior to founding The Grichan Whitestone Partnership, Richard was CEO at The Grichan Partnership, which he had founded in 2007, successfully building Grichan into a business that offered true partnership with all stakeholders focusing on “hard-to-fill” senior roles across adjoining Business Services/Outsourcing Sectors.
Joining forces with Rob effectively combines interim and executive recruitment businesses into what is now The Grichan Whitestone Partnership with a shared long-term service line of Business Consulting.
Richard lives in Worcestershire, with his wife, daughter, and cheeky Jack Russell cross. Outside of work, he’s a keen motorcyclist and passes on these skills through his charitable work with the motorcycle arm of the Institute of Advanced Motorists whilst training others to gain the advanced riding qualification.

Managing Partner
As the founder of The Whitestone Partnership, Rob is one of the co-founding Partners of The Grichan Whitestone Partnership.
Rob leads on the Interim Management and Business Consulting functions.
Prior to founding The Whitestone Partnership, Rob was a director at one of the UK’s leading Interim Service Providers, leading their Infrastructure, Business and Support Services practice and has featured in the IIM’s top 20 Consultants.
With a career spanning over 20 years, Rob’s skillset lies in developing strong relationships through his consultative, straight talking approach delivering solutions-focussed recruitment solutions.
With a stellar network of experienced executives, turnaround specialist and business consultants Rob has a genuine passion for the sector and is well placed to offer a full suite of executive recruitment solutions.
Rob lives in Yorkshire, with his wife, two children and Labrador. Outside of work, he’s a mediocre (at best) golfer, (very) occasional cyclist and is almost halfway through the Wainwright Mountains.
