Who are we?

Mast People Support was set up in 2020 by Kate Marston. Kate is a former Detective Sergeant from the Metropolitan Police who went on to lead the investigations function at a FTSE 100 luxury brand.

Recognising the need for expert investigators who understood that people were at the heart of workplace issues, she decided to found Mast People Support and is on a mission to change the way workplace matters are dealt with. 


At Mast People Support, we know that our clients value the practical, reliable and flexible support that we provide.

We strive to make working with us easy, even if the scenario we are supporting you with isn't! 


My experience with Mast People Support and their investigation services exceeded my expectations in every aspect. Their expertise, impartiality, support, and commitment to simplicity truly made a difference. I wholeheartedly recommend Kate and her team to anyone needing a thorough and reliable investigation service. Their dedication to fulfilling their core values is evident, and their professionalism sets them apart.
