Pearson-Myatt previously managed her own financial consultancy and before that previously held financial directorships at companies including Mueller Europe and Brassware Sales.
The appointment comes after DRP Group announced plans in October to recruit ten new members of staff following wins with corporates such as Office Depot.
Pearson-Myatt will be responsible for reviewing the firm's finance, health and safety and IT systems following the company's recent growth, which saw the addition of eight members of staff and an extra 929sqm of production space within the past year.
She said: "The business is doing very well and has been through a big period of growth, so it's part of my job to ensure that continues."
DRP Group managing director Dale Parmenter added: "Of the many candidates who applied for the role we felt April would bring a expert perspective to the financial and commercial aspects of the business. Taking on April in the current economic climate was a prudent step and she has already begun to improve the efficiency of our financial processes."
