About Us

TalentSource is the dedicated flexible resourcing department within CROMSOURCE, a high quality ISO-certified international provider of outsourced services to the pharmaceutical, biotechnology and medical device industries.

Corporate Overview

Since 1997 CROMSOURCE has been supporting pharmaceutical, biotechnology and medical device clients with outstanding clinical research and flexible resourcing solutions (through the TalentSource brand). At CROMSOURCE, we have vast experience with both large and small companies and have led many different approaches. The successful growth of CROMSOURCE has been achieved by putting high quality and client focus at the heart of everything we do.

CROMSOURCE, a privately owned, full service CRO, has two major complementary businesses: Flexible Resourcing (TalentSource Department) and Full-Service Outsourcing . By Acquiring MSOURCE in 2011, (headquartered in Belgium, which led to a change in name, so CROM became CROMSOURCE) the company not only strengthened its position in terms of expansion of infrastructure and capacity, but also added new services – Staffing Solutions – to the portfolio. Now CROMSOURCE continues to lead the way in providing flexible resourcing solutions.

We now offer a comprehensive portfolio of services, taking a flexible approach to ensure CROMSOURCE optimally supports the unique needs of each client. This could mean providing regulatory consultancy to a small company at the early stage of a medical device development programme, through to provision of full services to a pharmaceutical company performing a large global study to support registration of their product. Whatever the size and scope of the project, each receives the same level of attention to detail and commitment to delivery of a high quality service, within budget and to timelines agreed.

CROMSOURCE has a rich history and the CROM founder, Oriana Zerbini MD, continues at the helm. We have grown steadily to become an organisation of more than 350 experts with offices across Europe and North America with ongoing operations on a global scale, including the Middle East, Africa and South America. Our commitment to providing the right services to support our clients has seen us at the forefront of developments in the Industry; from pioneering the provision of contract staffing solutions in Northern Europe in the mid-90’s, to being early adopters of the ISO Quality Management certification in 2000.
