CROMSOURCE was established in Europe more than 25 years ago when the first clinical operations office was opened in the historical center of Verona, Italy.
Shortly afterwards, the Company expanded into Central and Eastern Europe establishing the first subsidiary in Warsaw, Poland, and so becoming one of the first CROs to be active in this region. CROMSOURCE has grown organically over the years and now has 12 offices and teams located in the strategic hubs of Europe as well as a strong operational presence across two offices in North America. From it’s inception, CROMSOURCE was built on a foundation of quality, stability, integrity, and high levels of customer satisfaction – all of which have led to a high rate of repeat business. Together with the long tenure of many of our team members this means that the expertise and experience of more than 25 years of conducting clinical research in Europe is not just ‘on paper’, but is solid and available within our team.
