Our Company

Sequani’s heritage spans more than 40 years when a company called Toxicol Laboratories opened for business in London before moving to the company’s current site in Bromyard Road, Ledbury.  A little while later we went on to join IQVIA (Quintiles); a venture destined to grow into one of the largest contract research organisations in the world. 

The name Sequani dates back to the year 2000 when, after seven years of association with IQVIA, the company changed ownership under a new identity. Way back in history, Sequani was a Celtic tribe made famous for harrying invading Romans during their suppression of Gaul. We feel the name is apt as we too give the big boys a run for their money!

We achieve this by working closely with you to deliver flexible and fast solutions that help keep your development programmes on schedule. Our customer feedback consistently shows that the service and commitment our clients enjoy is the most personal and direct in the business. But we take none of this for granted. Our focus is continuous improvement so that we carry on growing through the repeat business of loyal customers as well as attracting business from new clients
