Over many years Medex Research executives have built up close working relationships with a team of bilingual medical interviewers who are dedicated to healthcare research in the specific countries. The main markets researched on a continuous basis are: Europe, US, Japan, China, Australia and other Pacific Rim countries.     contact Sarina Masson Medex Research Ltd, 2 Chapel Street Chichester, West Sussex, UK, PO19 1BU Tel: 44 (0) 1243 790779 Fax: 44 (0) 1243 790778 sarinam@medexresearch.com
