Having gained over 30 years of experience, initially at ICI (now AstraZeneca) and then at Serono, John became a freelance Clinical Research Manager in 1996. He founded Clinical Development and Support Services Ltd (CDSS) in 1998. John spent 10 years teaching on the MSc in Clinical Research, Diploma and Certificate courses at Liverpool John Moores University, and is still an honorary lecturer there. He was on the executive committee of the Association of Clinical Research in the pharmaceutical industry (now the Institute for Clinical Research) for 6 years.
Whilst gaining his Institute of Directors Diploma in company direction, John continued to oversee the steady expansion of CDSS, promoting the company both within the UK and overseas to the biotech, pharmaceutical and medical device industries and is a familiar and respected face at conferences, exhibitions and seminars all over the world.
