After qualifying with a degree in Medical Sciences at the University of Cambridge, Dr Jenkins undertook his clinical training at The Royal London Hospital. Shortly afterwards he joined the internationally renowned Department of Endocrinology at St Bartholomew’s, where he gained unrivalled experience in clinical endocrinology. 

Dr Jenkins would remain at St Bartholomew’s for almost 20 years while running the endocrine service at Homerton University Hospital. Within the Medical School, he served as Dean for Pre-Registration Doctors and led an active research group into the interactions between hormones and cancer. He has published more than 80 peer-reviewed scientific papers in this field as well as writing several books and text-book chapters and was awarded numerous academic grants for his research. 

During all of his clinical career, Dr Jenkins has been passionate about the benefits of early detection of disease and the role that modern imaging can play in healthcare. Over 15 years ago he established the European Scanning Centre in Harley Street and developed this to be the UK’s leading independent diagnostic imaging company. 

In 2006, in order to complement ESC, he established Echelon Health. This enables him to combine his 30 plus years of clinical practice with state-of-the-art imaging to provide world-class preventive health assessments. He has enormous experience of treating patients with post-viral fatigue syndrome, having managed several hundreds of patients with this condition, something which shares many features with Long Covid.

In October 2021, Dr Jenkins appeared on a Leaders Council of Great Britain & Northern Ireland podcast, discussing the importance of preventative medicine and leadership and the impact both have had on his career to date.
