Professional profile

I am a Consultant Endocrinologist and General Physician with well established private practice in Spire Gatwick Park Hospital, Horley and The Montefiore Hospital, Hove. I am also a full-time NHS Consultant in Surrey and Sussex NHS Trust. I completed my Specialist training in London/KSS Deanery and was later awarded a Fellow of Royal College of Physicians (FRCP).

I see patients with all types of endocrine, diabetes and general medical conditions, but have special interest in thyroid, adrenal, hyperparathyroidism, neuroendocrine lesions, hyponatremia, PCOS and obesity. I can also see patients with general medical problems, in particular unexplained fatigue. I have patients from across the country and abroad and prides myself in treating patients holistically.

I did period of research in Guildford in gut hormones and insulin related weight gain and I have published extensively and presented in national and international meetings. I regularly lecture in the UK and abroad. I also play an important role in academic training and teaching and I am the Programme Director for Foundation Doctors in Surrey and Sussex NHS Trust.
