Dr J S Grewal


Consultant Psychiatrist

I grew up in Berkshire and studied Medicine in London.


I am a Consultant Psychiatrist working in a full time NHS post in Urgent Care Psychiatry.


I am the Consultant Psychiatrist for The Charterhouse Clinic, ESH Community and Bayberry and I have my own private practice in Coventry/Warwickshire and The Midlands.


I qualified as a doctor with a Bachelor of Medicine and Surgery (MBBS) degree in 1993 from The Royal Free Hospital School of Medicine, London. I worked for 9 years in various hospital posts before specialising in Psychiatry.

PA to Dr Grewal

I grew up in Nykøbing Mors in North Jutland. A small fishing town on the coast in the North of Denmark.


I studied Pure Maths at The University of Copenhagen; and then completed a Master’s in Economics and Business Administration/Finance and Investments at The Copenhagen Business School (CBS).


I then spent 3 years working in the Banking/Finance sector in Zurich and Frankfurt…often spending 16 hours per day in the office! 

I took 3-months off work- mostly reading (spirituality books and novels), training (tennis and yoga), spending time with family/friends and reflecting. I realised there must be more to life than chasing money and working within that unhealthy culture. 


An emergence of a new spiritual consciousness has brought me to England to study Integrative Psychotherapy and Philosophy. I had also planned to spend the summer at various music festivals…but that did not work out so well!


My interest in Eastern spirituality and psychology has initiated a daily meditation practice; in particular the study of Tibetan Mahamudra and Dzogchen.
