Regulated by the Care Quality Commission


I am a consultant psychiatrist specialising in older adult’s mental health. I qualified as a doctor from Charing Cross Hospital Medical School in 1986. After further training as a physician I undertook training in psychiatry in Liverpool before a series of academic appointments at Charing Cross Hospital, Royal Free Hospital and then Imperial College London.

I have been a consultant psychiatrist at Central North West London Foundation Trust since 1998 specialising in diagnosis and treatment of dementia, depression, psychosis and other mental illnesses. My training as a physician as well as a psychiatrist enables me to provide holistic care for my patients.

I was elected as chair of the Faculty of Old Age Psychiatry at the Royal College of Psychiatrists in 2012, I am the UK representative for Old Age Psychiatry in the World Psychiatric Association and was appointed National Professional Advisor for old age psychiatry at the Care Quality Commission in 2014. I am also the Medical Director of Halcyon Doctors.

Private Practice

I welcome new private patients in London and East-Anglia and accept self-referrals, referrals from general practitioners as well as instructions from solicitors.  I would prefer to see you at your own home because it enables a more comprehensive assessment and it is often more convenient for you. Alternatively, appointments can take place in several consulting rooms across London and East-Anglia.


I use the latest diagnostic techniques to assess your symptoms and, if necessary, can draw from a plethora of treatment options.


I aim to see you in a matter of days, and send my letter or report within a week after the appointment.


I strive to fit my service around you, scheduling appointments where and when suits you best.


I provide a comprehensive assessment, clear diagnosis as well as bespoke treatment and care.

I am part of Halcyon Doctors, a team of accomplished consultants and other specialists who provide home-based healthcare services across England and Wales. We are approachable, compassionate and solution-oriented, and believe that excellent clinical expertise goes hand in hand with exemplary customer service.
