About Us

In July 2016 Seagrave Healthcare Limited opened The OAD Clinic in Central London, bringing together over 30 years of clinical excellence in treating alcohol and drug related problems, anxiety, depression and opioid analgesic (painkillers) dependence.

Our team of expert consultants, pain specialists, nurses, psychologists, counsellors and health care advisers have many years of experience treating addiction, mental health and complex pain.

We use a multidisciplinary team approach, customising evidence based treatments to support each individual’s unique capacity to thrive and live a fully functional lifestyle.

This approach results in positive outcomes for people who suffer from alcoholism, drug addiction, depression, anxiety, trauma, chronic pain, and other disorders. We are dedicated to treating the whole person with bespoke care plans and treatments.

The OAD Clinic team is led by Dr Oscar D'Agnone, MD, MRCPsych, Consultant Psychiatrist, member of the Royal College of Psychiatrists, is regulated by the Care Quality Commission, and compliant with the General Medical Council code of Good Medical Practice.

Dr D'Agnone is Medical Director of The OAD Clinic and CEO of Seagrave Healthcare Ltd.


The OAD Clinic is based in Belgravia, one of London's most exclusive neighbourhoods less than 5 minutes walk from Victoria station.
