Alison Islin


I was a Trustee for the Board of Trustees for Mind in Barnet and now a Trustee of Mind in Enfield and Barnet. I am a Service User, having lived with OCD and Depression since I was 7 Years Old. I have been involved with Barnet Voice for Mental Health, Service User Group, around 26 Years. During that time, I joined EMU, the Enfield Service User Group where I attended the Acute Wards at Chase Farm Hospital weekly for 2 Years. I have sat on a number of Committees. I feel my biggest achievement is in convincing Barnet Voice, as an organisation, to take action on the often neglectful and abusive behaviour that patients can experience on the Wards. I have founded, and run, the OCD Support Group at The Priory – North London, for 29 years, it is now officially the longest running OCD Support Group in the UK. I have worked closely with Professor David Veal, leading Physiatrist in OCD and BDD and given lectures. This has helped to validate my sense of self-worth. I am a published Author, writing about my journey through life living with OCD.

I have been married to Brian for 36 Years and we have raised two adult sons, Mark and Mitchell, who are both married with children.
