Acosia represents the very best of NHS leadership and the nursing profession. It has been a pleasure and a privilege to work alongside her as a valued member of our Board of Directors at Sussex Partnership. 

Whilst I am sad to lose Acosia from Sussex Partnership, I am incredibly proud to see her talent recognised and her achieve this promotion. Whilst leaving us Acosia will remain part of our South East NHS and care family and I look forward to continuing to work with her in this capacity.”

Acosia Nyanin said:

“I feel truly privileged to have worked with the team at Sussex Partnership as Chief Nursing Officer. Given the challenges we have faced over the last year – and continue to manage – in the midst of the Covid-19 pandemic, I couldn’t be prouder to be a nurse working as part of our wonderful NHS. 

Our staff have been incredible in doing everything possible keep patients, families and carers feeling safe and supported. Their commitment, compassion and team work is truly inspirational. I am particularly inspired by and thankful for what our staff across mental health and learning disability achieve, every day, on behalf of the local communities we serve.

I will continue to do everything I possibly can to support them, both during my remaining time at Sussex Partnership and in my new role at NHS England and Improvement.”
