Terrence Higgins Trust (THT) chief executive Ian Green is to step down after leading the sexual health charity for almost seven years.
He will leave early next year after his replacement is recruited.
Prior to leading the charity he used its services after being diagnosed HIV positive in 1996.
Green is leaving to take up a global leadership role with Prevention Access Campaign, which raises awareness of the undetectable = untransmittable campaign, whereby a person with HIV who is being treated and has undetectable viral load cannot sexually transmit the virus.
"It's with very mixed emotions that I'm making this announcement,” said Green.
“As someone living with HIV for over a quarter of a century, it's been the privilege of my career to lead this life-changing organisation at such a crucial time. I'm deeply proud of what's been achieved in the last seven years and know I'm leaving the charity in a strong position to achieve its mission of ending new HIV cases by 2030."
NEW: Our Chief Executive @ianrgreen is to step down after leading our charity for nearly seven years.— Terrence Higgins Trust (@THTorguk) September 5, 2022
Ian was diagnosed with HIV over 25 years ago and has been our CEO since 2016. We thank him for his drive, passion and commitment. He will be greatly missed.
THT chair Johnathan McShane added: “Ian has not only taken Terrence Higgins Trust from a difficult point in our history and through challenging times, he has been a Chief Executive with real vision.
“His legacy goes way beyond the organisation. His leadership ensured Terrence Higgins Trust was the first HIV charity in the world to embrace the ‘Undetectable Equals Untransmittable’ science and develop the ‘Can’t Pass It On’ campaign.
“Ian will be sorely missed but he should be proud that he will leave an organisation better equipped than ever to make a real difference to people's lives."
