Hope joins the military charity from The Defence and National Rehabilitation Centre Capital Appeal.
She replaces Sarah Bryan, who left the charity in May to join TW Cat, a fundraising agency for the not-for-profit sector.
Hope’s move follows her role as chief of staff development for the appeal. Before this, she held the position of director of fundraising at The Royal Hospital for Neuro-disability in London.
Hope said: ‘With the British Armed Forces expected to withdraw from Afghanistan in 2014, it is vital that Combat Stress continues to raise awareness of those veterans who are suffering from service-related mental ill-health and not allow their needs to be forgotten.’
Combat Stress offers treatment and support to ex-servicemen and women with mental health issues such as post-traumatic stress disorder, depression and anxiety disorders.
Combat Stress CEO, commodore Andrew Cameron, praised Hope's ‘vast’ experience of comms and fundraising, which he said will be ‘invaluable’ for the charity.
