Ciaran Devane will take on his new role at the head of one of the UK's largest cancer charities in May. Judy Beard, currently acting chief executive, will step back into her previous role as director of fundraising, marketing and communications.
The charity said that Devane's "impressive" track record in strategic leadership and operational management was behind the appointment. Devane worked for seven years at global management consultancy Gemini Consulting, where he became head of the firm's Life Sciences practice, working with multibillion-pound global healthcare and pharmaceutical brands.
This is Devane's first professional role in the voluntary sector, although Macmillan points to his three-year chairmanship of Pavilion Housing Group, a housing association that owns and manages more than 5,000 properties.
"With the number of people living with cancer set to increase massively, I hope to do my part to help Macmillan adapt and grow to meet the challenges ahead," said Devane.
As well as a first class degree in biochemical engineering, Devane also holds a Masters degree in International Policy from George Washington University. Before joining Gemini Consulting, he worked at global conglomerate ICI.
Jamie Dundas, chair of Macmillan, said that Macmillan chose Devane from a very strong field of applicants from across the voluntary, public and private sectors.
Macmillan's former chief executive, Peter Cardy, stepped down at the end of last year. He was named as the new chief executive of the Department for Transport's Maritime and Coastguard Agency in January.
