Women in the COO Community
WCOOC
Supporting, empowering & inspiring the female leadership of tomorrow
Its purpose is to champion the cause for advancement of women within financial services, focused on the leadership of tomorrow, those that will take the industry forward into the coming age.
Members of our global COO network come together to provide and present on subjects directly related to career management and advancement. We provide this through articles, interviews, and events for which we recruit engaging speakers from within and outside the industry. We welcome people of any level of seniority to engage with our agenda.
WCOOC is led by industry professionals, its Chair, Vice Chair, and regional steering groups working together to provide timely and forward-thinking content and thought leadership.

Confidence Clusters
To support our executive female COO community members, we provide Confidence Clusters. Each cluster of six managing director COOs remains the same over a 12-month period, meeting every quarter for a 60-minute on-line exchange.
This safe space allows our female members to engage with a peer group with confidence and in-confidence on common challenges.
How does this work?
Frequency: The group meets once every quarter.
Confidentiality: Discussions are held in a safe space under the Chatham House Rule, ensuring privacy.
Commitment: The same six members will participate for a full year, promoting continuity.
Duration and Agenda: Each meeting lasts 60 minutes, with topics submitted in advance or raised spontaneously.
Scheduling: Meetings for the upcoming year are confirmed week 1 January.
Support: Armstrong Wolfe will manage logistics and documentation, including noting action points and providing feedback to the WCOOC Chair.
WCOOC: The Next Decade
Anchoring WCOOC’s purpose & direction for the future
2026 marks the tenth anniversary of Women in the COO Community. In 2016, Armstrong Wolfe’s CEO, Maurice Evlyn-Bufton, wrote an article titled ‘The Case for Equity-Plus Representation for Women in the COO Community.’
Maurice had spent 15 years in executive search, focusing principally on business management roles – the Chief Operating Officer, the Chief Administration Officer, Chief of Staff, and Chief Control Officer. After interviewing and referencing hundreds, if not thousands, of COOs, he concluded that women make better COOs – the question was: why?
In his paper, Maurice interviewed 50 female managing director COOs and most of their managers to investigate his belief. The conclusions were summarized in his paper, which, when presented to the then Group COO at Standard Chartered Bank, Doris Honold, prompted the comment: “WCOOC – we should do something with this.” Maurice asked, “WCOOC, what is that?” to which Doris replied, “Women in the COO Community.”
Three months later, Doris hosted the first event, and from this, Armstrong Wolfe’s inclusivity initiative was born.

“I would like to take this opportunity to thank all those who have supported WCOOC on its ten-year journey. Specifically, I would like to thank Emma Prophet, the outgoing 2025 WCOOC Chair, who has done wonders in taking WCOOC into its anniversary year. I also want to welcome the 2026 Chair, Penny Tunbridge.
Appropriately, Penny was a panellist alongside Doris at WCOOC’s inaugural event in 2016 and has been a mainstay and advocate for its work throughout its journey. I very much look forward to working with the three regional and global steering groups in the year ahead as we celebrate ten years of playing our part in seeking equality of opportunity for women in financial services, while promoting the COO role as a career destination for tomorrow’s rising leadership.”
