methodology in service of it.
No two organisations change the same way — so I don't run the same playbook twice.

Trusted at senior level

A decade advising C-suite sponsors and programme leadership — at Deloitte, A.T. Kearney and UBS, and on programmes touching a thousand-plus stakeholders. I'm used to the room where the stakes are highest and the scrutiny is real.

I speak business and system

Where many change and project leaders keep technology at arm's length, I lean in — holding my own with technical teams, understanding what your systems actually do, and translating fluently between the people building the solution and the people who'll use it.

Adoption that outlasts go-live

Structure and a human touch, in equal measure. Proven method matched to real experience — so change doesn't just launch, it sticks, and the benefits you invested in actually land.

Frequently Asked Questions

Answers to some of the most common questions about how I work, when to involve a change consultant, and what you can expect from our collaboration.

Not at all. While most of my experience comes from complex international programmes, I also support smaller organisations and individual initiatives. The approach is always adapted to the size, complexity, and objectives of your project.

Yes. Many clients already have capable internal teams and simply need additional expertise, an independent perspective, or temporary support. I can complement your existing resources without replacing them.

Every organisation has its own culture, pace, and way of working. Rather than applying a fixed methodology, I combine proven frameworks such as Prosci ADKAR with practical experience to build an approach that fits your organisation and delivers sustainable adoption.
