Mark Green

CEO at Change Rebellion

Farnham, United Kingdom

I’m the CEO of the award winning Change Rebellion, home of change management specialists who prefer straight talking over jargon and empathy over ego.

We guide people through organisational chaos with honesty, humour, and a healthy respect for what actually works.
No nonsense, just proper human-centred change, done well.

Although my caffeine consumption rivals that of a small European country, I love what we do and what we do is help people in the workplace.



With more than 20 years of experience in business change management, Mark established Change Rebellion in 2023 following his recovery from a two-month long induced coma after falling seriously ill with COVID-19.

Having become uninspired by the industry and spurred on by his experience of ill-health, Mark decided to go it alone, using his honest and empathetic approach to support workplace transformations with tangible results.

Now supported by a growing team of like-minded consultants, Mark is fast becoming a leading voice for the sector, where his straight-talking, honest and transparent approach has not only been recognised by large industry players, but also household brands looking for an impactful change management strategy.

Five ways to fail
Entrepreneur.com
November 19, 2025
Evolution is something that every single business experiences, so you might expect that there are a million reasons a change management project could fail. But we know that each project boils down to the same two facts: something is going to be different, and it's going to affect people working within that business. All of which means that when we analyse the projects which didn't have the intended outcome – where the change was ultimately reversed, where it was fiercely resisted, or where the timescale or budget spiralled out of control – there are a few causes which crop up alarmingly often. By being aware of some of the most common factors influencing failure, it doesn't guarantee that all change programmes will run without a hitch – but it can help you avoid the pitfalls that hundreds, if not thousands, of companies have fallen into before you.

Why you shouldn’t need a consultant to help you through
EU Business News
November 18, 2025
It may seem odd for a change management specialist to recommend that a company develops its own in-house capabilities. Why would someone who gets paid to swoop into a business and save it from a transformational nightmare give out this kind of advice?

Building the Case for Human-First Consulting.
Business Circle
November 06, 2025
The consulting world has long been known for its buzzwords, complex processes, and high fees. For many organisations, change
programmes have become something to endure rather than embrace - long, expensive journeys that often deliver more paper-
work than progress.

The Power of Simplicity in Leading Change
CEO Monthly
October 21, 2025
In the world of change management, leaders have become far too used to simply telling people things are going to be different. Even worse, they often quote models with three, five or maybe even eight steps, they share complicated frameworks, and they expect employees to understand an entire dictionary of jargon and acronyms.

That’s not working. No matter how many certificates you have, change management courses you’ve attended, or books you’ve read, it simply isn’t translating because the whole process is being made unnecessarily complex, and the simple ‘why’ and ‘how’ explanations are being hidden away as if they’re state secrets.

You’re so vain, I bet you think this change is about you
Business Age
September 26, 2025
When it comes to overseeing a big change within your company, it’s very easy to cast yourself as the main character - you have a clear vision in your mind about what will work, how you’ll implement the plan, and how long it will take to do so. You might even be picturing yourself as the hero of the hour, with a dazzling project that will be completed in the blink on an eye, and on budget too – even if the finance department has allocated you the smallest pot of money ever seen in the history of change management projects.

The problem? Everyone else in the company has an opinion about the change too, whatever that change might be: a new software roll-out, a merger, or a full-scale rebrand.

Starting all over again with Mark Green
Another Door
October 01, 2025
“There were two significant moments, two significant doors. One was the thought of that's it. I'm dead. Door closed on everything. And the other moment was when the consultant said, you can have all this back. You've just got to work for it. Door open.”

In this episode, Mark Green, founder of Change Rebellion shares his wild story of a door closing, nearly for good, and how it changed him and his perspective for life. It’s not just a story about navigating professional change; it’s about survival, resilience, and finding purpose.
