Holistic Coaching · Physical · Emotional · Mental · Spiritual

Your potential isn’t missing.
It’s waiting to be uncovered.

Lumen is a holistic coaching practice for people who feel the pull toward something more — more clarity, more alignment, more aliveness — but haven’t yet found the path there. We work at the level where lasting change actually happens.

4 PillarsOne integrated path to growth
The Foundation

Growth that touches every part of you.

I.

Physical

Vitality, movement, and rest restored to their natural rhythm — the body as the foundation everything else is built on.

II.

Emotional

The patterns running quietly beneath your reactions, brought into the light and met with steadiness instead of avoidance.

III.

Mental

Clarity that cuts through noise — sharper focus, quieter overthinking, and decisions made from a settled mind.

IV.

Spiritual

A felt sense of purpose and alignment, so each day moves with intention rather than drifting on autopilot.

The Philosophy

Not advice.
A return to alignment.

I started with a question, not a career plan: why do some people change, and others stay stuck doing the same thing for years, even when they desperately want something different?

That question is basically what my Philosophy degree at King’s College London was, even if nobody puts it on the syllabus that way. Philosophy doesn’t teach you facts. It teaches you to pull a belief apart until you find out whether it’s actually true, or just something you inherited. I got hooked on that process, and I never really stopped applying it, even after I left the lecture halls in 2022.

I went looking for the answer in the body first. As a fitness actor and model, and later certified in Boxing Fundamentals and Level 2 Fitness Instruction, I learned what the body is actually capable of once you stop negotiating with it.

Then I went looking for the answer in other people, then in systems. Sales roles at MercyWorldwide taught me how to ask for something meaningful and mean it, and by 2022 I was leading a team, then heading up Athletic Partnerships & Revenue, learning that people move for trust, not spreadsheets. Later, as Sales and Operations Manager at Energie Fitness, I picked up Advanced Sales and Mental Models For Business as formal training, because I wanted language for patterns I’d only felt intuitively until then: motivation without structure collapses fast, but structure without motivation never gets built at all.

From there it was property at Foxtons, then fast-moving business development at Flatpay and Standby24, training in the Art of Negotiation along the way. Different industries, same lesson underneath: every business problem is eventually a people problem wearing a disguise.

“Real change is never just physical, or just mental, or just emotional. It’s all four, moving together.”

And now, the circle has closed. As a Partner with The Juice Plus+ Company and as a Holistic Coach at Lumen, I’m back to the body again, except this time with everything else I’ve learned about belief, trust, structure, and people sitting underneath it. That’s the real timeline. Not a list of job titles, but the same question, asked across a decade of different rooms, until the answer became obvious. That’s the whole idea behind Lumen.

In Their Words

Stories from the path.

Real words from people who started exactly where you might be standing now.

You were one of the first people to get me back in the gym — teaching me the importance of eating, building muscle, and combining weights with cardio. I still use the routine you gave me years later, and the mental and emotional side has transformed just as much as the physical.

I liked that we had a detailed conversation about how I could overcome the obstacles I was facing. You really made me find the root of certain problems and helped me create a plan to navigate them better.

You were a huge support training for my first fight. The exercises we worked on added power and speed that carried straight into sparring — and having clear guidance on how to schedule the training made all the difference.
