Hi, I’m Wen.
After 15+ years across academia and industry in life sciences, I now work as a Human Performance Partner—supporting people and teams in knowledge-intensive environments to protect focus, strengthen decision quality, and build an operating rhythm that doesn’t rely on overdrive.
I’m a nature person. I photograph and paint landscapes, and I often return to the way plants grow: quietly, consistently, without force. I still believe the best human conversations happen slowly, in real presence.
AI is raising the baseline of work. The real differentiator isn’t more information—it’s the human layer above it: judgment, decision quality, and a rhythm that holds—especially when work speeds up with AI and complexity.
That’s where I work: not in theory, but in real days.
Leiden—Wassenaar—The Hague, with clients locally and globally.
How I See My Role
I don’t see myself as a fixer or a motivator.
My role is to be:
-
a quiet guide — steady, present, unhurried
-
a thinking partner — helping you turn insight into clear decisions and next steps
-
an inner mapmaker — making complexity visible through simple visual frameworks
-
a keeper of rhythm — supporting consistency until it becomes natural
In practice, this means:
-
I listen beyond the surface story
-
I reflect patterns in your language, energy, and choices
-
I simplify complexity into something you can work with—immediately
-
I walk beside you—so your next chapter unfolds with clarity, not force
You bring your life and work.
I bring structure, depth, and a way of seeing.
What I Do
Through visual coaching, I design minimalist life-and-work ecosystems—grounded in scientific depth and human-centred elegance—so your next chapter feels clear, calm, and livable in an AI-accelerated world.
I help you move through a simple arc:
Knowing → Doing → Living
-
Knowing
We reduce noise and name the real pattern—so you regain clarity, and reconnect with what’s transferable: your strengths and values.
-
Doing
We turn clarity into clean decisions and practical next steps—so progress fits your real workdays, not an ideal schedule.
-
Living
We install a sustainable rhythm that holds—so execution stays steady even when motivation drops, pressure rises, or life becomes full again.
Foundations of My Work
My approach is the meeting point of four disciplines.
Scientific Depth
Trained in neuroscience, medical biology, and lifestyle medicine, my work is grounded in scientific inquiry and evidence-informed understanding.
Every insight, tool, and method is anchored in how the human system actually works — biologically, psychologically, and energetically.
Nordic Clarity & Human-Centred Excellence
Shaped by my high-performance training with Hintsa,
a Nordic, human-centred performance methodology trusted by Formula 1 and global business leaders for over 30 years.
My approach combines clear structure with human-first design — elegant, simple systems that bring people back
to what genuinely matters.
Eastern Subtlety & Inner Power
Not through concepts or terminology,
but through the quiet order of the work:
we begin with essence,
let structure follow,
and allow rhythm to grow naturally.
Visual Coaching
My artistic passion enables me to translate your inner landscape into clear visual frameworks —
So you can see the bigger picture:
what is shifting inside you,
what your next step requires,
how everything connects,
and where the actions that matter most truly lie.
Together, these elements create a powerful and deeply human pathway for turning insight into action — and action into a rhythm people and teams can sustain.
Amstara®
— What It Stands For
Amstara® brings together three quiet forces:
Ambition — the desire to grow into your next chapter
Stamina — the steadiness to walk it with clarity and strength
Ra — the ancient symbol of the sun, renewal, and inner illumination
But Amstara is more than a name.
It is a way of approaching life
where growth doesn’t come from pressure,
but from alignment.
It is built for people who refuse to choose
between ambition and well-being,
between achievement and inner grounding,
between success and a life that feels true.
For those who carry the stamina to continue,
the sensitivity to evolve,
and the quiet courage to let their inner world lead the way.
Amstara is a gentle invitation:
to turn transition into transformation,
stress into strength,
and the inner shift you feel
into the life that is ready to unfold.
