Getting Senior Leaders to Optimal Performance and Sustainable Growth Without Burnout

You’re capable, experienced, and used to handling pressure. Yet certain moments quietly destabilise even strong leaders.
► When you step into a new role and realise the rules have changed
► When a restructuring, missed promotion, or sudden shift knocks confidence more than you admit
► When performance still looks “fine”, but decision-making feels heavier and slower than it should

These moments don’t look dramatic from the outside. 
They look like coping.

And this is where many leaders hesitate —
waiting for clarity to return on its own,
until the cost shows up as loss of judgment, credibility, or energy.

👉 This is where my work begins.
I partner with senior leaders and leadership teams during high-stakes transitions — where clarity, authority, and direction matter more than speed.

My clients typically come to this point when they need to:

✔️ Make clear, grounded decisions under pressure 
✔️ Re-establish authority and presence in a new or changing role 
✔️ Navigate career transitions or restructuring without loss of momentum 
✔️ Lead teams through complexity, transformation, or sustained change 
✔️ Perform at a high level without sacrificing health, focus, or integrity

I bring 17+ years of experience from Fortune 500 organisations (P&G, General Mills, GSK, Syngenta), combined with professional executive coaching and mentoring (ICF PCC, EMCC SP). 

I understand the realities of senior leadership — competing priorities, political complexity, and the expectation to “hold it together” while everything shifts.

My clients often describe the biggest shift not as improved performance alone — but as clearer thinking, steadier confidence, and the ability to lead without constantly operating in reactive mode.

If you’re navigating a meaningful transition — whether you’re still in role or between chapters — and sense that waiting is no longer the right strategy, you’re welcome to message me here on LinkedIn to explore whether working together makes sense.

Most of the leaders I work with aren’t stuck 
because they are not thinking enough.

They see what’s no longer working.
They understand the implications.
They have ideas to test.
They’ve thought it through - repeatedly.

What’s missing isn’t insight.

It’s a space where clarity turns into decisions,
and decisions turn into movement -
without rushing, proving, or forcing outcomes.

Some moments don’t need more effort.
They need the right kind of containment.

P.S. If something you’ve been circling feels ready to be addressed, this is the kind of transition that benefits from the right container.

Between roles many leaders feel an invisible clock ticking.

They don’t want to rush.
They don’t want to repeat old patterns.
But they also don’t want to get stuck.

So they stay busy instead.

Networking.
Thinking.
Sending applications daily.
Scrolling LinkedIn.

Yet the discomfort isn’t really about time.
It’s about not having enough structure for the transition.

Without that, even thoughtful leaders start doubting themselves.

This is where transitions quietly stretch longer than necessary -
not because skills are missing,
but because support is.

P.S. Being between chapters isn’t a gap to fill. 
It’s a phase to take seriously.

And waiting won’t make it calmer.

Many people are waiting.

Waiting for the market to improve.
Waiting for work to slow down.
Waiting for life to feel easier before they finally breathe again.

They hope the waters will calm.

But life is rarely a quiet lake.
Most of the time, it’s a wavy ocean - 
unpredictable, demanding, alive.

And while you’re waiting for perfect conditions,
your life is still passing by.

Sustainable growth doesn’t come from hoping the waves disappear.
It comes from learning how to surf.

From building balance, clarity, and resilience 𝘪𝘯𝘴𝘪𝘥𝘦 you -
so you can navigate change without burning out
and even enjoy the ride.

Many senior leaders don’t collapse.
They continue performing.

What changes first is something quieter.

Decisions take longer.
Recovery takes more effort.
Quality thinking time disappears.
Weekends bring more screen time than joy.

They tell themselves it’s temporary.
That pressure comes with the role.

Sometimes that’s true.
Often it’s a signal.

Sustainable growth isn’t about pushing less.
It’s about noticing when the cost is no longer worth the output.

That moment is easy to rationalise away -
until it forces a decision later, 
under worse conditions.

P.S. If the price of “doing well” has been rising for a while, it might be asking for your attention now.

Scroll through LinkedIn on any given day and you’ll see it.

New role announcements.
Promotions.
Bigger titles.
Public celebrations of progress.

Most people could make these updates invisible - 
but they don’t.

Because being seen, acknowledged, and validated matters.
That’s human.

What we don’t talk about enough is the other side of those posts.

The quiet comparison they trigger in leaders who are already carrying a lot.

𝘞𝘩𝘢𝘵 𝘥𝘰𝘦𝘴 𝘵𝘩𝘪𝘴 𝘴𝘢𝘺 𝘢𝘣𝘰𝘶𝘵 𝘮𝘺 𝘷𝘢𝘭𝘶𝘦?

These questions don’t stop early in a career.

I hear them from VPs, CEOs, and founders -
especially in moments of transition.

The problem isn’t ambition.

The problem is the false idea that there’s a universal success ladder we’re supposed to follow.

There isn’t.

Careers are not straight lines.
They pause, accelerate, reset, and sometimes fall apart - 
often for reasons far beyond effort or talent.

When you measure yourself against someone else’s highlight reel, you risk seeing personal failure where there is none.

You’re not late.
You’re not early.

You are where your life has brought you - 
and you still get to decide what comes next.

𝐏.𝐒.  Which “should” have you been carrying that no longer serves you?

It’s not because you’re unprepared.
Or lacking confidence.
Or suddenly less capable.

It’s because you’re stepping into a system that already exists -
with unspoken expectations, inherited dynamics, 
and histories you didn’t create.

You’re being read before you fully understand the context.
Your decisions matter before you’ve had time to see the full picture.

And the pressure to “add value quickly” is constant, 
even when no one says it out loud.

Most leaders respond by accelerating.

They work harder.
They say yes more often.
They try to prove themselves early.

But early overcompensation is how misalignment starts.

The leaders who land well do something different.

They slow their thinking before they speed up their actions.
They take time to understand what’s really being asked of them, 
not just what’s written.

They decide what not to change yet.

This isn’t about confidence.
It’s about orientation.

The first moves you make set patterns that last far longer than people expect.

P.S. If you’re stepping into something new and feel the pressure to get it “right” quickly, that’s not a flaw. It’s the moment.

A professional woman stands by a large window overlooking a lake and mountains, reflecting quietly before stepping into a new role.

Very few talked about what that reaction reveals about leadership.

When Emmanuel Macron wore sunglasses indoors at Davos, 
the world listened - and still speculated.

And this is the interesting part:
an explanation had already been given.

It was presented as a benign eye issue -
nothing strategic, nothing symbolic.

Still -

Memes spread.
Commentary escalated.
The company behind the sunglasses saw its share price jump 28%.

Not because eyewear matters -
but because when a leader breaks an unspoken norm, 
explanation alone doesn’t stop interpretation.

This happens inside organisations every day.

A leader goes quiet.
Delays a decision.
Shows up differently than expected.

Even when there is a rational reason,
the system keeps reading signals.

Stories fill the gap:

– “Something’s off.”
– “A restructuring is coming.”
– “There must be more going on.”

The real risk for leaders isn’t deviation.
It’s assuming clarity has been received just because it was provided.

Strong leadership isn’t about over-explaining.

It’s about recognising when perception has momentum -
and choosing whether to actively frame it, hold it, or redirect it.

Because whether you intend it or not,
people are always reading the signals.

PS: Where have you seen a small, unintended leadership signal take on disproportionate meaning?

Many leaders value reflection.

They think deeply.
They notice patterns.
They see what’s no longer working.

And then… they wait.

They tell themselves they’re “not ready yet”.
That they need a bit more time.
That there’s something urgent to take care of first.
That they’ll figure it out.

But insight has a shelf life.

What starts as awareness slowly turns into friction.
The same questions resurface.
The same tension returns, just louder.

At some point, not acting costs more than acting.

The tricky part is that nothing breaks immediately.

You keep functioning.
You keep thinking about it.
You keep living your life.

But over time, the cost shows up elsewhere -
in energy, focus, and the quality of decisions.

That’s when waiting stops being a pause
and starts shaping the outcome.

P.S. If something has been unaddressed for a while, this might be the moment it’s asking for a different response from you.

Most leaders prepare hard for interviews.
Very few prepare for what comes after.

They step into a role already moving.
With inherited dynamics they didn’t design.
And expectations that aren’t fully spoken.

So they compensate early.

They try to add value fast.
They change things quickly.

And sometimes… 
they lock in patterns they later have to undo.

The leaders who land well don’t rush alignment.
They create space to think before they accelerate action.

That window is brief.
And often underestimated.

P.S. If you’ve recently stepped into a new role and feel the pressure to move fast, this is the moment I help leaders slow their thinking before their actions lock in.
You don’t need to navigate it alone.

Many senior leaders look like they’re doing fine.

They deliver.
They show up.
They keep things moving.

But privately, the cost is rising.

More effort to stay focused.
More recovery time after non-stop meetings.
Less space to think clearly.

They tell themselves:

“𝘛𝘩𝘪𝘴 𝘪𝘴 𝘫𝘶𝘴𝘵 𝘢 𝘥𝘦𝘮𝘢𝘯𝘥𝘪𝘯𝘨 𝘱𝘩𝘢𝘴𝘦.”
“𝘐 𝘴𝘩𝘰𝘶𝘭𝘥 𝘣𝘦 𝘢𝘣𝘭𝘦 𝘵𝘰 𝘩𝘢𝘯𝘥𝘭𝘦 𝘵𝘩𝘪𝘴.”
“𝘖𝘵𝘩𝘦𝘳𝘴 𝘴𝘦𝘦𝘮 𝘵𝘰 𝘮𝘢𝘯𝘢𝘨𝘦.”

High performance can mask misalignment for a long time.

Until one day, the question shifts from

“𝘊𝘢𝘯 𝘐 𝘥𝘰 𝘵𝘩𝘪𝘴?”
to
“𝘋𝘰 𝘐 𝘸𝘢𝘯𝘵 𝘵𝘰 𝘬𝘦𝘦𝘱 𝘥𝘰𝘪𝘯𝘨 𝘪𝘵 𝘵𝘩𝘪𝘴 𝘸𝘢𝘺?”

That’s not weakness.
That’s information.

P.S. Where has “pushing through” quietly become your default?

𝐓𝐢𝐦𝐞 𝐢𝐧 𝐭𝐫𝐚𝐧𝐬𝐢𝐭𝐢𝐨𝐧 𝐢𝐬𝐧’𝐭 𝐝𝐚𝐧𝐠𝐞𝐫𝐨𝐮𝐬. 
Poor positioning is.

Most senior leaders don’t struggle because transitions take too long.
They struggle because they stay too broad for too long.

Time itself isn’t the problem.
Ambiguity is.

When your message sounds like:

“𝘐’𝘮 𝘰𝘱𝘦𝘯.”
“𝘐 𝘤𝘢𝘯 𝘥𝘰 𝘴𝘦𝘷𝘦𝘳𝘢𝘭 𝘵𝘩𝘪𝘯𝘨𝘴.”
“𝘐’𝘮 𝘧𝘭𝘦𝘹𝘪𝘣𝘭𝘦.”

You make it harder for others to place you -
and easier for the wrong opportunities to absorb your energy.

At senior level, clarity isn’t a constraint.
It’s a service.

The leaders who land well don’t rush.
They narrow deliberately - often with support - 
long before urgency starts making decisions for them.

The right support doesn’t just protect the outcome.

It sharpens positioning 
and that’s what changes the timeline.

If this resonates, you’re already thinking at the right level.

When an organisation goes through transition - 
a leadership change, restructuring, strategy shift - 
the impact isn’t limited to roles or org charts. 

Team dynamics change first. 

What I often observe is not open resistance, but subtle shifts: 

– Decision-making slows 
– Ownership becomes blurred 
– Informal leaders go quiet 
– High performers start self-protecting 

On the surface, work continues. 
Underneath, alignment erodes. 

This isn’t a people problem. 
It’s a leadership transition problem. 

Teams need clarity on: 

– what still matters 
– what has changed 
– where decisions now sit 
– and what “good performance” looks like in the new context 

Without that, leaders spend months compensating with more meetings, more pressure, and more effort - 
often burning out their best people in the process. 

Sustainable leadership in transition isn’t about pushing harder. 
It’s about stabilising the system so people can perform again. 

That’s the work I do with leaders and organisations navigating change.

They notice when something starts to feel off.
When the role demands more than it gives back.
When effort increases but clarity doesn’t.

What’s harder is knowing how to respond in that moment.

Do you pause and think it through alone?
Do you give it time, hoping the pressure will ease?
Do you reach for an external perspective or structured support early enough?

I see very capable leaders make very different choices at this point.

And those choices quietly shape how long transitions last and how costly they become.

I’m curious what tends to be true for you in practice, not in theory.

When you realise something in your career is no longer sustainable, what do you tend to do first?
