Research leader @ Mayo Clinic | Follow me for insights on habits, productivity, and self-actualization | On a mission to normalize health

70% of American adults are overweight or obese. 
40% of cancers are preventable. 
72% of adults report health impacts due to stress.

I've worked with 300+ cancer patients as a health and wellness coach at the Mayo Clinic. 
And I've noticed a few things during this time:

-No one wants to be unhealthy
-Medications and procedures can keep you alive
-But it's lifestyle change that will help you build resilient health

And there's an unfortunate misconception out there that health is difficult to build. 
That "exercise" = self-imposed suffering
That "healthy foods" = kale smoothies
That joint pain is normal. 

But if you've got a demanding professional life, you need to implement low-friction habits and routines to preserve your health. 90 minutes at the gym 5x/week is not an option. 

This is the stuff I help people with. 
Simple health that will last a lifetime. 
So you can back to  your mission. 

Over the course of 12 weeks, we’ll develop habits and routines that will help you lose the weight, dissolve the stress, and reclaim your health. 
Should we talk?

Statins, cholesterol, a trip to the doctor

"In allopathic medicine, we systematically disempower the patient."
(From a meeting with a big time person at a big time institution this morning)

Made me wonder...

Is this intentional?
Who is "we"? 
What would systematically EMPOWERING the patient look like?

I help C-level executives and senior leaders navigate high-stakes technology transformations that are blocking growth, burning capital, and threatening critical milestones.

Companies bring me in when they face complex challenges that sit at the intersection of technology, strategy, and people. My focus is on restoring momentum by architecting solutions and uniting cross-functional teams to execute them.

What I tackle:

- Large-Scale Transformations
Managing the immense complexity of enterprise-wide technology shifts, such as infrastructure migrations or post-merger integrations.

- Technology Crises
Stabilizing systems and projects that threaten launches, funding, or corporate reputation.

- Product Stagnation
Overcoming legacy systems and technical debt that prevent innovation and the release of new features.

- AI Strategy & Implementation
Moving from abstract ideas to a concrete AI roadmap that drives business value.

My approach is built on two axis: 
1/ Immediate results. You need to solve the immediate crisis to survive the day.
2/ Sustainable change. The most durable results happen by helping the right people from different functions to work together and drive sustainable change.

Recent Results & Experience:

- Shaped the digital strategy for a billion-size company, to effectively allocate 8-figure investments and launch their first custom-developed product.

- Initiated and shaped the enterprise-wide AI strategy for a multi-national group, synthesizing over 100 distinct opportunities into a unified, actionable roadmap.

Leadership is not a title.

It is not authority.
It is not seniority.

It is two things.

Vision.
And the ability to communicate it.

Many people have ideas.
Few can paint a picture of a future that does not yet exist.

That’s vision.

Seeing what others don’t.
Connecting dots others ignore.
Believing in outcomes before evidence appears.

But vision alone is not leadership.

If you cannot communicate it clearly,
it remains a private thought.

A leader translates complexity into clarity.

They explain the “why.”
They align people around the “where.”
They simplify the “how.”

Without communication,
vision creates confusion.

Without vision,
communication creates noise.

Strong leaders master both.

They think strategically.
And speak simply.

They see the future.
And make others see it too.

That is how teams move forward.
That is how organizations grow.

If you want to grow as a leader,
ask yourself:

Do I have a clear vision?
And can I communicate it in a way others understand?

Follow Yiorgos Tzirtzilakis for leadership and career growth insights that make your next promotion inevitable.

Micromanaging doesn’t create control.
It creates hesitation.

When every move is questioned,
confidence disappears quietly.

But leadership isn’t about hovering.
It’s about trusting.

The moment you say,
“I trust you,”

you shift the standard.

Ownership increases.
Initiative expands.
Performance rises.

Because empowered teams don’t wait to be managed.
They step up to be accountable.

Control builds compliance.
Trust builds commitment.

And commitment is what actually scales results.

If you want a team that delivers,
start by believing in them.

Quitting a job is not weakness.

Moving on is not failure.

Struggling is not incompetence.

Growth is rarely comfortable.

Careers evolve.
People evolve.
Standards evolve.

What is dangerous…

is staying where your effort is invisible.

Where your ideas are ignored.
Where your growth is blocked.
Where your value is underestimated.

Loyalty should never cost you self-respect.

And resilience should never mean tolerating misalignment.

Strong professionals don’t run from pressure.
They grow through it.

But they also recognize when the environment
is no longer aligned with who they are becoming.

You are allowed to pivot.
You are allowed to outgrow places.
You are allowed to choose environments
that challenge you and respect you.

The goal is not stability at any cost.

The goal is growth with dignity.

If this resonates, reflect on this:

Are you growing where you are?
Or just surviving?

Kind leader vs nice leader there’s a big difference.

A nice leader avoids conflict, sugarcoats feedback, 
and keeps the peace.

A kind leader chooses honesty, accountability,
and growth even when it’s uncomfortable.

Kind leadership isn’t harsh.
 It’s respectful, clear, and rooted in real care for people’s progress.

Because real leaders don’t just protect feelings
they help people improve, take responsibility, and become better.

At the end of the day, leadership isn’t about being liked.
It’s about making a positive impact on your team.

Ask yourself honestly:
Are you being nice or being kind?

Your team is not quiet because everything is fine.

Leadership is not defined by your title.

It is defined by your impact on people.

Here are 11 signs you are the kind of leader others genuinely want to follow:

01/ You protect your team when they are not present.
02/ You give recognition publicly and correct privately.
03/ You take responsibility before assigning blame.
04/ You stop toxic behavior early.
05/ You notice potential others overlook.
06/ You remove obstacles so they can perform.
07/ You remain steady under pressure.
08/ You admit mistakes without ego.
09/ You show up when it matters most.
10/ You build people strong enough to not depend on you.
11/ You do what you say you will do.

I have worked with leaders who had impressive titles
but created fear and silence.

And I have worked with others
who had no formal authority
yet shaped careers and built confidence in everyone around them.

The difference was never competence.

It was intention.

One focused on status.
The other focused on people.

Real leadership is simple:

Your team’s growth is your responsibility.
Their success reflects your direction.
Their trust is your real authority.

Titles are given.
Influence is earned.

Be the kind of leader people grow because of.

7 leadership books.

Leadership is not about authority.

It is about responsibility.

Responsibility for creating safety.
Responsibility for building trust.
Responsibility for thinking long term.

Great teams don’t perform because they are afraid.

They perform because they feel protected.

When people feel safe,
they speak up.
They take risks.
They collaborate.

Trust is not built in big speeches.
It is built in small, consistent moments.

How you respond under pressure.
How you handle mistakes.
How you show up when it matters.

Leadership is also biology.

Recognition increases motivation.
Empathy increases connection.
Shared success increases performance.

And the strongest leaders play the infinite game.

They don’t chase short-term applause.
They build long-term loyalty.
They focus on people, not just numbers.

If you want stronger results,
start by building stronger humans.

Because culture is not an accident.
It is designed by leadership.

5 MOST IMPACTFUL LEADERSHIP LESSON

The worst leader I ever worked with taught me something important.

Titles don’t make leaders.

Actions do.

Anyone can manage tasks, deadlines, and meetings.
But very few people know how to truly lead others.

Real leaders don’t try to control the room.
They create an environment where people can do their best work.

They listen before speaking.
They support instead of blaming.
They stay calm when things go wrong.

And when the team wins?

They step back and give the credit away.

Because leadership isn’t about power, status, or hierarchy.

It’s about people.

It’s about the trust you build.
The example you set.
And the growth you create in others.

At the end of the day, people don’t remember your title.

They remember how you made them feel.

So behave like the leader you once needed.
