I began investing in 2005 while still in medical school. In 2007, I started trading on the Brazilian stock exchange. 

By 2008, I was investing in the forex market using automated robots. For many years, I saw good returns with my stock portfolio in Brazil. 

Through day and swing trading with robots in forex, I had excellent years and others not so much; my results were unstable, though I tended to win more than lose. 

In 2020, I started investing in cryptocurrencies with robots, and in 6 months, I turned $32,000 into over $1 million. I stopped trading and exited this market upon identifying the end of that bull market cycle. 

Also in 2020, I began to study macroeconomics in depth, which became part of my analysis process, using fundamentals in my analysis as well and keeping up with new technologies. This is how I identified opportunities in cryptocurrencies, recognizing a time when the macroeconomic scenario was favorable, blockchain was an emerging technology, and then I developed a portfolio strategy that had an edge in selecting cryptocurrencies. 

Nowadays, my strategy is focused on long/short in the US stock market, aiming to buy (long) the best stocks (usually large tech stocks with high growth potential, solid business moat, but also some excellent defensive stocks) or ETFs of the best sectors and sell (short) ETFs that have poor strategies and/or prospects.

Why I've Been Quiet, and What's Coming Next

This year has been one of the biggest years of my life.

A new baby girl.
Back-to-back Inc 5000 Fastest Growing Companies.
Named a Titan 100 CEO in Philadelphia.
And another big one:
Building a partnership with the American Health at Home Fund.

If you’ve noticed I’ve been quieter on LinkedIn lately, it wasn’t because I lost interest.

It’s because I’ve been deep in the trenches:
 → Due diligence
 → Systemizing operations
 → Financial cleanup
 → Growth strategy
 → Integration planning

And it gave me a MASSIVE perspective shift that I want to share with this community:

Most home care agencies don’t need more clients…
They need to become the type of healthy business buyers look for. 

Not because you want to sell today…

But because when you build like a sellable company, everything gets better:
 • Stronger margins
 • Cleaner numbers
 • Better leadership
 • Less owner stress
 • Higher retention
 • Faster growth
 • A REAL valuation

As owners, we get trapped in day-to-day fires…

But the real wealth in home care comes from building something that can run without you.

Now that the deal is done and our next chapter is underway, I’m coming back here to share:
 ✓ What my experience with a partnership is like 
 ✓ How to increase your valuation
 ✓ What we’re implementing inside our agency
 ✓ What’s working and what’s failing
 ✓ Systems, leadership, and growth strategy
 ✓ The real path to owner freedom

If you’re scaling a home care agency and want to follow the journey — I’m going to lift the curtain on all of it.

Stay Tuned!

“If you want to go fast, go alone.
If you want to go far, go together.”

I’m proud to officially announce our partnership with the American Health at Home Fund.

Their team flew out last week for a full week of collaboration, strategy, and planning — and it couldn’t be a better fit.

At Thema Home Care, we’ve built a strong foundation:
✅ A high-quality premium service
✅ A trusted reputation
✅ A healthy, well-run business behind the scenes

But we’re always focused on what’s next — how to reach more families and raise the bar for care.

With the Fund’s experience, knowledge, and resources, we can now take what’s working and expand it — bringing premium, personalized care to more seniors than ever before.

The goal is simple: maximum impact for the seniors we serve.

This partnership is about scaling excellence — not just growth for the sake of growth.

We’re excited for what’s ahead and grateful to be surrounded by a team that shares the same vision and values.

Here’s to going far, together.

Most home care owners try to scale the business the wrong way.

They think the path is:

More caregivers.
More leads.
More clients.
More everything.

But when you look at the agencies that actually grow through acquisitions…
Or the ones that get attention from buyers…

They’re not focused on getting bigger.
They’re focused on getting cleaner.

Here’s the reality no one tells you:

Buyers don’t chase the largest agencies.
They chase the agencies with the least operational risk.

And operational risk doesn’t show up in revenue.
It shows up in the backend.

These are the agencies that consistently get the highest multiples:

• The org chart runs without the owner
• EBITDA is clear and predictable
• Books are clean (no mystery categories)
• Margins aren’t swinging wildly
• Processes are documented
• Onboarding is repeatable
• Lead flow is systematized
• Staffing isn’t a weekly crisis

In other words:

Not the biggest agencies.
The tightest agencies.

Here’s the mindset shift:

If your business falls apart when you step away…
It’s not scalable.
And if it’s not scalable…
It’s not sellable.

Most owners think they need more clients.
What they actually need is to stop being the glue holding everything together.

When you start building like someone might buy you one day, your entire business improves—whether you sell or not.

Less chaos.
More margin.
More freedom.
Higher valuation.

Build a business a buyer would fight to acquire.
Not one you’re secretly trying to escape.
