Private & Business Banker

Growth Partner for 7-Figure CPA Firms | Ads & AI Automations Helping Firms Grow from $1M → $3M+ | Built 7–8 Fig Businesses | Ex-Private Banker | Founder | Investor

I skipped the safe path and built my own.

From private banking suites to private acquisitions, I’ve spent over a decade scaling founder-led businesses that move fast and grow with clarity. 

→ 7 years in private banking, advising high-net-worth clients at top-tier institutions

→ 10 + years running & growing 7 and 8-figure brands with the right talented people, smart systems, and real strategy

→ Now, Founder of Black Sterling Group, scaling and acquiring financial services & fintech firms between $1M–$10M

What I Do:
I help CPA firm owners scale with clarity, automation, and strategy, so they can grow with less stress and more options.

→ I run paid ads that bring in real, qualified leads 
(Key word: qualified) 

→ I build systems and AI workflows that cut 10–20 hours of admin a week

→ I elevate brands to attract premium clients and prep for legacy or exit

→ I buy firms ready to scale or transition into something bigger


Simple systems. Profitable growth. Clean exits.

But this isn’t just strategy, it’s personal.

In 2015, I took a solo trip to Australia and Bali that reframed everything. I realized the most important transformation isn’t operational, it’s internal. (Ask me about it) 

That’s why I write Letters to Ego, a founder-focused newsletter on identity, clarity, and the mindset behind high-performance leadership.

Let’s connect if you’re:
→ A CPA, CFO, or firm owner doing $1M+ and feeling stuck, wanting to grow to $3M, $5M, or $10M but overwhelmed by marketing and operations

→ Tired of inconsistent lead flow, manual follow-up, and unpredictable results and ready to grow with smarter systems (Aka AI) 

→ You’re building a firm meant to last but you’re stuck doing everything yourself, stretched thin, and wondering how to scale without burning out or losing control

DM me if you’re ready to grow faster, lead smarter, or explore what’s next.

Most business brokers shouldn’t be selling companies
They should still be selling houses

The problem with most business brokers? 
They come from sales, banking, or real estate.

And that’s exactly why the industry’s broken.

We spoke with a business broker last week who’s been in the game for 10 plus years. 

He sighed and said,
“You know what’s wild? Most brokers out here used to sell houses or loans. And now they’re selling people’s lives’ work.”

Let that sink in.

These brokers aren’t operators. 
They’re closers. 

Trained to push deals through, not protect clients.

They don’t care if it’s a good fit. 
They care if it 𝘤𝘭𝘰𝘴𝘦𝘴.

And in professional services, CPA firms, law firms, advisory firms, that mindset is poison.

Because this isn’t a transaction. It’s a transition.

You’re not selling a house. You’re selling a legacy.

He told me straight up:

“If you want ethical deals, you need brokers who are CPAs or lawyers, not salespeople.”

Why?

Because they actually get it.

→ They understand the 𝘣𝘶𝘴𝘪𝘯𝘦𝘴𝘴 𝘮𝘰𝘥𝘦𝘭, not just the balance sheet. 
→ They know 𝘸𝘩𝘢𝘵 𝘤𝘢𝘯’𝘵 𝘣𝘦 𝘥𝘪𝘴𝘤𝘭𝘰𝘴𝘦𝘥. 
→ They protect value instead of chasing volume.

They’re not dealmakers. 
They’re advisors.

Here’s the hard truth: Most CPA firm owners make the same mistake their brokers do.

They’re great technicians. But they never learned to think like operators.

Both sides are stuck in the same trap, brilliant at the work, blind to the business.

And that’s why so many great firms sell for pennies on the dollar.

Because the wrong broker doesn’t just cost you a deal. 
They cost you your legacy.

Growth Partner for CPA & CFO Firms ($1M-$3M+) | Scale to Exit-Ready | Built Growth Engines Driving 8×-10x ROI | X- Private Banker | Founder, Investor & Operator

$700K in revenue. 70% margins. 
10 years in business. Zero growth

I talked to a CPA firm owner. 

His wife runs a remote practice doing $700K a year. 

Great margins. 
Offshore team. 
Fully systematized delivery.

But the number hasn’t moved in a while. 

Why?

No marketing. No outbound. No system.

Everything comes through referrals. 

Some clients come in. 

Some churn. 

It washes out every year.

Sound familiar?

Here’s what I told him: Referrals are killing your growth.

They’re great for getting started. 

But they’re unpredictable. 
You can’t scale them. 
You can’t control them.

If you want to grow from $700K to $2M+, you need a predictable acquisition system:
→ Paid ads (Meta, Google) targeting a specific niche 
→ High-converting landing pages that educate and capture leads 
→ CRM automation that nurtures without manual follow-up 
→ A qualified appointment flow (10–15 per month, not 100 dead leads)

This isn’t theory. It’s execution. We've built this for firms across tax, CPA, CFO and advisory:
→ 242 leads in 60 days at $17.89 CPL (CPA firm) 
→ 147 qualified calls at $188 CPL, closed 12 clients, $200K in fees (investment bank)

The system works. 

But most owners never build it, until they want to exit. 

Then they realize they built a practice, not a business.

If you’ve been at the same revenue for 3+ years… what’s the #1 thing holding you back? Let’s break it.

Most CPA firms hit $700K… and never grow again

Here's why.

I had a call with a firm owner last week. 

Smart guy. Great margins. 

His wife runs the day-to-day. 

They’ve been at $700K in revenue for a decade.

Not because they 𝘤𝘢𝘯’𝘵 grow. Because they never 𝘵𝘳𝘪𝘦𝘥 to.

No marketing. 
Barely a website. 
Just inbound referrals and word-of-mouth.

And here’s the thing:

That’s most CPA firms.

They’re comfortable. 
The lifestyle is manageable. 
So they never built a growth engine.

But here’s the problem when you stay in that zone too long:
→ You become dependent on referrals (unpredictable) 
→ You can’t forecast revenue (no control) 
→ You’re not acquisition-ready (buyers won’t pay a premium)

The gap between a $700K lifestyle practice and a $2M+ exit-ready business is massive. 

Most owners don’t realize it until they try to sell.

If you’re stuck in the comfort zone, ask yourself:
• Can I turn client acquisition on and off at will? 
• Can I predict next quarter’s revenue within 10%? 
• Would a buyer pay 3-5x for this today?

If the answer is no, it’s not the market. 

You just haven’t built the system yet.
