Real results. Real practices. Real numbers.
We get this question all the time: how much do practices actually grow when they work with you? It's the right question — and one we've always struggled to answer publicly, because the honest answer lives in our clients' financials. Asking people to share their income with the internet felt like too much. So we found a middle ground: below are real situations from real clients, every number pulled directly from their books. Names and likenesses have been changed to protect the successful.
Results vary. These are real results from real GreenOak clients, but they aren’t typical of every practice we work with. Each outcome depends on the practice’s starting point, size and market, and on how fully the owner acts on the data and guidance. Working with GreenOak doesn’t guarantee any specific result.
Revenue & Profitability Case Study
WHEN REVENUE ISN'T THE PROBLEM — PROFITABILITY IS.
This wasn't a revenue problem — it was a profitability problem. With a team of 20, half part-time, and too many clients on sliding scale, the practice was busy but not building anything. Through CFO services, they restructured expectations for full-time clinicians, added a bonus system tied to clinical hours, tightened sliding scale policies, and got serious about tax planning and cash reserves. The numbers followed.
“GreenOak has helped us develop and implement our financial goals and taken us from a 1% profit business to almost 10% and growing profitable business." — Practice owner

Group Growth Case Studies
GROUP PRACTICE GROWTH
Practice Owner, Mid-Atlantic | 9 Clinicians, 1 Location
Duration: Over 2 Years
More than tripled revenue in two years. Net income grew from $28K to $158K.
Revenue growth: +222% | Net income growth: +463%
Profit margin, year 1: 13% | Profit margin, year 2: 22%
This owner grew fast — but not recklessly. As the clinical team expanded, they were intentional about building the administrative support to match. A part-time admin came on first, handling scheduling and paperwork while the owner stayed focused on clients and growth. By the time the team hit nine clinicians, the admin role had grown to full-time — and the owner had successfully moved the operational weight off their own plate without it showing up as a margin problem. We helped them see at each stage what the numbers could support, so every hire felt like a decision rather than a gamble.
Practice Owner, South | 10 Clinicians, 1 Location
Duration: Over 2 Years Clinicians: Grew from 3 to 10
Crossed $1M in revenue while growing net income from $65K to nearly $300K — and more than doubled their profit margin.
Revenue growth: +91% | Net income growth: +356%
Profit margin, year 1: 9% | Profit margin, year 2: 24%
This owner kept their administrative costs remarkably lean throughout the growth — not by doing everything themselves, but by being smart about how the work got done. Tech tools, automation, and systems that reduced manual admin burden meant they could scale the clinical team without scaling overhead at the same rate. Getting clinician compensation structured correctly from the start meant every new provider added to the bottom line rather than diluting it. We provided the financial benchmarks and monthly reporting to make those decisions with confidence rather than guesswork.
Practice Owner, Southwest | 8 Clinicians, 2 Locations
Duration: Over 2 Years Clinicians: Grew from 3 to 8
Crossed the million-dollar mark. Net income grew 142% over two years.
Revenue, year 1: $487K | Revenue, year 2: $1.03M
Net income, year 1: $108K | Net income, year 2: $261K
This owner had been eyeing a second location for a while — but didn't move until the first one was truly ready. For a full year, they saved deliberately toward the expansion, building up cash reserves while we tracked exactly what the second location would need to be viable from day one. When they finally signed the lease, it wasn't a leap of faith — it was a fully planned financial decision with a clear runway. They crossed the million-dollar mark in the process, and have just upgraded to CFO Services. They're just getting started.
Practice Owner, Midwest | 45 Clinicians, 2 Offices + Virtual Team
Duration: Over 3 Years Clinicians: Grew from 26 to 45
Added $418K in net income — more than doubling profitability on a practice already doing $2.5M.
Revenue, year 1: $2.53M | Revenue, year 3: $3.91M
Net income, year 1: $386K | Net income, year 3: $803K
When you're already running a $2.5M practice, growth creates a new problem: a tax bill that grows with it. This owner had the foresight — and the CFO partnership — to get ahead of it. Proactive tax planning meant the bill was never a surprise, and the savings were reinvested into the expansion rather than handed over unnecessarily. Expanding from 26 to 45 clinicians across two locations and a virtual team required disciplined thinking about compensation structures and expense management at every stage. We helped keep the numbers honest so every decision was grounded in data rather than gut feel.
Practice Owner, West Coast | 38 Clinicians, 2 Locations
Duration: Over 2 Years Clinicians: Grew from 22 to 38
Nearly tripled revenue in two years. Net income up more than 4×.
Revenue, year 1: $1.16M | Revenue, year 2: $3.20M
Net income, year 1: $121K | Net income, year 2: $519K
At 22 clinicians, this owner knew they were approaching the ceiling of what they could personally oversee. The question wasn't whether to hire a Clinical Director — it was when, and what they could actually afford. We worked through the numbers together: what the role would cost fully loaded, what revenue threshold made it sustainable, and what the practice needed to look like before adding that level of overhead. When they pulled the trigger, it was with complete financial clarity. The Clinical Director came on, the owner stepped back from day-to-day clinical oversight, and the practice accelerated. Net income grew more than 4× in two years.

Strategy Case Study
STRATEGIC MOVES THAT CHANGED EVERYTHING
Practice Owner, Pacific Northwest
Duration: Client since 2019
Six years of steady growth — then an S Corp election saved her ~$7K in taxes in year one alone.
Revenue, 2019: $107k
Revenue, 2025: $189k
SE tax savings: ~$7K in year of election, 2024
This client has no interest in building a group. She just wants to practice well and keep more of what she earns — and that's a completely valid goal. This practice owner was always fully booked, the problem was never demand.
As a solo practitioner, sole breadwinner, and mom of two, there were simply no more hours in the day. So we focused on making every hour count: holding her accountable to raising her cash pay rate every year (often pushing her toward a bigger increase than felt comfortable), and systematically dropping low-paying insurance panels.
She also runs one of the leanest practices we work with — minimal overhead, no waste. The S Corp election in 2024 was the natural next move: a structural change that kept more of what she'd already earned.

ALL ABOUT TAXES STORIES
Sally
With the complexity of running an S Corporation in NYC—including extra filings and city-level fees—we helped Sally proactively plan her transition from group to solo practice. Our team guided her through revoking her S Corp election at the right time, simplifying her tax filing to a Schedule C and avoiding unnecessary administrative burdens.
Ray
Ray shared that working with GreenOak was easy and seamless. With both his accounting and tax services under one roof, we helped him make a smooth transition to an S Corporation structure—unlocking meaningful tax savings for the future and setting him up for long-term financial success.
David
For clients doing business across state lines, having accounting and tax services in one place is a game-changer. David’s practice operates in 4 states, increasing the complexity of his annual tax filing.
Our tax and accounting teams work hand-in hand to handle complex state apportionment issues for David—saving him from playing middleman and avoiding costly errors that can happen when coordination falls through. It’s just one of the ways we make taxes less stressful and more accurate.
Dolly
When Dolly came to GreenOak in 2022, we discovered the IRS had her listed as a C Corporation due to a misfiled S Corp election by a previous accountant. We quickly stepped in, submitted a late S Corporation election, and successfully got her 2021 and 2022 tax returns processed. In 2025, we secured first-time penalty abatement for the late filing. Dolly has been deeply appreciative of our persistence in cleaning up the mess—and getting her back on track.
Stephanie
With both accounting and tax under one roof, Stephanie benefits from a seamless year-end strategy. Each year, she collaborates with our team to calculate her annual bonus amount with precision—incorporating expert guidance from her trusted financial planner. It’s strategic, proactive, and stress-free.
A note on who deserves the credit.
These numbers represent real transformation — but the owners behind them are the ones who showed up every day and did the hard work.
They made the difficult decisions, had the hard conversations, and stayed the course when it wasn't easy. That's true of their practices, and it mirrors what they know from their own work with clients: insight and support can open doors, but the client has to walk through them.
The same is true here. Every result on this page belongs to an owner who engaged — who looked at the numbers, asked the hard questions, and actually acted on what they learned.
We don't have a magic wand, and handing us your books doesn't automatically fix what's underneath them.
What we can offer is the data, the guidance, and someone in your corner when the big financial decisions land on your desk. But the deciding?
That part is always yours. Knowing your numbers — really knowing them — changes how you lead. And having a team that knows your numbers as well as you do, and will tell you the truth about them? That part turns out to be priceless.
