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.
Case Study One: Revenue & Profitability
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.

Case Study Six: Strategy
STRATEGIC MOVES THAT CHANGED EVERYTHING
Practice Owner, Pacific Northwest
Package: Solo
Duration: Client since 2019
Six years of steady growth — then an S Corp election saved her ~$18K 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.
A note on who deserves the credit.
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.
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.
