One of the first business books I ever read was Who Moved My Cheese? by Spencer Johnson. It is a short book, but its message has stayed relevant throughout more than two decades of running a physical therapy practice.
The core lesson is simple: change is inevitable, but how quickly you recognize and respond to it can determine what happens next.
That matters more than ever for private practice owners because the way patients find, evaluate, and choose healthcare providers continues to evolve.
The Problem: We Get Comfortable With What Works
In Who Moved My Cheese?, four characters search a maze for cheese, which represents the things we value and depend on.
Sniff detects change early. Scurry quickly takes action. Hem resists change and wants things to remain the way they were. Haw initially resists too, but eventually overcomes his fear and begins looking for new opportunities.
The danger for business owners is becoming like Hem.
A referral source works, so we assume it will continue working. A marketing channel produces patients, so we expect it to keep producing patients. A strategy succeeds for years, so we become reluctant to question it.
But the cheese eventually moves.
Six Lessons for PT Practice Owners
There are six lessons from the book that apply directly to private practice.
First, change happens. Permanent stability is unrealistic.
Second, anticipate change. Look closely at what is happening around your practice instead of waiting for a crisis.
Third, monitor change. Your KPIs, new-patient numbers, referral patterns, and marketing results often reveal small shifts before they become major problems.
Fourth, adapt quickly. The sooner you release an outdated strategy, the sooner you can find something that works better.
Fifth, move beyond fear. The disruption we imagine is frequently worse than what actually happens when we take action.
Finally, learn to enjoy the change. New conditions create new opportunities.
How This Played Out in a Real PT Practice
When I opened my practice in 2003, I needed roughly five new patients per week.
Initially, physician referrals were incredibly important. After losing a major referral source, we expanded aggressively and eventually built relationships with a much wider group of physicians. By 2008, one location reached 154 physician referrals in a single month.
Then healthcare changed.
Hospital systems began acquiring physician practices, and some physicians who previously referred to us could no longer do so freely. Once again, the cheese had moved.
We began developing additional direct-to-consumer marketing channels.
Then another important change appeared.
Around 2011, I was running Google Ads and listening to recordings of incoming calls. Two of the first three calls I reviewed came from referral coordinators in physician offices located less than half a mile from our clinic.
They already knew us.
So why were they searching Google?
I asked them.
Instead of simply choosing a clinic from a referral sheet, they were Googling a patient’s condition along with terms such as physical therapy near them.
That insight changed our strategy.
We doubled down on Google Ads, organic search, and condition-specific content so that when patients or referral coordinators searched for physical therapy, we appeared near the top.
Recognizing that behavioral shift early created a meaningful marketplace advantage.
The Cheese Is Moving Again
Today, another major shift is occurring.
Patients are increasingly using tools such as ChatGPT and Google Gemini to research conditions, treatments, and healthcare providers.
That means traditional SEO is no longer the entire game.
Practices now need to think about SEO alongside emerging areas such as GEO—Generative Engine Optimization—and AEO—Answer Engine Optimization.
We are already auditing our own visibility across the conditions, services, and treatments we want patients to find us for and identifying gaps before they become bigger problems.
The goal isn’t to abandon everything that worked before.
It’s to recognize when patient behavior is changing and adapt while the opportunity is still developing.
Conclusion
Your practice’s cheese will move.
Referral relationships will change. Marketing platforms will change. Search behavior will change. Technology will change.
The question is whether you notice those changes while they are happening—or after your new-patient pipeline begins to disappear.
Take a look at how patients are finding your practice today. Monitor the data, test the emerging channels, and don’t assume yesterday’s growth strategy will automatically produce tomorrow’s patients.
The practices that keep smelling the cheese are much more likely to find the next opportunity.
