What Twenty-Five Years in Medicine Taught Me About Building Businesses
The habits that keep patients safe, from preparation to teamwork to honest follow-up, are the same habits that build durable companies.

The most useful business training I ever received happened in hospitals. After more than twenty-five years in medicine, much of it as an interventional cardiologist, I have found that the habits that keep patients safe are the same habits that build companies that last: preparation, clear roles, honest measurement and the discipline to follow up.
That is not a claim that physicians make natural executives. Some instincts medicine rewards, such as personal responsibility for every detail, reluctance to delegate and comfort with very long hours, can work against a growing business. But several lessons from clinical practice translate almost directly, and they have shaped how I have built as a physician entrepreneur across healthcare, medico-legal advisory, aerospace testing and long-term investment.
The checklist is not bureaucracy
In a cath lab, nobody begins a procedure on memory and goodwill. The patient, the plan, the equipment, the contingencies and each person’s role are confirmed before the first step. From the outside it can look like ritual. It exists because skilled people under pressure still forget things, and the cost of forgetting is high.
Businesses usually fail the same way: not from one dramatic error but from small, predictable omissions. A contract term nobody re-read, a renewal date that slipped, a cash need that was visible weeks earlier. The remedy is the same as in the lab. Write down what must be true before a decision is made, and check it every time.
Teams matter more than individual brilliance
Modern cardiology is a team discipline. The result of a procedure depends on nurses, technologists, referring physicians and the people who schedule, document and follow up. A brilliant operator in a poorly run lab tends to do worse than a good operator in a well-run one.
In business I have learned to spend more time on who is in the room than on any single plan. A company with the right people and clear responsibilities can survive a weak strategy and correct it. The reverse is rarely true.
Measure what actually matters
Medicine has long experience with measurements that look reassuring and mislead: a number improves while the patient does not. Good clinicians learn to ask which measures truly track the outcome they care about.
Companies have their own versions: revenue that grows while margins shrink, activity that rises while customers quietly leave. Before tracking anything, I want to know what result we are trying to produce over years rather than quarters, and which few numbers will tell us honestly whether we are getting there.
Respect the downside
Every intervention carries risk, and the best physicians never forget it. They take on difficult cases, but they prepare for complications and they know when not to proceed. That way of thinking applies as much to a new venture as to a procedure. In practice it means sizing commitments so that a bad outcome is survivable, keeping reserves, and agreeing in advance what would make us stop.
Follow-up is where the value is
A procedure is a moment; a patient’s health is a long relationship. The same is true of a company. Most of the value in a business is created not at its founding or its acquisition but in years of steady, unglamorous follow-through: reviewing results, correcting course and keeping promises to customers and partners. That conviction is why I value continuity in medicine, and why Impero Capital Holdings is built around long-term ownership rather than quick turns.
What medicine does not teach
Medicine did not teach me how to read a balance sheet, negotiate a lease or hire well outside my own field. I learned those from experienced advisers, from mistakes and from asking basic questions without embarrassment. Perhaps the most valuable habit medicine did give me is the expectation of lifelong learning. Every year in practice brings new evidence, new devices and new guidelines, and the physician who stops learning falls behind. Business is no different.
The common thread
Building a business and caring for patients are different kinds of work. Both, however, reward the same temperament: careful preparation, respect for the team, honest measurement, a clear view of risk and patience over the long term. After twenty-five years, that is the part of medicine I carry into everything else.
