Almost every practice sale now includes a period during which the seller keeps working. Buyers require it because production tends to follow the dentist rather than the address, and sellers accept it because a portion of the price usually depends on it.
The arrangement is common enough that its failure modes are well documented, at least anecdotally. What is less discussed is how early the outcome gets decided.
The first quarter is the whole thing
Sellers who describe the transition as having gone well and sellers who describe it as having gone badly agree on the timeline. By ninety days, the staff know whether the seller still has authority, and once they know, the answer is very difficult to revise.
The mechanism is mundane. A staff member brings a scheduling question to the former owner out of habit. The former owner either answers it or redirects it. Whichever happens in the first few weeks becomes the pattern, and the pattern determines whether the seller spends the next three years as a clinician or as a shadow manager with no actual authority and full historical responsibility.
Nobody lied to me. I understood the contract. What I did not understand was that I would keep having opinions.
The three failure modes
The first is the seller who cannot stop deciding. Every redirected question comes back through them, the new ownership’s changes get quietly reversed, and the relationship degrades over eighteen months into something both parties describe with visible fatigue.
The second is the seller who disappears entirely — stops attending meetings, stops explaining why things were built the way they were, and leaves the buyer to rediscover by failure a set of decisions that had reasons.
The third is subtler and the most common: the seller stays, cooperates, and slowly discovers that the practice they built is being operated in a way they would not have chosen. Nothing is being done wrong. It is simply no longer theirs, which is the entire point of the transaction and is nonetheless harder than nearly every seller expects.
Dr. Omar Haddad sold to a group in 2019 and spent eighteen months in that third category. “Nobody lied to me,” he says. “I understood the contract. What I did not understand was that I would keep having opinions.”
What the successful transitions did
Two things, consistently.
They defined authority explicitly and in writing before closing — not the seller’s role, which every agreement covers, but specifically which decisions the seller still makes and which they do not, named individually. Sellers described this conversation as unpleasant and unanimously worth having.
And they set an end date for the seller’s involvement that both parties actually believed. Open-ended arrangements, or ones that everyone privately expected to be extended, produced the worst outcomes in almost every account we heard.
The transition period is not a way of easing out of ownership. It is a job with different terms, and the sellers who treated it that way from the first week are the ones who finished it on good terms.
