Trusted Dental Practice Transition Advisors on the Seacoast

For dentists in Portsmouth and the wider Seacoast region, deciding when and how to transition a practice is rarely simple.

Every transition is different, so we tailor our approach to your goals, your timeline, and your practice, rather than running you through a one-size-fits-all process.

Seller Benefits of Working with Rosen Dental Transitions

Own a Dental Practice in Portsmouth

Buying a practice is different from starting one from scratch, you’re stepping into an existing patient base, an existing team, and existing systems, and the right fit matters as much as the right price. Rosen Dental Transitions works with dentists across Portsmouth and the Seacoast to find practices that actually match what they’re looking for, then walks alongside them through financing, diligence, and closing.

How a Rosen Dental Transition Works From Start to Finish

We built our process around one goal: no matter which side of the transaction you’re on, you should always know what’s happening next and why.

We start by listening – to your timeline, your priorities, and what a successful outcome looks like for you specifically, whether you’re preparing to sell or exploring ownership for the first time.
We dig into the financials and operational data behind a practice to arrive at a realistic, defensible value, not just a rough estimate.
For sellers, this means putting your practice in front of our existing network of qualified buyers. For buyers, it means surfacing opportunities you wouldn’t have found searching public listings on your own.
We take on the back-and-forth of offers and counteroffers directly, so you’re not negotiating your own deal while also running your practice.
We manage the final details and transition logistics so the handoff – of patients, staff, and operations – goes smoothly on both sides.

How is my dental practice's value actually determined?

There’s no single formula, it comes down to your financials, how your practice is run day to day, what services you offer, and who your patients are, weighed against what buyers are actually paying for practices like yours in the Portsmouth area right now. Sometimes that means listing above the “paper” value; sometimes it means adjusting down to match real buyer demand. If you’re curious about where your practice stands today, even without a firm plan to sell, our Simulated Sale program can walk you through it.
Most sales run 6 to 9 months from signed contract to closing, assuming normal buyer interest. That said, timelines shift depending on things like your practice’s location, the makeup of your patient base, whether an associate is already positioned to buy in, and whether DSOs are actively interested. We’ll give you a straighter answer once we understand your specific situation.
Not through us. Everyone who gets a look at your practice’s financials or details signs an NDA first, no exceptions. We also help manage exactly when and how your staff and patients hear about the transition, so you stay in control of that timing.
The buyer ultimately makes staffing calls, but a strong, established team is genuinely valuable to them – most buyers want to keep good people, not replace them. That’s a big part of why we involve you in choosing the buyer in the first place: the better the fit between your team and the incoming owner, the better retention tends to be.
Three things matter most: whether the cash flow holds up after you account for debt service, whether the clinical services offered match what you’re actually equipped to provide, and whether the business and local market support where you want to take the practice long-term. Beyond that, look closely at the patient demographics and growth trajectory. We help buyers stress-test opportunities against all of this before they commit.
Yes! This is a big part of what we do. We work regularly with lenders who specialize in dental practice acquisitions specifically, which tends to get buyers better terms than a general business loan would. We’ll walk you through your options and make the right introductions based on your situation.
