Dental Partnership Buy-In: Build It With the Divorce in Mind

| August 26, 2026

Here is the sentence that has killed more dental partnerships than any bad contract ever written: “We’re basically family, we’ll figure out the details later.”

No, you won’t. You’ll figure out the details in a deposition. A dental partnership is a business marriage — and the ones that survive are built by people sober enough to plan the divorce on day one. That is not cynicism. That is the single most protective thing you can do for the friendship, the practice, and your net worth.

If you’re an owner thinking about bringing on a partner, or an associate being dangled the carrot of “someday equity,” this is the conversation nobody has honestly with you. So we’re going to have it.

Why do most dental partnerships blow up?

They don’t blow up over money. They blow up over unspoken expectations about money, effort, and power — expectations nobody wrote down because writing them down felt like an insult.

On the Bulletproof Dental Practice Podcast, a guest who merged six practices into one partnership put it perfectly, and Craig Spodak finished the thought for him: “Build it with the divorce in mind.” His exact words on going into any merger: “You’ve got to go in eyes wide open… look at it as almost like the divorce is imminent. Have everything outlined as to what could go wrong on the front end.”

That is the whole game. The agreement isn’t there for the good years when you’re high-fiving over record collections. It exists for the year one of you gets divorced, gets sick, wants to slow down, or decides they hate the other’s guts. If the document only works when everyone’s happy, it’s not a document — it’s a hope.

How do you actually value a partnership buy-in?

This is where 90% of deals stall, usually because someone gives fatally bad advice: “You have to pay off your practice debt before you bring on a partner.” That advice is wrong, and Pete Boulden’s take is blunt — an advisor who says it doesn’t understand partnership valuations and should be replaced.

Debt doesn’t prevent a partnership. It adjusts the price. Here’s the real math, the same corporate-finance methodology law firms, accounting firms, and private equity use every single day:

• Step 1 — Adjusted EBITDA: Current EBITDA + annual debt service. This shows what the practice truly earns as if it had no debt.
• Step 2 — Enterprise Value: Adjusted EBITDA × industry multiple. Dental practices typically trade at 5–7x EBITDA depending on size, profitability, location, and specialty mix.
• Step 3 — Equity Value: Enterprise Value − Total Debt + Cash. Debt reduces what the equity is worth. The partner buys equity, not the enterprise.
• Step 4 — Purchase Price: Equity Value × Ownership %. And separately, the partner assumes Total Debt × Ownership % in debt responsibility.

Can you show me the numbers on a real deal?

Take a practice earning $500K EBITDA after debt payments, with $100K in annual debt service, $800K of outstanding debt, and $50K cash. An associate is buying in for 25%.

• Adjusted EBITDA: $500K + $100K = $600K
• Enterprise Value (at 6x): $600K × 6 = $3.6M
• Equity Value: $3.6M − $800K + $50K = $2.85M
• Partner purchase price: $2.85M × 25% = $712,500
• Partner debt responsibility: $800K × 25% = $200,000

The panicked owner hears “$712,500 plus $200,000 — you’re making them pay twice!” Wrong. Look at the alternative. If the practice were debt-free, that same 25% would cost $900,000, with roughly $105K/year in debt service. In the debt-carrying deal, the partner borrows less ($712.5K → ~$83K/year) and their share of practice debt adds ~$25K/year — about $108K total. The difference is negligible, and the partner pays less cash up front.

Here’s the kicker most advisors miss: under IRC Section 752, the debt the partner assumes gets added to their tax basis. Cash contributed ($712,500) + debt allocated ($200,000) = $912,500 of basis. Higher basis means more tax-free distributions and a lower taxable gain when they eventually sell. Assuming debt is actually tax-advantageous.

What has to be in the partnership agreement — in ink?

If it’s not written down, it doesn’t exist. These are the clauses that separate partnerships that last from partnerships that litigate:

• Valuation methodology — not just today’s number, but the exact formula used to value shares in the future (adjusted EBITDA × agreed multiple, minus debt). Fights happen when the buy-in method and the buy-out method don’t match.
• Debt allocation & service — who’s responsible for what percentage, and that debt service is paid from operating cash flow before profit distributions.
• The buy-sell (divorce) clause — what triggers a forced sale (death, disability, withdrawal, termination), how shares are valued at exit, and the payment terms. This is the divorce plan Craig was talking about.
• Decision rights & deadlocks — what needs unanimous consent, what a majority decides, and how you break a 50/50 tie before it breaks you.
• Roles, hours, and production expectations — the “we’ll both just work hard” handshake is where resentment is born. Define it.
• Non-compete and restrictive covenants — so a departing partner can’t open across the street and take the team.

One more non-negotiable from the corpus: review your existing loan agreements before you finalize anything. Lenders often have change-of-ownership covenants that can blow up a deal you thought was done.

Why do a partnership at all?

Because dentistry is a lonely profession, and the drill-fill-bill treadmill is a slow way to burn out alone. Done right, a partner is retention insurance for your best associate, a succession plan that doesn’t require selling to a DSO, and — this is the part Craig won’t let us forget — someone in the trench with you who actually cares whether you make it.

That’s the whole Bulletproof thesis. Clinical excellence is the floor. A life you actually want is the goal. And the fastest way to get there is to stop building alone.

Where do you go from here?

Get the deal structure right and a partnership can be the best decision of your career. Get it wrong and it’s the most expensive divorce you’ll ever pay for. The difference is a room full of people who’ve already done it, and the frameworks to do it in ink.

Start with the show: the Bulletproof Dental Practice Podcast is where Pete and Craig break down the deals, the disasters, and the systems in plain English. When you’re ready to build with people who’ve structured these agreements — and lived through them — that’s what the Bulletproof Mastermind exists for. And once a year, the whole tribe gets in one room at the Bulletproof Summit.
