A Worked Example

What coordination is actually worth.

Before a hard cancer case is treated, the most important decision isn't made by a single doctor. It's made by a room. Surgeons, oncologists, radiologists, and pathologists review the same patient together, because every recommendation changes the others. Complex wealth deserves the same operating model. Here is what it looks like when the pieces of a financial life are run together, and what it quietly costs when they aren't.

Why coordination, not just expertise

The fields that stake lives on this figured it out long ago.

Coordination isn't a soft skill or a nicety. In the places where the cost of a missed hand-off is measured in lives, the coordinating function is the system. Wealth borrowed the specialists but forgot the room they're supposed to meet in.

Medicine
The tumor board

The board decides before anyone acts — and one person stays accountable for the whole patient, not a single organ. That's the attending physician.

Aviation
Crew resource management

Crash rates didn't fall because pilots got more talented. They fell when the industry required structured cross-checking between captain, first officer, and the ground. Coordination itself became the safety system. Great individuals, in silos, still crash.

Construction
The general contractor

Nobody lets the architect, the structural engineer, the electrician, and the plumber build a house on their own schedules. You hire a general contractor. Not because they're the best electrician, but because one person is accountable for the whole project, in the right order.

Your CPA, your attorney, your insurance agent, your banker: each is a gifted specialist. In most financial lives, almost no one is the attending.

IThe missing role

Meet the Harris family. Their balance sheet is not unusual for a successful household: a business, a couple of homes, a concentrated equity position, retirement accounts of every flavor, a life insurance policy. Real, hard-won, and spread across a half-dozen specialists.

Life insuranceDeath benefit, personally owned$2,000,000
Estate at deathEverything above, untouched$8,000,000

Now one question. Who wakes up every morning responsible for how all of these interact?

Usually, no one. The CPA owns the tax return. The attorney owns the documents. The insurance agent owns the policy. Even the investment advisor usually owns only the portfolio. Each is excellent inside their own lane. The space between the lanes, where most of the money is quietly won or lost, belongs to no one.

How all of them interact

That space is the product. Institutions have a name for filling it. They call it an operating framework, and it is why every important decision at a large institution is made in the context of every other one. Driftwood brings that operating model to a single household.

IIOne move is never one move

The reason a household needs an attending is simple: no financial decision stays in its own lane. Pick a move below and watch which parts of the system it actually touches. Every one of them is a place a decision can be made well, or made in isolation and paid for later.

IIIWhich systems each decision touches

Coordination — the product itself — set as an engineer would set it: a dependency structure matrix, not a chord diagram. Decisions down the side, systems across the top; a filled mark is a primary effect, a hairline mark a secondary one. Rest on any mark and the specific consequence is stated in words below.

IVThe $600,000 conversation nobody had

Now draw a state line through the Harrises' balance sheet. Same people, the same $8 million, the same specialists all doing good work. The only variable is where they live, and it changes almost everything.

If they live in · Illinois

The estate-tax trap

4.95% flat income tax · $4,000,000 estate exemption. Not portable, not indexed, and it taxes the whole estate once you cross it.

Uncoordinated
  • The $2M policy is owned personally, so the death benefit sits inside a taxed estate. The money meant to create liquidity is inflating the bill.
  • The business and land are frozen; their future growth compounds inside the estate.
  • Illinois estate tax on $8.0M: $680,634, due nine months after death, with no buyer for the business and no cash to pay it.
Coordinated
  • Move the policy into an ILIT. The $2M death benefit leaves the estate and becomes the liquidity that pays the tax.
  • Fund the premium through the business with a §162 bonus, not after-tax dollars.
  • Gift discounted business interests to a grantor trust over time; hold low-basis assets for the step-up instead of gifting them away.
Illinois estate tax
≈ $395,000

saved, and the business survives intact.

$680,634 on an $8.0M estate  →  $285,714 on a coordinated $5.0M estate.

If they live in · Texas

The income-tax opening

No state income tax · no state estate tax. Federal exemption is $15M, so this estate owes $0 in estate tax, state or federal.

The leak moves
  • The estate problem vanishes at the border. So the value of coordination moves to income tax and timing, where it's easy to leave money on the table.
  • Uncoordinated, the $1.4M of pre-tax accounts grows into forced RMDs and a fully-taxable inheritance for the kids.
Coordinated
  • Convert to Roth aggressively. With no state tax, each conversion costs only federal, and the balance grows tax-free, dodges RMDs, and passes to heirs income-tax-free.
  • Time the business sale and RSU unwind to fill federal brackets without tripping the 3.8% surtax. There is no state layer to fight.
  • Locate assets for the federal step-up; coordinate the HSA beneficiary so it isn't taxed to the next generation.
State estate tax
$0

and that's exactly the point. The prize here is a lifetime of tax-free Roth growth and well-timed events: six figures that never show up as a tax bill.

~$69,000 of state tax avoided on the Roth conversions alone, before decades of tax-free compounding.

Same family. Same $8 million. In Illinois the first coordinated move is worth roughly $395,000; in Texas the same family's biggest opportunity is a lifetime of tax-free growth it would otherwise miss.

The dollar figures change at every state line, in every bracket, in every year. The discipline that captures them does not. That discipline is the product.

Illustrative and educational — not investment, tax, or legal advice. This is a hypothetical household; figures depend entirely on your own holdings, basis, bracket, and state, and on tax law as it stands. Illinois estate-tax amounts reflect the state's graduated schedule at a $4,000,000 exclusion; the federal estate & gift exemption is $15,000,000 per person for 2026. Strategies such as ILITs, grantor trusts, §162 bonus arrangements, and Roth conversions carry their own rules, trade-offs, and risks, and should be confirmed with your tax and legal advisors under current law.
