Crestbourne is an independent, fee-only fiduciary. We manage portfolios, estates and family offices for families who intend to still be here in fifty years.
The horizon we plan against — 1974 → 2044Three generations · seven market cycles
Most families arrive with an investment problem and discover it was an estate problem, or a tax problem, or a family-communication problem. We staff all four so nobody has to coordinate their own advisers.
Each discipline in fullGlobally diversified, low-turnover portfolios built around your actual liabilities — school fees, a business sale, a fifty-year endowment — not a risk questionnaire.
Structures that survive the people who wrote them. We draft with your attorney, fund the trusts properly, and revisit them when the law or the family changes.
Tax is the largest expense most families will ever carry. We plan for it across the decade, not in the last week of December.
For families whose affairs have outgrown a single adviser: consolidated reporting, bill pay, next-generation education, and a governance forum that keeps everyone speaking.
A long horizon is not a slogan — it is a constraint we accept. It means we will decline to chase the year's best-performing asset class, and it means we will look wrong for stretches. We think that is the price of being right over thirty years.
Our portfolios turn over roughly 8% a year. We rebalance on rules, not on conviction. And we tell you, in writing, what would have to be true for us to change our minds.
Read our investment policyThis is the arc of an actual Crestbourne relationship — anonymised, and typical. The work changes at every handover. The mandate does not.
A manufacturing business, one illiquid balance sheet, and no plan beyond the next order book. We began where we always begin: a liquidity plan, and a will.
The company sold. Overnight, an operating family became an investing family — a harder transition than it sounds. We built the first portfolio and the first trust.
Four households, three countries, one shared portfolio and diverging views. We stood up a family council, wrote a constitution, and separated the money that must stay from the money that may go.
Children who are not yet adults will inherit the decisions we are making this year. That is the discipline the entire firm is organised around.
“My father chose Crestbourne. I kept them because they told me, plainly, when I was about to do something foolish — and because they say the same thing to my daughter now.”Client, second generationRelationship since 1998
We are legally bound to act in your interest — and we put that duty in the engagement letter, not the footnotes.
One transparent fee on assets we manage. We are paid by you and by nobody else — no product, no platform, no referral.
0.85% to $5M · 0.65% to $20M · 0.45% thereafter. Family-office mandates are quoted as a flat annual retainer.
Your assets are held at a third-party custodian in your name. We can trade them. We can never withdraw them.

We do not publish client names or balances. What we can describe is the shape of the problem and what changed.
Liquidity event
We built a staged unwind with a collar, pre-funded the tax, and moved a slice into a charitable trust before the sale — so the gift went out at a low basis rather than a high tax bill.

Family governance
The money was never the problem. We separated the shared endowment from individual accounts, chaired the first three family meetings, and wrote the decision rules everyone signed.

Succession
She did not. A prior adviser had never funded the trust that existed on paper. We valued the estate properly, elected instalment relief, and the land stayed with the family.

Quarterly letters and occasional notes. No market calls, no forecasts we cannot keep.
An hour with a partner. Bring the question that has been sitting unanswered — the sale, the trust, the child who is about to inherit. We will tell you plainly whether we are the right firm, and if we are not, who is.
