Building your wealth was just the beginning

Clarity for what comes next.
The full picture aligned.
Stability across generations.

Your wealth has reached a scale where the questions get harder, and the people you rely on for answers matter more than ever.

You're not just managing money. You're managing business obligations, family dynamics, charitable commitments, and the responsibility of deciding what your wealth becomes.

Arrowroot Family Office serves families whose financial world has outgrown conventional advice. We coordinate investments, tax, estate, philanthropy, and the operational work of a financial life that runs like an enterprise. We take in the full picture, see how it is all connected, and help you carry the weight of getting it right.

Everything your wealth touches, managed as one.

Running the whole picture

At this scale, the hardest problem is that everything is connected. We see the whole picture and simplify the complex so no decision is made in isolation.

We serve founders who have exited, families with generational wealth, and households whose financial life now runs like an enterprise.

Protecting wealth

For families with operating businesses, concentrated positions, and assets across multiple jurisdictions. The risks at this scale are quieter than they were on the way up, and the consequences of getting them wrong are larger.

We coordinate the structures, the coverage, and the documents so the wealth holds through tax events, transitions, and the things nobody plans for.

TAX STRATEGY
Coordination across every moving part

Tax decisions handled alongside estate structure and entity design, so a choice in one place does not create a problem in another.

EXPLORE
RISK MANAGEMENT
Coverage that matches the exposure

Property, liability, life, and umbrella structured for the scale of what you own, with the gaps most policies leave addressed before they matter.

EXPLORE
ESTATE PLANNING
Structures that hold across decades

Trust architecture, gifting strategy, and entity design built to carry intentions through generations and through the tax code as it changes.

EXPLORE

Preparing the next generation

The hardest part of generational wealth is not the structures. It is whether the people inheriting them are ready to make decisions with the weight that comes attached.

We work alongside families to build the readiness, the language, and the governance that lets the next generation step into responsibility on their own terms.

NEXT GENERATION PLANNING
Readiness before responsibility

Financial education, decision-making practice, and the conversations that prepare adult children for what comes with the wealth.

EXPLORE
FAMILY GOVERNANCE
The structures that hold the family together

Family councils, charters, and decision rights that turn shared wealth into a shared framework rather than a recurring conflict.

EXPLORE
FAMILY RETREATS
Time set aside to do the work

Facilitated gatherings where the family addresses the conversations that get postponed in the rhythm of everyday life.

EXPLORE

Defining your legacy

At some point, the question shifts from how the wealth grows to what it is for. Philanthropy, the businesses you built, the institutions you support, and the values that travel with the money all need their own architecture.

We help families turn intention into structure, so what the wealth stands for outlasts the person who built it.

Managing the human side

The hardest parts of wealth are rarely financial. We guide the emotional side directly, because it is often what determines whether a legacy survives the next generation.
