In Their Words
The Rockefeller Family Association Documents
Two decades of meeting minutes. One family's complete operating system. Between 1905 and 1925, the Rockefeller family convened annually, drafted minutes, elected officers, and published their proceedings as bound volumes.
These volumes were passed down to Mark L. Rockefeller, creator of The CenturyHouse Method.
What matters most is not the Rockefeller wealth (that was just one branch of a much larger family), but rather the intergenerational family legacy architecture: meetings, records, roles, rituals, responsibilities, and shared memory.
CenturyHouse translates that architecture - along with 25+ years of research and studies - into accessible digital tools so every family can build a lasting legacy.
Most successful families fail to pass their values along to their children.
Why CenturyHouse exists.
I spent over two decades studying and looking for a legacy framework that combined the rigor of a family office with the intergenerational convictions of a father. CenturyHouse is the result of that work. I built it for myself and others like me.
CenturyHouse is a system of simple, easy, and accessible digital tools across five integrated pillars that any family founder can install to give his or her family a structure designed to last 100-years.
The toolset for intergenerational continuity is no longer just for wealthy families. It is now accessible to anyone.
Every family can now experience the near-term clarity, guidance, comfort, and long-term peace of mind that a strong intergenerational family strategy provides.
Fully installed, CenturyHouse becomes the living repository of your family's 100-year strategy. I pray it benefits your family now and for generations.
We call it Family Entropy.
In physics, entropy is the tendency of systems toward disorder unless energy is intentionally applied to hold them together. Families are no different. Left unattended, every family drifts toward fragmentation over time.

Five Pillars. One operating system.
Each pillar is a layer of the system. Together they hold up the 100-year family.
Ensuring your children, grandchildren, and great-grandchildren know what your family represents.
Building your family its own Family Charter or Constitution for clean, long-term decision-making.
Tools for internal funding decisions that align family members and spending with your values.
Your family's story and traditions, preserved and carried on for generations.
Developing your children and grandchildren individually so the family thrives long-term.
Every tool, in one library.
Filter by pillar, sort by status, and open any tool. Your work saves as you go.
Delay is not neutral.
You already know this work matters. Here is why it cannot wait.
Family entropy compounds.
Every family drifts toward fragmentation unless energy is applied to hold it together. A family operating system is that energy.
What you do not intentionally install, something else will install for you.
The benefits begin immediately.
The compounding is generational. The relief is not. Families who install the system report change within the first season of use.
Where your family builds, and where it endures.
CenturyHouse becomes the living, central repository of your family's 100-year strategy and documents. You add, invite, and control access for family members and trusted advisors.
The Family Archive
- Charter, Legacy Letters, Chronicle, and family documents
- Stored permanently in your private family vault
- The multigenerational record, built to be inherited
A System That Replicates
- Built to be passed down, not stored and forgotten
- Heirs maintain and adapt what you built
- Each generation builds on your foundation
Invite your family
Bring your spouse and adult children onto the platform. You control which pillars each person sees, and whether they can comment or download.
Invite your advisors
Add your financial, legal, or trusted advisors with pillar-scoped review access. Advisors join free, with their own account.
Guidance from Mark, built in
As you move through each pillar, short notes and prompts from Mark meet you along the way, so you are never building alone.
An operating system. Not a coaching program.
CenturyHouse is built for successful men and women ready to build a family capable of carrying success into the future.
You built something.
More than your parents had. Now you ask whether it will survive you.
You lead your family.
You want them to inherit more than money.
You see the long-term.
You think and worry about the life your children and grandchildren will live.
You feel your family drifting.
Traditions fading. Family entropy, in real time.
You want a system, not a sermon.
You have the will. You need the structure.
You know this is on you.
The continuity of your family is yours to lead.
If you came for a quick fix, this is not it. If you came for a method that lasts, you are in the right place.
Build the family your great-grandchildren will inherit.
They can also be rebuilt family by family.
For any family that cares enough to try
You do not need a fortune to build a family that lasts.
The families that endure for a hundred years are not the ones with the most money. They are the ones with the clearest values, the strongest bonds, and a deliberate way of passing both to their children.
That is what a family operating system is. Not a trust. Not a foundation. Not a number on a statement. It is the small set of habits, words, and traditions that keep a family whole across generations.
We built the CenturyHouse Method so that any family can use it. You do not need a million dollars, a family office, or an attorney on retainer. We took something that once belonged to dynasties and made it simple enough for a Sunday afternoon at the kitchen table.
The only requirement is that you care enough to try.
5-7 minutes. No cost. An honest picture of where your family stands today.
