Why 1618

The number
behind everything.

1618 isn't just our name. It's a principle — one that has governed natural growth, architectural proportion, and timeless beauty for thousands of years. We built our firm around it because we believe the best financial plans follow the same laws.

Why 1618?

1618 isn't just a number. It's a ratio — 1.618 to 1 — known for thousands of years as the Golden Ratio, or phi (φ).

You'll find it everywhere nature grows with intention. In the spiral of a nautilus shell. The branching of a tree. The arrangement of seeds in a sunflower. Ancient architects embedded it in the Parthenon. Renaissance painters used it to compose their masterworks. It is, quite simply, the mathematical fingerprint of things built to last.

We named our firm 1618 because we believe great financial planning follows the same principles. It isn't about chasing the market or following the crowd. It's about finding the right proportions — balancing growth and preservation, risk and stability, today's needs and tomorrow's goals — in a way that's uniquely calibrated to your life.

When your financial plan is built in the right proportions, something remarkable happens. It doesn't just work. It compounds. It endures. It grows the way nature intended.

"That's what we build at 1618. Not just a plan — a golden one."

Mark Chalem, CFP® — Founder of 1618 Wealth
About

Built from
Southern Illinois.

I'm Mark Chalem, CFP® — born and raised right here in Carbondale, Illinois. My father ran a small business in this community for 35 years. My mother was a physician assistant who retired as a professor from SIU. This town is not just where I work. It's who I am.

After nearly a decade as a financial advisor at a large national firm, I saw firsthand how the big firm model operates — and who it truly serves. High fees, limited investment options, corporate quotas, and conflicts of interest baked into every recommendation. I left to build something better.

1618 Wealth exists for one reason: to give the people of Southern Illinois access to independent, fiduciary financial planning calibrated — like the golden ratio itself — to perfectly balance your needs, your goals, and your future.
