Who We Serve

Three Communities.
One Fiduciary Standard.

Most advisors are generalists. We are not. Every strategy we build is designed around the specific laws, benefits, and pension systems that govern your community.

The Fiduciary Difference

Built for communities
like yours

Sirmium Capital was founded on a straightforward premise: the communities that served New York deserve advisors who actually understand their financial world — not generalists guessing at it.

Our CIO, William Harrison, publishes quarterly equity research covering long-term value investing, capital allocation, and sector analysis. Every client receives this research free.

As a fee-only RIA, we are legally bound to act in your best interest. No product sales. No embedded commissions. No conflicts of interest — ever.

"Long-term wealth isn't built on generic advice — it's built on understanding the exact rules that govern your money and applying patient, disciplined capital allocation over time."

— William Harrison, CIO & Portfolio Manager, Sirmium Capital
