The Fiduciary Difference
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.
Off the clock, the same belief: Sirmium Capital is the founding sponsor of the NYC Honor Foundation, a 501(c)(3) pairing elite youth basketball with financial literacy and NIL education, and our professionals teach its financial curriculum pro bono.
"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, Founder & Chief Investment Officer, Sirmium CapitalAs a fee-only RIA, we are legally bound to act in your best interest: no investment product sales, no commissions.

A niche-specific strategy built around your community's exact rules, not a template.
Quarterly research, regular reviews, and fiduciary oversight as your life evolves.
Sirmium Capital works primarily with 9/11 families, retired FDNY and NYPD officers, veterans, nurses, nurse practitioners, physician assistants, and physicians: people navigating complex pension, 457(b), TSP, VCF, or healthcare-professional income situations that general financial planning often misses.
A flat 1% annual advisory fee on assets under management. No commissions, no product sales, no hidden charges. Fee-only, registered investment adviser.
As a registered investment adviser, Sirmium Capital is legally required to act in clients' best interests at all times. Recommendations must be suitable, fees must be disclosed, and the adviser cannot earn commissions or referral fees from product sales. This is a higher standard than the suitability standard that applies to brokers.
