Our Mission

Derryrush Wealth Management LLC is an independent, fiduciary wealth management firm based in West Sayville, New York, serving individuals and families across Long Island.

We are by design a boutique practice, not a large institution. We do not manage thousands of accounts through teams of rotating advisors. We've deliberately capped our practice at no more than 100 families: a limit set by design, not by size.

As a registered investment adviser, we are held to the fiduciary standard. That means we are legally and ethically required to put your interests ahead of our own. It is not a marketing claim. It is a legal obligation, and it shapes everything about how we work.

We work with clients at very different points in their financial lives. Some are running a business that represents most of what they've built. Some are transitioning from earning wealth to living on it. Some are rebuilding after a divorce. The thread that connects all of them is this: they are facing a decision too consequential to get wrong, and they'd rather have real guidance than guesswork.
