Built on Conviction. Driven by Your Success.
For nearly two decades, we've held to a simple belief: that financial advice should be free from conflicts, grounded in evidence, and deeply personal. Everything we do flows from that principle.
"The best financial advice isn't about markets — it's about understanding people."

Born From a Belief That Advice Should Be Pure
In 2025, Jonathan Mercer left a senior position at one of the industry's most prestigious firms. Not because it wasn't successful — but because the model was broken. Recommendations were shaped by product commissions and sales quotas, not by what clients actually needed.
He founded Prime Sentry Wealth Management with a different blueprint: a fee-only, fiduciary advisory firm that would never earn a cent from product sales. An independent firm where every strategy, every recommendation, and every conversation would be guided by one question — what is genuinely best for this client?
That conviction attracted like-minded professionals — portfolio managers, tax strategists, estate attorneys, and financial planners who shared the vision of advice without agenda. Together, they built a firm that serves not as salespeople, but as financial stewards.
Nearly two decades later, Prime Sentry manages over $4.2 billion for more than 1,500 families, entrepreneurs, and institutions. We've navigated clients through financial crises, market booms, tax reform, and life's most pivotal transitions. Through it all, our founding principle has never wavered.
The Principles That Guide Everything We Do
These aren't aspirational statements — they're operational commitments. Every decision we make, from how we structure fees to how we build portfolios, is tested against these principles.
Fiduciary Integrity
Every recommendation we make is legally and ethically bound to serve your best interest — not ours. We operate as fiduciaries at all times, without exception.
Radical Transparency
No hidden fees, no opaque strategies, no fine print. We believe you deserve complete clarity about how your money is managed and what you pay for our guidance.
Client-Centered Design
Your plan is built around your life — not a template. We take the time to understand your unique circumstances, goals, and concerns before crafting any strategy.
Continuous Evolution
Financial markets change. Tax laws change. Your life changes. We proactively adapt your strategy to stay aligned with where you are and where you want to go.
Intellectual Rigor
Our investment philosophy is grounded in evidence-based research, not market speculation. We apply academic discipline and institutional-grade analysis to every portfolio.
Generational Thinking
We don't measure success in quarterly returns. We measure it in decades — helping families build, protect, and transfer wealth across generations.
Milestones That Define Us
From a one-person practice to a nationally recognized wealth management firm — each milestone reflects our commitment to growing the right way.
