Why We Do What We Do
I'm Sergio Mariaca and I opened Mariaca Wealth to provide clients with an honest, fully transparent option to high-fee, high-commission brokers.
I grew up in Puerto Rico with parents who were both successful entrepreneurs. They taught me how hard work and perseverance can help a family achieve great financial success. Unfortunately, their experiences also taught me how quickly life’s curveballs can decimate everything a family has built.
Shortly after my parents retired, my father was diagnosed with pancreatic cancer. They had limited insurance coverage, which led to over $1,000,000 in medical bills. My father passed away, and my mother was left alone with a terribly depleted nest egg. To make matters worse, her broker had invested a large amount of her remaining nest egg in dot.com stocks that were about to come crashing down.
It's impossible to see people you love go through that kind of experience and not be affected by it. I immediately shifted my focus from the law to finance and became a wealth advisor. After working in the field for a few years, I saw how brokers constantly padded their pockets with hidden commissions and unnecessary fees that their clients were paying without even realizing it. And, while it was legal, it just wasn't right.
That's why I joined the 3% of wealth managers held to a higher legal standard, that of a fee-only fiduciary. As a fee-only fiduciary, I always make recommendations that are in my clients "best interests." I also use my expertise and fiduciary status to strip away unnecessary fees and commissions and I help my clients invest in low-fee, long-term products with zero commissions and 100% transparency.
Bottom line? I love helping families enjoy rich full lives and the financial freedom they've worked so hard to earn.

Our Values
Uncompromising Alignment
As a fee-only, CEFEX-certified fiduciary, our structure is designed to completely eliminate conflicts of interest. We operate with absolute transparency and intellectual honesty, ensuring our structural advice and portfolio architecture are driven solely by what is optimal for your family and your enterprise.
Strategic Clarity
Wealth creates complexity, and complexity can breed strategic paralysis. We act as your financial architects, synthesizing the intricate, moving parts of your corporate and personal balance sheets into a clear, actionable blueprint. We distill the complex so you can make decisive, highly informed decisions with absolute confidence.
Proactive Stewardship
Managing significant wealth is an ongoing discipline, not a static event. We maintain a continuous, high-touch dialogue to anticipate structural challenges, proactively adapt to evolving tax legislation, and purposefully educate the rising generation for the responsibilities of the wealth they will inherit.
The Multi-Disciplinary Advantage
Significant wealth requires more than a single perspective. It requires coordinated thinking across investments, tax planning, estate planning, risk management, business strategy, and family priorities.
At Mariaca Wealth Management, we serve as your personal CFO and central advisory hub. We conduct a comprehensive review of your financial life to identify structural vulnerabilities, uncover planning opportunities, and help architect sophisticated solutions.
Rather than relying on a static roster of in-house professionals, we operate with an open-architecture model. This allows us to source and coordinate a curated network of highly specialized independent experts tailored to your exact complexity, while continuing to collaborate closely with your existing tax, legal, and professional advisors.
The result is a more integrated advisory experience: your core planning disciplines aligned, your advisors working in unison, and your wealth strategy built with the depth and precision significant wealth deserves.
Strategic Alignment: We align your overarching wealth strategy and complex financial transitions directly with your family's core values and legacy objectives.
Elegant Architecture: We leverage decades of expertise to distill intricate financial, tax, and legal complexities into clear, sophisticated, and actionable solutions.
