Why pay $20K in fees just to buy a Big 4 partner a bigger boat?

At Black Marble, your money goes where it should — back into your business, not someone’s fancy new boat on Lake Oswego.

We don’t “check boxes.” We build businesses together.

About Us

I started BLACK MARBLE | Advisory Group on a simple belief: everyone deserves access to the same level of financial wellness—whether you're a mid-market company navigating a $50M acquisition or a graduate trying to navigate their taxes or student loan repayments.

Over the past decade in Big 4 assurance, corporate finance, financial reporting, and SEC reporting, I've worked across the tech, utilities, and manufacturing industries. I've completed technical accounting and due diligence on over $500M in acquisitions, implemented complex compliance standards, and prepared companies for IPO readiness. I've also worked with hundreds of individuals to optimize debt repayment, prepared tax returns for low-income individuals, and taught families to build wealth on any income.

My specialty is translation—turning accounting and finance into insight. From ASC 805 business combinations to personal budgeting, I help translate financial information into usable data to help you work toward your financial goals. Financial literacy shouldn't be a luxury. It's a foundation for a successful financial future.
