Founder/Principal

That means clean books, organized processes, tax-aware planning and preparation, and transparent reporting—plus the strategic and emotional support to help you feel in control of your financial life.

Lucas’s background spans arts, architecture, and social services—an eclectic mix that grounds their approach in both financial discernment and real-world empathy.
We also provide fractional CFO services with the diligence of a full finance department, without the red tape. Whether you need day-to-day account management, proactive tax guidance, or just someone to help you untangle the financial noise, we're here as a steady, judgment-free partner.

Controller-level work means we don’t just enter transactions—we build and maintain a reliable financial foundation. That includes reconciliations, documentation systems, financial reporting, internal controls, and making sure your books reflect business reality. This level of precision supports tax filings, audits, lender requests, and better planning.

For most businesses, monthly support—including reconciliations, payroll coordination (with 1099s), and year-end tax filing—starts around $550/month. That includes clean books, reliable reporting, and proactive communication to help you stay ahead.
If your operations are simpler or seasonal, we’re happy to tailor a more streamlined package. The goal is to match the scope of work to your actual needs—no more, no less.

We’re small on purpose—so you get direct access, consistency, and thoughtful follow-through. Our work blends rigor with what we call “fiscal therapy”—we don’t just report the numbers, we help you to understand them.
Unlike many firms, we don’t push templated solutions. We learn your business, anticipate your blind spots, and partner with you to build processes that support your goals—not just compliance.

Yes. Entity selection has real tax and cash flow implications, and we help clients assess when an S-Corp election, an LLC, or even just a DBA makes financial sense. We can also handle the filings and implement payroll systems that align with the new setup.

The name is a nod to my family's long line of accountants—my great-grandfather, grandfather, uncle, and father were all in the profession. While this practice is my own, I carry forward their values: integrity, precision, and long-term thinking.
“& Father” also reflects a broader principle: financial systems should be built to last—and built to be handed off. Whether you're passing down a business, preparing for a new life stage, or just trying to stay organized, I believe in creating structures that others can step into with confidence.
