About
With over 15 years of bookkeeping and accounting experience, I’ve built my career around helping small businesses bring order, clarity, and structure to their finances. My foundation began with day-to-day accounting—managing accounts payable/receivable, reconciling bank statements, handling payroll, and ensuring accurate financial records. Over the years, I’ve worked with a variety of industries, but I’ve specialized in supporting construction contractors, service-based businesses and nonprofits who often struggle with tight margins, inconsistent cash flow, and the challenges of scaling operations. This hands-on experience taught me not just how to balance the books, but also how to spot inefficiencies, reduce costs, and highlight opportunities that owners may overlook. My approach has always gone beyond simple compliance—I make sure my clients not only stay organized and tax-ready but also understand their numbers so they can make smarter business decisions.
Today’s Evolution: Strategic Partner & Fractional Controller While bookkeeping and accounting remain the foundation of my work; my role has naturally expanded into more strategic financial leadership. Many of my clients reach a point where they don’t just need reports—they need insight and direction. That’s where my Fractional Controller services come in.
As a Fractional Controller, I provide high-level financial oversight without the cost of hiring a full-time CFO.
