Financial leadership, CFO advisory, internal controls

F&M CPA becomes a trusted extension of your business, delivering accounting, tax strategy, business consulting, forecasting, and Part-Time CFO leadership through one experienced team headquartered in Westerville, Ohio.
F&M CPA, LLC was founded by a husband-and-wife CPA team whose initials give the firm its name. It began with a simple conviction: business owners deserve deeply personal service and executive-level expertise — not one or the other.
Today, F&M is one of Central Ohio's most trusted outsourced accounting and CFO advisory firms — a place where clients gain honest guidance, practical business advice, and long-term relationships they can build a company around.


Mat Marlon Piamonte leads F&M CPA with more than 25 years of combined accounting and financial leadership experience across the firm. Holding CPA, CMA, CFSA, and CICA designations, he brings a rare blend of technical expertise, strategic thinking, and internal-controls discipline to every engagement.
Mat's passion is helping business owners reduce workload and make smarter financial decisions — replacing late-night bookkeeping and reactive tax filings with a real financial team, clear reporting, and a strategic partner who's genuinely invested in the outcome.
"Our clients don't hire an accountant. They gain a finance department, an advisor, and a partner committed to the long game."
