Jonathan Grinnon, CFA

Fractional CFO and finance and operations executive with more than 25 years of experience helping growing companies scale with confidence.

I turn complexity into clarity. That means building financial models that guide multimillion-dollar decisions, streamlining operations for efficiency and profitability, and lining up strategy with execution across the business.

Whether I am leading a funding round, tightening back-office systems or mentoring a leadership team, I bring a hands-on, 360° approach that balances precision with pragmatism. Clients value how quickly I plug in, the questions I ask, and solutions built for sustainable growth.

I am a CFA charterholder with a BBA in Finance from Villanova University, a former collegiate athlete, and a lifelong team builder on the course, on the court and in the office. I do my best work where trust, transparency and performance matter.

The name Livingston Financial comes from Jonathan Livingston Seagull, the story of a gull who refused to settle for the ordinary and kept flying higher. That's the idea behind the seagull in our logo and our promise: Soaring Above Expectations.

If you are a founder, operator or investor looking for a strategic financial partner, I am open to conversations about fractional engagements, advisory roles and collaborative problem-solving.
