Mark Henderson, CPA

FOUNDER | ROSEHARBOR ADVISORY

I'm a Florida-licensed CPA with more than seven years in financial reporting, technical accounting and transaction advisory. I've worked with private equity investment teams, portfolio companies and corporates in business services, healthcare, construction, manufacturing and distribution, usually hands-on in the general ledger alongside the finance team. I also use automation tools like Alteryx and Claude to speed up reconciliations, data prep and reporting.

Roseharbor offers that same Big 4 and deal-team approach to owners and investors who need clean books, reliable forecasts and thorough diligence.
