OUR STORY
Our grandfather, Imre J. (Jimmy) Rosenthal, started our business more than 87 years ago with a simple mission to provide lines of credit to entrepreneurs who could not otherwise obtain financing from traditional institutional lenders - the very definition of alternative financing.
Today, we continue his legacy by honoring his vision and supporting businesses at every stage of their growth.
We’re there when things don’t go as planned, for the occasional–and inevitable–business hiccups when they happen, and we’re always quick to respond to a client’s needs as they change. After eight decades, we’re still a private, family run business and we care about our clients’ success.
