Leadership Comments

“Growing up around my dads imaging practice, I saw firsthand the profound impact of misdiagnosis. When a diagnosis is missed or delayed, it can quickly change the course of someone's life,” said Rustin Rassoli, founder, and CEO of Epsilon Health. “Americas growing shortage of radiologists is putting real lives at even greater risk the system is collapsing and patients are bearing the brunt of it.

“I’ve sat across from many patients whose path forward hinged on a single image and having a great radiologist to read it. But there simply aren’t enough of them,” said Dr. Alexi Nazem, MD, General Partner at AlleyCorp. Epsilon let's that expertise reach far more people, with each reading improving the system for the next.
