Jeff Greenberg


Primary Care Provider (PCP)

"I try to empower patients to achieve their goals by supporting them over time and being there whenever they need me."

University of Pennsylvania


“Jeff is a very thorough and thoughtful doctor. He listens to your concerns and provides input. I liked the interaction via the app and the video meeting too.”

Dennis S, Firefly Patient


After working in the traditional model for quite some time, Jeff Greenberg knew there had to be a better way to deliver quality primary care to his patients. When he realized there wasn’t, he decided to create one. Jeff started Firefly Health in an effort to improve our healthcare system by providing patients with access to primary care when they need it most. Since then, Jeff has dedicated his career to supporting and empowering his patients in order to help them lead healthier lives.
