From our team
“The experience of getting primary care is reorienting around the needs of individuals. Imagine getting primary care from a platform built with your needs in mind, that achieves better health outcomes, and reduces the long-term cost of your care. That’s the advanced virtual care model.”
Andy Ellner, MD, MSc
Chief Clinical Advisor, Firefly Health
