About DailyDoctor

Our mission is to make proactive healthcare accessible for all Americans no matter their age, race, gender, sexual orientation, economic status, or location.

Healthcare-As-Usual Must Change

DailyDoctor Offers a New Model of Care

For a long time, healthcare in America has been reactive - waiting for patients to develop serious issues before providing care. This leads to greater risk of hospitalization and death, especially when treating chronic conditions, which disproportionately affect people age 65 and older, minorities, and those who lack access to quality medical care.

Add to this the growing shortage of medical doctors and you have potential for disaster that our healthcare system can't support.

DailyDoctor (originally called AIRx Health) was founded in 2019 by Stanford-trained MD, Vijay Rajasekhar, who saw an opportunity to address these inequalities and greatly improve patient care by checking in with patients for just 1 minute a day.

Not only could this type of care help identify health issues early so they can be managed before a patient needs hospitalization, it also makes it possible for medical teams to help millions of patients each day at a much lower cost.

Everyone deserves access to the best-possible care. DailyDoctor is the first program to help seniors proactively stay in control of their chronic conditions. And this is just the beginning.
