Given the shortcomings of American healthcare, a growing number of patients have taken matters into their own hands. They’re avid consumers of online health content, driven to optimize their well-being and longevity, and looking to partner with a like-minded provider.
We created Proactive Care to offer accessible, affordable, and personalized care for patients seeking this type of doctor-patient relationship.
