Audio interview with Doximity co-founder Nate Gross, Doximity is essentially Linked In for physicians. Its a real-name on-line network that docs can use to connect with their existing network and beyond. The company has pre-populated profiles based on licensure information, and allows docs to claim their profiles and hit the ground running. Its a secure HIPAA-compliant platform which allows for sharing of attachments (which could be lab results, images, etc.)
