Our Service

The Mobile Appointment service replaces the outdated and inefficient current methods of accessing a registered dietitian in an medical office or clinical setting. We bring nutrition experts to where our users are making their important food and health decisions (i.e. in your home or at the grocery store). With the Mobile Appointment service, you may…

  • Choose your personal dietitian
  • Choose an appointment time to fit your schedule
  • Choose where you want to speak with your dietitian
  • Make an Appointment
