Nutrition Service At-A-Glance

  • Lunch & Learn Workshops
    Our Lunch & Learns are not those boring ones where everyone looks at the slides and read handouts. We bring fun to the room! We believe people get it when it’s fun and practical. Bringing along props and packaged food products, our dietitian passes along real food products for attendants to touch and see for themselves.
  • Tele-seminar and Webinar
    Our dietitians can use your existing or 3rd party communication infrastructure to deliver tele-seminar or webinar
  • Onsite 1-on-1 Consultation
    Our dietitians can spend a few days at your office to meet one-on-one with your employees
  • Ongoing Remote 1-on-1 Consultation
    Our dietitians can help your employees with their diet remotely. Your employees can submit their food journal and other notes ahead of time via our online portal. This saves you tremendous time and money as our dietitians can pull up data immediately when they are consulting over the phone.
