Cobalamin Steering Committee


The Cobalamin Steering Committee will come together to provide advice on how to best support the needs of the Cobalamin Community.


  • Provide ideas to HCUNA on what would be helpful to the Cbl community, e.g through periodic calls with executive director and other board members as needed
  • Act as an ambassador to new Cobalamin families - providing them with information, tools, advice and encouragement
  • Help draft, review and provide feedback on content  and materials for new resources being developed
  • Help serve as or organize volunteers as needed for events
