ASPEN’s Fellows are outstanding leaders in nutrition support, consistently contributing in education, practice, research and service to the field. A Fellow of ASPEN (FASPEN) designation is the highest honor available to members. These individuals have records of exemplary achievements.
Annually, ASPEN’s Fellow Selection Committee reviews candidate nominations, seeking the top candidates for the new class of FASPENs. ASPEN’s Board of Directors reviews the committee’s recommendations, and the new class is recognized at the ASPEN Nutrition Science & Practice Conference.

- Maintain ASPEN membership
- Support ASPEN’s mission
- Serve as mentors to other ASPEN member(s)
- Be a thought leader
- Support the ASPEN Rhoads Research Foundation
- Identify and sponsor future FASPEN candidates
