Staci Stevens

Staci R. Stevens, MA in exercise physiology. Founder and Director of Workwell Foundation, Ripon, California, USA. She serves as Co-Vice President of the Board of Directors and Chair of the Membership Committee of the International Association for Chronic Fatigue Syndrome/Myalgic Encephalomyelitis. She served a term on the Chronic Fatigue Syndrome Advisory Committee from 2003 - 2006. Stevens is one of the authors of the 2011 case definition, International Consensus Criteria.

Stevens had (in her own words) a very well-controlled case of myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) for greater than 20 years, which motivates her high commitment to advancing understanding of the illness and helping other patients.
