About Us

In addition to research, Workwell offers cardiopulmonary exercise testing (CPET) to evaluate disability impairment for chronic fatigue syndrome/myalgic encephalomyelitis (ME/CFS), fibromyalgia syndrome (FMS), and other fatiguing conditions.

Our Team

Staci-Stevens,-MAStaci Stevens, MA
Program Director Workwell Foundation

Staci Stevens holds a bachelor’s degree in Sports Medicine from the University of the Pacific and a master’s degree from Pacific in Exercise Physiology. Ms. Stevens has served on the Department of Health and Human Services Chronic Fatigue Syndrome Advisory Committee and as co-vice president of the International Association of ME/CFS. She has directed several research projects and supervised testing for clinical trials. Her clinical experience is in disability evaluation, cardiopulmonary exercise testing and prescribing activity management programs for people with ME/CFS. Her primary research interest is in functionally characterizing ME/CFS and improving quality of life for people with the illness.

Christopher-R.-Snell,-PhChristopher R. Snell, Ph.D.
Scientific Advisory Committee Chair

Dr. Christopher Snell has over 15 years experience studying ME/CFS and in particular the post-exertional fatigue and malaise that typifies this illness. He is part of a group that was among the first to advocate for use of cardiopulmonary exercise testing to measure fatigue in CFS research. Together they have probably conducted more exercise tests with patients than anyone. Their two-day exercise testing protocol has potential to be a biomarker for both pathology and function in ME/CFS. Dr. Snell is a former chair of the Chronic Fatigue Syndrome Advisory Committee (CFSAC) to the U.S. Secretary for Health. He has published extensively on ME/CFS and lectured in the USA and abroad, including invited presentations for the National Institutes of Health and the Food and Drug Administration.

JaredJared Stevens, BS
Clinical Coordinator

Jared Stevens graduated from Sonoma State University with a bachelor’s degree in Business Administration and is currently pursuing a master’s degree in Public Health. While attending school he became involved in clinical trials, traveling the country to perform exercise tests on patients with ME/CFS. Jared is a certified EKG technician and holds the position of clinical coordinator. He is responsible for the overall operations of Workwell Foundation in addition to scheduling patients and performing cardiopulmonary exercise tests.


Daniel L. Peterson, MD
Medical Supervisor

Daniel L. Peterson, M.D., is an internist in Incline Village, Nevada and recognized medical expert on CFS/ME. He is a pioneer in the use of cardiopulmonary exercise testing in this patient group. Dr. Peterson has devoted 25 years of his clinical career to diagnosing and caring for patients with ME/CFS and related neuroimmune disorders. His experience as both a clinician and a research collaborator provides a unique perspective on ME/CFS for developing translational science. Dr. Peterson serves on Simmaron Research’s Scientific Advisory Board and in 2011, was appointed Adjunct Professor on the faculty of Health Sciences and Medicine at Bond University in Queensland, Australia.

mark-vannessJ. Mark VanNess, Ph.D.
Scientific Advisory Committee Member

Dr. Mark VanNess received his doctorate in neuroscience from Florida State University in 1997 and did post-doctoral work in the department of pharmacology at the University of Texas Health Science Center at San Antonio. He teaches classes at the University of the Pacific in the College of the Pacific and College of Engineering in the areas of exercise science, nutrition and biology. He began working on ME/CFS in 1999. His main research interest is on the role of the autonomic nervous system in immune dysfunction. He has a particular interest in the mechanisms that produce post-exertional malaise in women with ME/CFS, especially as they contribute to physical and cognitive dysfunction.

Todd E. Davenport PT, DPT, OCS
Scientific Advisory Committee Member

Dr. Todd Davenport is a graduate of the University of Southern California, where he earned his Doctor of Physical Therapy degree and completed a post-graduate Residency in Orthopaedic Physical Therapy. He also earned his Master’s degree in Public Health from the University of California at Berkeley. The American Board of Physical Therapy Specialties recognizes Dr. Davenport as a board certified specialist in Orthopaedic Physical Therapy. He is a past clinical research fellow at the National Institutes of Health, where he studied issues related to physical testing in individuals with fatiguing illnesses. He is currently a full-time faculty member in the Department of Physical Therapy at the Thomas J. Long School of Pharmacy and Health Sciences at the University of the Pacific, and a clinical consultant at Kaiser Permanente. Dr. Davenport is active in the American Physical Therapy Association, and he is a past recipient of several distinguished teaching and publication awards.
