About Us

In addition to research, Workwell offers cardiopulmonary exercise testing (CPET) to evaluate disability impairment for Chronic Fatigue Syndrome/Myalgic Encephalomyelitis (CFS/ME), Fibromyalgia Syndrome (FMS), and other fatiguing conditions. Please contact Jared Stevens, Clinical Coordinator, with any inquiries.

Our Team

Staci-Stevens,-MAStaci Stevens, MA
Founder, Exercise Physiologist

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 developed continuing education curricula for CFS in conjunction with the CDC for physical therapists and other allied healthcare professionals. 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 patients with CFS/ME. Her primary research interest is in functionally characterizing CFS/ME and improving quality of life for patients with the illness.

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

Dr. Chris Snell is a native of Nottingham England and earned a doctorate in Exercise and Movement Science from the University of Oregon, Eugene. Currently he teaches courses in motor control and learning, and exercise psychology in the University of the Pacific’s Health, Exercise and Sport Sciences Department. His research interests center on the functional aspects of CFS/ME, particularly as they relate to quality of life issues. Dr. Snell has both published and presented on this and other topics related to CFS/ME. He is presently part of a research team that uses exercise testing to evaluate physiological functioning in persons with fatiguing illnesses, focusing principally on metabolic processes. Dr. Snell is a former chair of the Chronic Fatigue Syndrome Advisory Committee, sponsored by the U.S. Department of Health and Human Services.

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 chronic fatigue syndrome/myalgic encephalomyelitis (CFS/ME). 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 CFS/ME and related neuroimmune disorders. His experience as both a clinician and a research collaborator provides a unique perspective on CFS/ME 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.

J.-Mark-VanNess,-PhJ. 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 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 CFS, especially as they contribute to physical and cognitive dysfunction.

Todd-ETodd 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. 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 teaching as an assistant professor of physical therapy in the Thomas J. Long School of Pharmacy and Health Sciences at the University of the Pacific. His research interests broadly include the identification of best practices in diagnosis, treatment and prevention of disability related to musculoskeletal pathology. His current research explores which interventions are optimal for individuals with long-standing symptoms, such as chronic fatigue and foot pain, as well as the psychological implications of wellness and disability. He serves as Editorial Review Board Member for the Journal of Orthopaedic and Sports Physical Therapy, and reviewer for Manual Therapy, Physical Therapy, and Arthritis and Rheumatism. Dr. Davenport is active in the American Physical Therapy Association, and he is a past recipient of several distinguished teaching and publication awards.
