Laurie K Mischley, ND, PhD, MPH

Dr. Laurie Mischley ND, MPH, PhD studied naturopathic medicine (ND) at Bastyr University. From there, she went on study epidemiology (MPH) and nutritional sciences (PhD) at the University of Washington. Her work is focused on identifying the nutritional requirements unique to individuals with neurodegenerative diseases. She has published studies related to coenzyme Q10, lithium, and glutathione deficiency in Parkinson’s Disease (PD).

As a clinical researcher, she has worked with the FDA, NIH, and the Michael J. Fox Foundation to administer intranasal glutathione, (in)GSH, to individuals with PD. Drawing on expertise in radiology, epidemiology, nutrition, neurology, and naturopathic medicine, she is attempting to determine whether (in)GSH boosts brain glutathione and improves health.

Dr. Mischley has served on the Bastyr University Institutional Review Board since 2010 and regularly provides mentorship to students interested in integrative medicine research. She founded the social purpose corporation, NeurRx; developed an outcome measure to assess PD severity; and is author of the books Natural Therapies for Parkinson’s Disease and Cannabis Use Survey: Insights, Confessions, & Opinions.

She has given presentations on Parkinson's Disease research at conferences in the U.S. and abroad.  The following are some of the recent poster presentations:

Dr. Mischley maintains a small clinical practice at Seattle Integrative Medicine where she works exclusively with patients with Parkinson's.

John Duda, MD

John Duda, MD, is the director of the Parkinson's Disease Research, Education and Clinical Center (PADRECC)  and the Co-Director of the Center for Neurotrama, Neurodegeneration and Restoration of the Philadelphia VA Medical Center, the National Director of the PADRECCs for the Department of Veterans Affairs, and an Associate Professor of Neurology at the Perelman School of Medicine at the University of Pennsylvania.

As Director of the Philadelphia PaDRECC, he participates in the care of almost 1,000 Veterans with Parkinson's Disease and has had a long interest in integrating lifestyle modifications in the care of these Veterans, as well as speaking at numerous support groups and national scientific meetings on the role of nutrition in the management of PD. He also started the Brain Wellness Clinic at the Philadelphia VA, focusing on lifestyle modifications for maintaining brain health. His research activities include basic science investigations into the cause of Parkinson's disease and how traumatic brain injury relates to PD. He also has ongoing research projects studying the effects of a plant-based, whole food diet on PD as well as how the gut microbiome changes in PD.

He has received research grants from the Department of Veterans Affairs, the National Institutes of Health, the Michael J. Fox Foundation for Parkinson's Research, the Samueli Foundation and the Pennsylvania State Department of Health. He is currently on the editorial board of npj Parkinson's Disease and has served as a peer reviewer for over 30 journals. He has authored more than 100 scientific publications including articles in JAMA, Science, Neuron, The New England Journal of Medicine and Neurology

Karen Raphael, PhD

Dr. Karen Raphael, PhD is a psychologist and epidemiologist whose work over nearly the past 25 years has focused on medically unexplained musculoskeletal pain. After completing postdoctoral training in psychiatric epidemiology, she has held faculty appointments at Columbia University (at one point holding simultaneous appointments in Epidemiology, Psychiatry, and Dental Community Health) and Rutgers University, where she served as Director of Research in the Dept. of Psychiatry. Since 2009, Dr. Raphael has been a tenured professor at the New York University (NYU) College of Dentistry and in the Dept. of Psychiatry at NYU Langone School of Medicine.

In addition to serving as Principal Investigator on multiple NIH grants totaling well over $10M, she has published more than 70 manuscripts and served on numerous editorial boards and grant review committees, and presenting her research findings internationally.

Karen first experienced symptoms of Parkinson’s disease while trekking toward Everest Base Camp in Nepal. Seven years later, through a combination of prescription medication, supplements, meditation, a life-long vegetarian diet and an intensive, evidence-based exercise program, she hopes that – like her father who recently passed away from PD complications — she can model the characteristics of a ‘positive outlier,’ sharing the lifestyle factors that have supported her quest to seek a healthy and joyful life, living with PD.

samantha evans, nd


Samantha Evans, ND graduated from Bastyr University and is the current Resident Physician to Drs. Laurie Mischley and Marco Vespignani. While attending Bastyr, her studies focused on neurology and Parkinson's disease and she worked as a Research Assistant on the epidemiological study. Dr. Evans frequently speaks at PD support groups throughout the Pacific Northwest.

In her practice at Seattle Integrative Medicine in Seattle, WA, her focus is how gastrointestinal health impact PD and works with patients to identify causes and navigate treatments for Small Intenstial Basterial Overgrowth (SIBO), H. Pylori, low stomach acid, dysbiosis and more.

Dr. Marz has participated in almost 400 triathlons over the past three decades. He is currently involved in the study of "Blue Zones", areas around the world in which people live longer and healthier. His ambition is to identify the "Ideal Human Diet" for health and longevity. A vegan himself, Dr. Marz will cause you to question assumptions about aging and will make a compelling case that personal health and planetary health are inseparable.

jason allen, ND, MPH


Dr. Jason Allen specializes in environmental medicine in Seattle, WA. He earned his ND from Bastyr University in 2003 and his Master's in Environmental Medicine and Toxicology at the University of Washington. Well water, pesticides, dairy, and numerous other environmental insults have been linked to a greater risk of PD.

During this conference we'll address whether toxicants contributed to the development of your PD and what you can do about it. Dr. Allen will review the data on environmental risks to neurological health, make suggestions for reducing exposure, and address the topic of "detox."

rachel bennett, nd(c), mph

Rachel Bennett, ND(c), MPH earned a Master in Public Health in Epidemiology from Indiana University School of Medicine and currently studies naturopathic medicine (ND) at Bastyr University. She currently conducts research with Dr. Mischley, with a passion for nutrition, epigenetics, neuroendocrinology and food as medicine. Rachel's extensive regulatory training enables her to effectively assist Dr. Mischley in the execution of clinical trials and epidemiological surveys related to PD. She presented the association between social health and PD progression at the World Parkinson's Congress in 2017 in Portland, OR and lectures throughout the Pacific NW on topics such a gastrointestinal health in PD, cannabis use, and immune activation. She has been following a ketogenetic diet for a year and half and will discuss how such a diet may be capable of improving metabolism and neurological health.
