Minnesota Board of Directors

Jamie Engebretson, President

I am a physical therapist with a neurologic certified specialty and practice at Bethesda Hospital’s Outpatient Clinic. I enjoy working to optimize people’s lives through therapy and educate individuals with Parkinson’s Disease on resources and research available. Over the years, I have educated various support groups and therapists on Parkinson’s Disease and the various treatment options.


Dr. Gregory F. Molnar, PhD, Vice President

I joined the Board of Directors in early 2018 and have been a very active member since then. I am committed to the efforts of APDA Minnesota, and hope that APDA Minnesota will continue to grow in support of those who are impacted with PD in our community.
I have over 20 years of experience in the study of PD and as a medical device innovator. I was previously the Director of Neuromodulation Research at Medtronic Inc. I currently serve as an associate professor of neurology at the University of Minnesota and Udall Center, and was more recently announced to be the Chief Scientific Officer for a new start-up business in the Twin Cities, SynerFuse.
My wife Gabi and I, and our two children, enjoy the outdoors and spending time at our lake cabin.


Erin Holker, Ph.D, LP, ABPP-CN, Secretary

I am a board-certified neuropsychologist and Assistant Professor at the Neuropsychology Laboratory of the University of Minnesota. I completed my Ph.D. in Clinical Psychology at the Pacific Graduate School of Psychology (Palo Alto University), in Palo Alto, California, a predoctoral internship at the Memphis VA Medical Center, and my postdoctoral fellowship in Clinical Neuropsychology at Mayo Clinic in Jacksonville, Florida, before coming to the Neuropsychology Laboratory at the University of Minnesota in 2001.
I have had an interest in movement disorders since my postdoctoral fellowship. I am a co-investigator for the Clinical Core at the University of Minnesota Udall Center of Excellence for Parkinson’s Disease Research. I provide neuropsychological evaluations for all patients at the University of Minnesota who are interested in deep brain stimulation surgery. I also have a general practice including evaluation of individuals with a wide variety of neurocognitive disorders, including those associated with cerebrovascular disorders including stroke, cancer and its treatment, degenerative brain disease, traumatic brain injury, infectious diseases, and psychiatric conditions.


Stacie Usem, Treasurer

I am a Partner at Lurie, LLP, a public accounting and consulting firm based in Minneapolis. I focus my practice on professional services companies with a specialization in the healthcare industry. I am also very involved in non-profit organizations and have a passion for giving back to the community. When not at work or volunteering, my husband Jeff and I, and both our sons are die-hard University of Wisconsin-Madison Badger fans as we are all alumni.


Beth Zander

I am  a Research Coordinator and the Medical Education Research Advisor in the Department of Neurology at the University of Minnesota.  The majority of my work is with Parkinson’s Disease and PSP studies. I  am deeply appreciative and impacted by the generosity of the patients and families who volunteer for research in Movement Disorders at the University.  It is through their generosity that strides are being made in Parkinson’s Disease and other movement disorders


Susan Vold, BSN, RN, BA, PHN, HNB-BC

I am a board certified holistic nurse who manages patient care within the movement disorders clinic at the University of Minnesota MHealth Fairview. I have extensive experience working with patients with Parkinson’s disease, essential tremor, and dystonia. In addition, I manage the DBS Program: lead consensus meetings for the approval of DBS surgeries, manage patient care before DBS workup, and assist with DBS device management after surgery. I lead patient education classes in Parkinson’s disease and deep brain stimulation. I am a speaker for the Parkinson’s Foundation, Minnesota Chapter and the American Parkinson’s Disease Association (APDA). I am currently a board member of the APDA.


Dr. Eleanor Orehek, Medical Director

I have been caring for patients with Parkinson’s Disease since 2009 when I started neurology residency at Boston University. I am happy to have been able to return here to my home state of Minnesota to continue in this care. It was during residency in Boston that I found an interest and passion for, not only the medical aspects of the disease, but the human side of treating people with Parkinson’s Disease. Working with patients and their families, learning patients’ stories and coming up with a care plan that addresses their individual needs is what motivates and inspires me. What you start to realize as a physician is that there’s a limit to what you can do during the clinic visits. How that care plan is implemented largely depends on the patient themselves, and other people in their care network, the caregivers, therapists, support groups, as well as access to good information and ways to exercise. I am thrilled to be involved with an organization like the APDA that aims to help fill in these gaps for patients and their families and works with communities on awareness and education.


Dr. Michael Park

Dr. Park received his M.D. and Ph.D. from the Department of Molecular and Integrative Physiology at the University of Kansas (KU) in Kansas City, KS, and received a Bachelors in Biology from KU in Lawrence, KS, and dual Bachelors in Electrical Engineering and Economics from Cornell University in Ithaca, NY. He was a 2009 recipient of the William P. Van Wagenen Fellowship and studied at the Assistance Publique L’Hopital d’Adulte de la Timone, Marseille, France.


Devyn Bauer

Currently, I am pursuing a M.S. in Biomedical Engineering at the University of Minnesota while working full time. At my job, I research the pathophysiology of Parkinson’s Disease (PD) and mechanisms of Deep Brain Stimulation (DBS) in the Neuromodulation Research Center.  I aim to fully understand movement disorders like PD, associated changes in motor and non-motor functions, and the impact that movement disorders have on quality of life. My long term goal is to practice medicine at an academic university and assist research. From my time spent researching PD and interacting with individuals with PD, I’ve learned that community members with PD need more support in their day to day lives. For this reason, I joined APDA to help those community members NOW. My passion for improving the lives of community members with PD has only increased after attending APDA events. It is a pleasure to be a part of APDA, an organization that can improve the quality of life for people with PD through education, awareness, and more.


Dave Ihle, Past President

My journey with Parkinson Disease began in the summer of 2015 when I was diagnosed with PD. It was a struggle to understand the disease so I looked for as much information as I could. This led me to the Minnesota Chapter of the APDA. I was encouraged to join the Board of Directors, and I became a member of the Board in late 2016.

I retired from 3M in June of 2015 after a 33 year career in the Manufacturing and Supply Chain organizations. I am looking forward to helping serve those with PD in the Twin Cities’ community as well as learning more about the disease and possible treatments.
