Meet the Fellows
WELCOME CLASS OF 2026
Bradley Parke, MD Originally from Georgia, I am excited to return to OHSU/Portland where I got my internal medicine training. Since completing residency, I worked on the Pine Ridge Reservation with the Indian Health Service over the last three years, first as a fellow of rural health with the University of Washington and then as a federal employee. It was there I began to work with improving inpatient care for those with alcohol use disorder and working with a physician task force to offer Suboxone in clinic. The limitations of rural and indigenous care inspired me to pursue ongoing training in addiction medicine. Beyond the pharmacology, I hope to learn what makes highly efficient multidisciplinary teams and systems that best partner with people affected by substance use. Ultimately, I would like to return to rural care to assist in offering comprehensive care to often overlooked populations.
In my free time, I love to travel, especially to natural locations to hike or backpack. I cannot wait to resume exploring all the natural wonders Oregon has to offer! When indoors, I love to bake, cook, and sew - tell me your favorite sweet treat and I'd love to make it for you!
So excited to return to training and learn from you all about how to best help our patients achieve their health goals!
Emma Fenske, DO I am originally from New Mexico but relocated to Oregon to complete my internal medicine residency at OHSU. Pursuing an addiction medicine fellowship felt like a natural next step, as it closely aligns with some of the passions that have shaped my path in medicine—advocacy, harm reduction, and a focus on the humanistic side of care. Many of the most meaningful encounters I’ve had so far have been with patients navigating substance use disorders. Another part of the field’s appeal is being able to proudly share that the NNT for buprenorphine is better than many medications we prescribe without a second thought—offering a great opportunity to spark curiosity and advocacy among colleagues. I’m humbled and grateful to stay at OHSU, drawn by the community and the opportunity to learn alongside so many talented addiction specialists. I'm especially excited to deepen my understanding of substance use in carceral settings and explore the intersection of addiction medicine and global health. Outside of medicine, I love long-distance running, trying new restaurants around Portland, doing anything with my dogs (Bailey & Bruno), riding my motorcycle, traveling, and being out on the water whenever possible. I also have a passion for narrative medicine and have been grateful for the ways my writing has evolved throughout my education and training.
Erin Nacev, MD I grew up on the Olympic Peninsula in Silverdale, WA. I went to the east cost for college at Swarthmore College in Pennsylvania, and spent my Junior year in Buenos Aires, Argentina. After college, I moved to San Francisco to serve two AmeriCorps terms at a Department of Public Health family health center, where I worked as a health coach for patients with chronic conditions and helped start a patient advisory council. I went to medical school at the University of Wisconsin-Madison, where I was a member of the Training in Urban Medicine and Public Health and spent my clinical years in Milwaukee.
I came to Portland for OBGYN residency, and feel lucky to be staying at OHSU for Addiction Medicine fellowship. I plan to work as a general OBGYN with a focus on caring for those who use substances, providing the full scope of reproductive health care, supporting patients during and after pregnancy and through gyn and surgical care. I am interested in improving care for patients with substance use disorders during pregnancy as well as those seeking abortion care. My research interests have centered around reproductive health policy, the intersection of mental health and substance use in pregnancy, as well as qualitative health services research.
Outside of medicine, I enjoy spending time with my husband and two kids (ages 1 and 4), walking my lab mix Rosie, cooking and baking, and doing crossword puzzles.
Michelle Pies, DO OHSU Addiction Medicine Fellowship is the clear choice for me. I am an Oregon native committed to caring for and improving health access for all humans. I completed my Family Medicine Residency in Corvallis and spent the last decade working as a hospitalist in Oregon. While I enjoy the acuity of inpatient medicine, over the last few years, it has become increasingly apparent our community would benefit from more education and availability/ accessibility of evidenced-based treatment for those impacted by substance use and addiction. Throughout my life, I have developed immense compassion and empathy for those who are impacted by substances. I’ve witnessed people I love, humans I’ve cared for and the families/ friends that love them, struggle with the challenges of finding care and accessing treatment resources. I’ve also seen the devastating effects of the derogatory stigma periodically associated with addiction and substance use. Because of these experiences, I want to be part of the positive, forward movement to provide unconditional compassion, eradicate care barriers, educate anyone ready to learn and at the same time, keep focus on the human in the center of our care. With this fellowship training, it is my goal to work in support of all humans whose lives have been touched by substances and addiction. I am honored to be part of the Addiction Medicine Team at OHSU. I look forward to each opportunity to learn, educate, support, treat, and contribute to the growth of addiction medicine. When I am not working, I enjoy landscape photography, traveling (to take more photos), adventuring outside, gardening, and cooking. I have a small farm full of furry and feathered friends who regularly remind me it is the simple things that matter most. Then to stay centered with gratitude, I have a loving spouse, family and friends who support me in this journey.
