At SHIFT, we believe in treating the root cause with a patient-centered approach.

We practiced conventional medicine for years. There is nothing more disheartening than seeing a patient continue to struggle, despite doing everything we were taught in traditional medical training. 

Meet Our Practitioners

Dr. Marie Agnew DNP, FNP-C 

Marie spent years searching for answers to her own health struggles, only to be met with the same one-size-fits-all approach- pills to mask symptoms. The answers she was given did not resonate with her, propelling her onto a journey of exploration including years of extensive training in Ayurveda, Mindfulness Meditation, Nutritional Therapy, Yoga Therapy, Allopathic Medicine and Functional Medicine.

In 2007, she began her formal medical training at Oregon Health and Science University in Portland, Oregon and became a critical care RN. In 2010, she returned to OHSU where she obtained a Masters of Science degree and became certified as a Family Nurse Practitioner. A few years later, while practicing as a FNP in a busy rural Oregon practice, she completed her dissertation at OHSU on meditation and mindfulness for the treatment of chronic pain. That same year, she published her work in a medical journal, and obtained a Doctorate in Nursing Practice.

She has since honed her allopathic and integrative medical knowledge by advanced training from the Institute of Functional Medicine (IFM), serving as a key consultant in the development of a functional medical practice and lifestyle program in Portland, OR and many years of practicing in urgent medicine, integrative medicine, and primary care. Marie is a firm believer in the foundations of health- sound sleep, hormone optimization, personalized nutrition, healthy relationships, and realistic strategies to decrease stress and toxic burden on the body.

To have time and the ability to truly address these foundations of health, Marie launched SHIFT Functional Medicine and is now thrilled to have a team of excellent providers that she has since brought into her practice.

When Marie is not in the clinic she enjoys practicing yoga, exploring trails, experimenting with new recipes, and spending time with her husband and two children.

Dr. Ashley Gish DNP, WHNP

Ashley Gish, functional medicine provider and women’s health specialist is on a mission to help women identify wellness strategies that work, stop wondering if it’s all in their head, and start living their best life.

Whether you need an annual exam, want to talk birth control, or want to start trying for pregnancy, Ashley has you covered for all things women’s health and hormones.

She is excited to be joining SHIFT Functional Medicine in creating a holistic, root-cause approach to patient care. She strongly believes in utilizing modern medicine and traditional wisdom including nutrition therapy, exercise, herbs and supplements, as well as mind-body practices to empower patients to make healthcare decisions that make sense for their lives.

Ashley attended the University of Utah where she received her doctorate in women’s health as a nurse practitioner. While there she also earned degrees in behavioral health science and health psychology. Prior to working as a nurse practitioner she spent many years working in public health and as a certified yoga instructor teaching both community classes and working with corporate wellness programs. In 2012, she worked with a small team to develop and implement the pilot program teaching yoga and meditation for pediatric oncology patients at Primary Children’s hospital in Salt Lake City, UT.

Food is her love language and she has spent the majority of her life working on organic farms, cooking for yoga retreats and “testing” new recipes on her friends and family.

After seeing many women continue to struggle with the one-size-fits-all approach that was offered in conventional medicine she began training in functional medicine and has found it to be the perfect mix of science and the art of individualized patient care.

Ashley lives in Bend, OR with her husband and two little girls, Juniper and Indi. When not in clinic, you will likely find her experimenting in the kitchen, digging in her garden, or exploring one of the many beautiful trails central Oregon has to offer.

What They’re Saying

"Every time I seek medical advice from Dr. Marie she listens, I mean really listens. She asks probing questions to find out what is going on and what the root cause is. Dr. Marie is great about follow up and truly cares about me and my family's health."

Amy P.

“As a patient of Dr. Agnew, I am treated with professionalism, kindness, and compassion. Dr. Marie is gifted in her ability to listen carefully and make a thoughtful, informed diagnosis. She has a curious mind and genuinely wants to help you heal. I appreciate her ability to translate and share the right amount of science to aid in my understanding. I’m glad to have found her!”

Lindsay G.

“Dr. Agnew is one of the most intellectually voracious healthcare providers I have met. She has trained in and demonstrated mastery in many different areas of medicine. Additionally, she is an absolute delight to work with. She is sharp as a tack and highly analytical, but still creative, humble and kind. She strikes an extraordinary balance between smarts and heart. I wouldn't hesitate to refer my patients to her”

Dr. Sara Gillham

“Dr. Agnew brings the best of both worlds to her practice. She integrates aspects of conventional Western medicine with a deep understanding of functional approaches that address the root of disease. She is genuinely interested in supporting her patients to achieve their best state of health, which is apparent with her attention and presence in appointments and follow-through. I trust her for comprehensive and thorough care”.
