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

What is it about Shift Functional Medicine that makes us so different? We practiced conventional medicine for years. Nothing is more disheartening than seeing a patient continue to struggle, despite doing everything we were taught in traditional medical training. Learn about Shift Functional Medicine by learning who we are, our training and areas of expertise.

Dr. Marie Agnew DNP, FNP-C, IFMCP

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 through advanced studies (including earning her functional certification) from the Institute of Functional Medicine (IFM). In addition, she served as a key consultant in developing a functional medicine practice and lifestyle program in Portland, OR. Agnew also has experience from 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.

Laura Evans MSN, FNP-C

Laura is a family nurse practitioner passionate about working with patients to find root causes of disease instead of symptom-based treatment.  Laura graduated summa cum laude from the University of Wyoming and has practiced as an FNP for ten years.

About four years ago, she realized that we are only treating symptoms of deeper problems at a broad worldly level— and that the medicine that she was practicing fell under the same umbrella.  It was at this time that Laura found the Institute for Functional Medicine and began taking courses.  Her love for medicine was revitalized in these courses and began to shift how she interacted with her patients, herself, and society.  She currently balances working in clinics focused on allopathic care and functional medicine.

Laura grew up in Alaska and is an avid hiker and backpacker with her dog, Ollie.  She has traveled extensively and has walked the Camino de Santiago across Spain twice.  Evans is also a certified yoga teacher and reiki practitioner.  Laura believes the healthier our communities and we are, the more our lives are vibrant and fulfilling.


Jennifer Nelson MSN FNP-C

Jennifer’s interest in functional medicine came long before becoming a medical provider. She spent years battling chronic pain and going from doctor to doctor trying to uncover her auto-immune disorder. Unfortunately, her options included unnecessary surgical intervention and medications riddled with adverse side effects–or she was misdiagnosed entirely.

Through years of steadfast resolve to find alternative care, she found functional medicine, and her quality of life flourished. This was when Jennifer knew she wanted to help patients in this same way—improving the quality of life of her patients’ lives through finding the root cause of their illnesses, not just treating the symptoms.

Jennifer’s nursing education began in 2005 at Seattle University in Seattle, Washington. She started as a school nurse for five years in the Redmond School District before going back to school in 2014 for her master’s degree.

She attended Frontier Nursing University to become a Family Nurse Practitioner to move into functional medicine after training in allopathic care. She spent four wonderful years working at Weeks Family Medicine, caring for acute and chronic illnesses families. While she loved her time in this clinic, she knew her passion was functional medicine.

She is excited to bring her expertise and experience with functional medicine to the SHIFT Functional Medicine team.  She hopes to help others find treatment and relief through a personalized and collaborative approach to functional medicine. Her specific areas of interest include postpartum health, assisting families to be healthier together, managing chronic illness, longevity, and neurodegenerative diseases.

Jennifer is a Bend native, and when she is not reading new books on the microbiome or listening to podcasts, you’ll find her at the park with her two amazing young boys. She can also be spotted on the hiking or cross-country ski trails with her husband or meeting friends at food carts.

James Southam MSN, FNP-C

James was fortunate to spend his first career as a Cross Country ski racer and represented the US in two Olympics, three World Championships, and as a 5-time National Champion. He was initially exposed to Functional Medicine while trying to figure out why he was getting sick so frequently during his skiing career. James needed to be in tune with his body’s systems to perform as an athlete. Through Functional Medicine, he addressed the underlying causes of his illness, even creating his recovery drink to meet his nutritional demands. As a result, he saw a resurgence in his performance culminating in the 2010 Olympics.

After skiing, he studied at Oregon Health and Science University to become a Family Nurse Practitioner. James is keen on helping people optimize their health, including helping athletes of any level strive to reach their goals through a foundation of health. He takes a personal approach to help patients achieve their health, function, and performance goals.

James still loves snow, outside the clinic, spending time on the trails and in the mountains, playing tennis (not on snow), and exploring the West with his wife and two children. He has stayed involved in skiing since his retirement through board positions with the Mt. Bachelor Sports Education Foundation, US Ski and Snowboard, and the US Olympic and Paralympic Committee’s Athlete Advisory Council.

Paige McAfee MSN PNP

Paige McAfee MSN PNP

Paige is a Pediatric Nurse Practitioner with a primary mission of helping children and adolescents thrive. She believes that children’s bodies are resilient and have incredible regenerative power.

After receiving a global health degree from the University of Washington, Paige’s nursing education began at Duke University. Upon graduating, she moved to Portland, Oregon, and spent years working as a neonatal and pediatric critical care RN. She continued to notice the reactionary pattern of critical care and felt a calling to address pediatric diseases more upstream. She attended Vanderbilt University and graduated top of her class as a Primary Care Pediatric Nurse Practitioner. She brings her pediatric primary care experience and pediatric ear, nose, and throat into her practice today.

As a nurse practitioner, Paige continued to notice a gap in treating the root cause of common pediatric symptoms. She believes in treating her patients as a whole, acknowledging that mental health, physical health, and the environment must all be addressed. Paige completed functional medicine training through the Institute of Functional Medicine and mindfulness-based stress reduction training through Brown University to gain more tools and knowledge to help patients. She loves working with families of children experiencing symptoms such as gut disorders, allergies, eczema, mood and mental health changes. She is constantly amazed and inspired by the adaptive nature of children’s bodies and how they have the power to feel better!

Wellness can sometimes be overwhelming, with information overload from books, podcasts, and health trends. Paige believes that health for our children is getting back to the basics and keeping it simple. Eating real foods, playing and moving our bodies, creating positive connections with others, and finding joy in daily life. It does not need to be rigid and full of impossible rules to follow in our busy lives!

Amanda Fitt MS

Amanda Fitt, MS is a CNS (Certified Nutrition Specialist), Certified Integrative Nutrition Health Coach, and is finishing up the last requirements needed to become a Licensed Dietitian Nutritionist. Amanda is extremely passionate about helping individuals with their digestive health, metabolic health, sports nutrition, as well as women’s hormones and fertility through nutrition.

Amanda’s interest in functional nutrition developed after feeling pretty let down by mainstream healthcare throughout her teens and 20’s. After growing exhausted of conventional medicine and surface level “solutions”, she knew there had to be a better way. Upon experimenting with her own nutrition and eating habits during her undergraduate years, Amanda became fascinated with the science behind food, how it could be manipulated to improve one’s health, and how the food we eat impacts virtually every system in the human body. She then went on to earn her Masters in Science of Applied Clinical Nutrition so she could help others reap the benefits of therapeutic nutrition.

In her free time, Amanda loves to be outdoors: as an avid rock climber, mountain biker, and trail runner, she understands how adequate nutrition is essential for being able to engage in the activities you love for years to come. When she’s not playing outside, you’ll likely find Amanda baking up some tasty goodies in the kitchen and spending time with her partner, Josh.

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.

Megan B.

I came to SHIFT because my cholesterol has been getting too high for my age (38). Laura is very thorough - we talk through every angle of my health and goals - from diet, to sleep, to hormones, post-baby pelvic floor, you name it. She has so much knowledge, she catches many things that I didn't realize I was doing that are helping me move closer to my goals. She's a great listener, and take as much time as need - no rushed doctor appointments, never late. In just a few months of being more aware of little tweaks I can make I'm making progress getting that cholesterol number lower, and I feel excited and optimistic about the next step of our plan.

Heather J.

I have been seeing Laura Evans, NP, for a few months and already the experience with SHIFT compared to my (former) primary care physician has been astounding. Laura takes her time to listen and ask questions to get a holistic understanding of health issues so she can help treat the cause and not just the symptoms. I have already had significant improvement for a number of health issues that other doctors simply ignored when lab results came back as “normal” even though I was still feeling terrible. I really feel like I have an advocate in Laura, and that she is looking for a cure and not just a cover-up. It feels great to be taking natural supplements instead of harsh pharmaceuticals. I’m so grateful to have found SHIFT and Laura!

Vanessa L.

I've been seeing Jen at SHIFT for a couple months now and have made major improvements to my health, even helping me quit my diet coke addiction of over 15 years. Very kind and understanding as well as knowledgeable. Highly recommend this establishment.
