Welcome to


Integrative Medicine NW

A refreshing and inspiring approach to Health and Wellness


"Functional Medicine" is an emerging and yet refreshingly natural and common sense approach that takes into consideration your emotional, physical, and nutritional status and seeks to find to root cause of illness.  We then work to re-establish balance and wellness for the body to heal itself.  While nearly every medical condition could benefit from this approach, we frequently see successes in the areas of diabetes, fertility, thyroid, chronic fatigue, obesity, and autoimmune conditions. 

At Integrative Medicine NW, we are driven by our passion to enhance your overall health and wellness. Our philosophy is grounded in a holistic approach to medicine that understands the importance of physical, mental, emotional, social, environmental, and spiritual health in achieving optimal wellness. We pride ourselves on being observant, great listeners, and empathetic partners so we can identify the root cause of the issue and create a comprehensive treatment plan tailored to your unique needs. You can trust us to guide you every step of the way on your journey to optimal health.  Our aim is to educate and connect with each patient to empower you to take charge of YOUR health, with support from our team.

Improving others' quality of life through preventative health care continues to be a priority of John's career. His passion for finding the most credible, evidence-based, efficient & effective approaches for empowering people with long-term change led him to finding the most foundational, transcendent, and synergistic best-practice intervention for long term behavior change--MI. He also continues to keep his individual MI approach sharp through his practice as a Lifestyle/Integrative Medicine Dietitian—both with individual counseling and group facilitation.

Peter was born in Phoenix Arizona, and his interest in the medical field started at a young age.  His dad was a family physician, and much of his childhood was formed as he watched his dad run his own medical clinic. Patients would frequent their home, and they would sometimes stop by a patient's home on the way home from church.


They moved to an area north of Spokane when Peter was 12, and he made the transition to country life, learning to drive a tractor and falling in love with farming and nature. He ended up starting and operating a cabinet and furniture company for several years until he and his wife made the decision to get out of the industry and follow his passion for medicine.


He completed training as a paramedic with the intention of pursuing PA school and graduated from the Physician Assistant program at University of Washington in 2015.


He practiced for 3 years in family medicine in Spokane and then transferred to a company that offered urgent visits to patients' homes. He continued in that position, adding additional skills and knowledge in the acute care setting until starting his own medical practice in 2020.

He has completed extensive training through "The Institute for Functional Medicine" and has been practicing functional medicine principles since the beginning of his medical career in 2015.  Peter is passionate about "practicing medicine" in a way that puts the patient first and seeks to discover the root cause of disease and then get to work supporting the body to heal itself.  

Johanna is a Physician Assistant and Integrative Health Practitioner with a passion for wellness, holistic health, and helping others. She started her medical career working in an Interventional Pain Clinic which served as the driving force into discovering the world of functional medicine. She treated hundreds of patients with chronic health conditions and pain not improving with conventional medicine and pharmaceuticals. She started researching anti-inflammatory and autoimmune protocol diets, supplements, and other modalities which only further her passion for holistic health.


Johanna transitioned to working in Neurosurgery where she enjoyed working with a variety of patients. Unfortunately, she started to struggle with her own chronic health issues. She knew she didn’t want a “band-aid” approach to her health issues after seeing so many of her own patients struggling, so she started a journey to discover the underlying root cause to her health issues. This involved removing several different toxicities including mold and its mycotoxins, glyphosate, parasites, heavy metals, and eventually discovering Lyme Disease and its coinfections. Johanna continues her path to health as it can be quite a journey to reach optimal health and vitality.


As Johanna has experienced her own health struggles, she understands the frustrations of patients dealing with their own health issues and just not feeling like yourself. So, if you are tired of being told your labs are normal, using medication as a band-aid for your symptoms, and are ready to change your lifestyle, she is here to help guide you along your journey, treat your body as a whole, and help you take control of your health.
