FUNCTIONAL MEDICINE APPROACH
Functional Medicine is a progressive, yet naturally intuitive approach that considers your emotional, physical, and nutritional well-being to uncover the root causes of illness. By addressing these underlying factors, we work to restore balance and support the body’s ability to heal itself. While this approach can benefit nearly every medical condition, it has shown particularly positive results in treating diabetes, fertility issues, thyroid disorders, chronic fatigue, obesity, and autoimmune conditions.
At Integrative Medicine Northwest (IMNW), our goal is to provide compassionate, personalized care that meets you where you are on your health journey. We believe that true wellness is built on a trusting and collaborative relationship between patients and their medical providers. Our team is dedicated to bringing knowledge, experience, and individualized support to help you achieve optimal health.
At IMNW, we take a comprehensive and integrative approach to healthcare, offering a wide range of services to support your well-being. Whether you are seeking primary care, complex medical care, pediatric services, dietitian counseling, hormone optimization, IV therapy, or mental health support, we are here to partner with you in achieving your health goals.
We are committed to empowering our patients with the tools, treatments, and expertise they need to take control of their health. Our providers work closely with you to develop personalized care plans, ensuring that your unique needs are met with compassion, expertise, and a holistic perspective.
We look forward to building a meaningful, long-term relationship with you and being an integral part of your healthcare team. Your journey to better health starts here.
What We Provide

Primary Care
Integrative Medicine
An integrative approach to primary care combines traditional medical practices with complementary and alternative therapies to treat the whole person—mind, body, and spirit. It emphasizes a patient-centered approach, focusing not just on diagnosing and treating illnesses, but also on preventing them and promoting overall well-being.

Functional Medicine
Functional medicine focuses on identifying and addressing the root causes of disease, considering genetic, environmental, and lifestyle factors. It aims to restore balance through personalized treatments like diet changes, supplements, and holistic therapies.
At our clinic, our functional practitioners (Johanna Golke, PA-C, and Dayna Turner, FNP) utilize muscle testing as part of their approach to assess the body’s response to foods, substances, or therapies.
Muscle testing is used to:
-
Identify food sensitivities or intolerances
-
Test for toxins or allergens
-
Evaluate responses to supplements or treatments
-
Detect imbalances in energy or organ function

Mental Health
Caring for both the mind and body is essential for optimal health. Our Psychiatric Mental Health Nurse Practitioner, Dana Jacobson, integrative approach combines pharmacological and non-pharmacological treatments while considering factors such as nutrition, exercise, spirituality, environment, and community in promoting overall well-being. Dana values integrated care and collaborating closely with other members of the team. She is trained in trauma-informed, person-centered care, putting the patient, who is truly the “self-expert,” at the center.
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 Golke
Physician Assistant
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, and 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 themselves. 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.

Dayna Turner
Nurse Practitioner
Dayna is a Nurse Practitioner and an Integrative Health Provider who is focused on finding the root cause of her patients’ health problems. Her personal history of health struggles lead her through a journey of exploring and utilizing natural medicine for healing. Her story has become her specialty! She grew up in the Great Lakes region of Canada in a small farming community where playing in mud and dirt was her thing. She did several summers taking underprivileged children on 10-20 day canoe trips in Northern Ontario. That is where she first began her journey with Lyme, mold and parasites. Dayna became a Nurse Practitioner with the intention of practicing medicine God’s way. Pharmakeia is not her style! She prefers to use natural curing remedies found in nature. Dayna is an advanced Muscle Tester who has been trained through many different modalities using the autonomic nervous system with frequencies, photons, wavelengths and resonance. These modalities for healing is an ancient practice that scientists are still trying to unravel. Dayna believes that these qualities of nature were given to us by the Creator for our benefit of health restoration and to demonstrate His glory!
When she is not at the clinic, you can find her at Beacon Hill, mountain biking or in the woods hiking and chatting with birds.

Dana Jacobson
Dana has been a nurse practitioner for 13 years and has practiced in primary care, internal medicine, hospice, and palliative care. She managed chronic diseases for adults
and frail elders in their homes, and she has worked with acutely mentally ill adults in inpatient psychiatric units. She has also helped train our next generation of providers, teaching undergraduate and graduate nurses at Gonzaga University.
With a life-long interest in physical and mental wellness, Dana has always been involved in sports and outdoor recreation. From growing up in a rural community to having a house call practice in downtown Seattle, Dana has a passion for working with
people from all walks of life and in all settings. After her initial career in the business world, it was Dana’s volunteer experience as a rural firefighter and EMT that ignited her passion for caring for others, leading to a career in nursing, where she could have a
greater impact on preventing illness.
Dana holds undergraduate degrees from Whitworth University and Seattle University, and she graduated with nursing degrees from Seattle University and Gonzaga University. She is licensed as an Advanced Registered Nurse Practitioner (ARNP) and is nationally certified in Geriatrics and Psychiatric Mental Health (Lifespan) by the American Nurses.

Dana believes that caring for both the mind and body is essential for optimal health. She takes an integrative approach by utilizing pharmacological and non-pharmacological treatments and considering how other factors such as nutrition, exercise, spirituality, environment, and community play a role in our function. Dana values integrated care and collaborating closely with other members of the team. She is trained in trauma-informed, person-centered care, putting the patient, who is truly the “self-expert,” at the center.
It has become increasingly difficult for patients to know where to turn for accurate and safe information at a time when healthcare has become fragmented and difficult to
navigate. Dana is excited to join Integrative Medicine NW, working closely with patients, clinicians, and staff in a unique model of care that seeks to address the whole,
multidimensional person—treating the full spectrum of physical, emotional, mental, social, spiritual, relational, and environmental influences that impact an individual’s health.
Dana continues on her own wellness path as well. A mother of two grown children and six grandchildren, Dana lives with her husband on a regenerative farm. As they work to improve the land while raising their own meat and produce, they provide a home for numerous rescue animals. Having personally experienced illness, injury, trauma, chronic pain, and metabolic challenges, Dana understands the importance of addressing both the physical and mental aspects of health. She is excited to partner with you on your wellness journey.
