Integrative medicine is a healing-oriented medicine that takes account of the whole person (body, mind, and spirit), including all aspects of lifestyle. Conventional medicine centers around disease identification and management most often with medications, devices and surgeries. Integrative medicine responsibly uses other complementary and alternative therapies where scientific evidence of safety and efficacy are available. The basis of integrative medicine is the therapeutic relationship between the provider and patient, while making use of all appropriate therapies, both conventional and alternative, when appropriate.


Most commonly, lifestyle modification and natural therapies are the preferred option of treatment, however, conventional medical treatments will be recommended when natural therapies are not enough. Integrative medicine physicians do not limit themselves or their patients to single treatment options. Natural therapies include:


Exercise & Lifestyle Modification

Stress/Relaxation Techniques

Herbal Medicines

Dietary Supplements

Functional Lab Testing


At Grand Rapids Natural Health we provide a unique, integrative, and collaborative approach utilizing our medical director, Dr. Johnson, MD and our Naturopathic Doctors.

Our medical director, David Johnson, MD, has been board-certified in internal medicine and cardiology with additional expertise in integrative medicine through fellowship training in integrative medicine at the Arizona Center for Integrative Medicine. He has more than 20 years of clinical experience. He specializes in integrative medicine and preventive cardiology.

Our Naturopathic Doctors are board certified in naturopathic medicine and have attended four-year, year round medical schools, recognized by the US Department of Education.  Currently, Michigan is a non-licensure state, therefore our NDs hold licenses outside of Michigan and work with our medical director in order to provide the level of care they have been trained to do.

Your care may be overseen by one of the providers above or could be a combined approach between multiple providers.

These services are also supported by practitioners from other disciplines, including:

Nutritional Health Coaching

Mind-body Medicine through  Energy Medicine

Manual Medicine such as Massage Therapy and CranioSacral Therapy

Traditional Chinese Medicine, such as Acupuncture and Herbal Medicine

IV Therapy and Vitamin Injection Services


We often hear from our patients that they have had labs run by their doctors, but nothing showed up or they were told nothing is truly wrong. Our primary approach is to find the root cause of disease by using the tools listed above. If, however, we wish to dig a bit deeper, our doctors use integrative lab tests that look at the whole person, analyzing various aspects of health, including nutritional status, gastrointestinal health, dietary sensitivities and much more. Get to know a few of the companies we use below. 


A 15-minute complimentary meet and greet consultation is where we recommend you start to be referred to the appropriate doctor, or team of doctors, for your individualized care. Use the system below or call our office at 616-264-6556 to book.
