Our Philosophy

IWG is the ultimate healing solution to get well and stay well. The owners, Dr. Nick Carruthers and Dr. Nicole Rivera, are both chiropractors and functional medicine doctors who studied in the Bay Area of California. While practicing chiropractic in Seattle, WA, they realized that the evolution of healthcare must unite a mind, body, and soul approach to achieve a healthy, sustainable lifestyle.

Many of their patients had pain that stemmed from inflammation from their diet. This sparked the desire to continue their education of functional medicine based nutrition that utilizes blood, hair, stool, and neurotransmitter testing, among other analyses. Dr. Rivera is a functional medicine physician specializing in chronic conditions such as diabetes, GI issues, autoimmune disorders, hypothyroid, adrenal fatigue, hormone imbalances, and other conditions. IWG also offers detox programs and luxury retreats.

The doctors believe in a very different chiropractic experience. They perform a full body analysis with an emphasis on neurological function before working on any individual. This is unlike what you may have experienced with traditional chiropractic care. The typical office visit consists of full body chiropractic to the spine and extremities, active release muscle therapy, exercise therapy, kinesiotaping, and neurological balancing. The practice also offers Sound Wave therapy for severe conditions, tears, strain, sprains, fractures, and arthritis.
