Amber Warren, PA-C, Adult Functional Practitioner
Amber received her Masters in Physician Assistant studies from Midwestern University. She has completed the educational requirements for the Institute of Functional Medicine and will be fully certified in 2019. She started her career in orthopaedic surgery, appreciating anatomy and physiology, but ultimately had a desire to investigate the body as a whole. She eventually moved into the field of rheumatology, fascinated by the immune system and chronic disease management. It was in this space that she started to investigate the immune system’s interaction with environment, and the root cause of autoimmune disease- alterations in the microbiome. Passionate about nutrition, she started to implement “food as medicine” with her patients, and saw dramatic improvement in symptoms, and ultimately a reduction in the need for pharmaceuticals. A career in functional medicine has allowed her to incorporate everything she believes is needed to heal the body.

He is at is healthiest now, and she has never looked back. Amy has extensive experience in metabolic syndrome, insulin resistance, hormone imbalance, gut health, headaches, and autoimmune issues. She truly believes that food is medicine and that lifestyle changes are foundational for reversing chronic “dis-ease”.
