Amber Warren, PA-C

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. Outside of her career, Amber enjoys mountain biking, skiing, and anything in the outdoors with her three boys and husband.

Karen Callagy, PA-C

Karen received her Bachelor’s degree in Kinesiology from Pennsylvania State University in 1997. After working in Physical Therapy, as a PTA for several years, she went on to obtain her M.S. in Physician Assistant Studies at Arizona School of Health Sciences in 2005. She began her PA career in Family Medicine, eventually transitioning to Urgent care, as well as a brief stint in Oncology. In all these settings, she began to realize that prescribing medications was not enough to make patients better and in many cases only perpetuated the problem. In her personal life, she was dealing with family members with autoimmune diseases that conventional medicine could not help, because diet was never addressed. After discovering the Institute of Functional Medicine in 2014, there was no turning back. Not only has she helped her own family but innumerable patients with the help of IFM. She continues to work towards her IFM certification, specializing in thyroid and gut health. Karen firmly believes in “mind, body and spirit” and that each of these aspects must in balance for her patients to achieve their maximum health potential. She immensely enjoys going on the journey to wellness with her patients and believes it “takes a village” to accomplish this, ie. Nutrition staff, life coaching, and in some cases counseling. In her personal life, she enjoys outdoor activities with her husband and 3 children, on the mountain where they reside, with their bunnies and Bernese Mountain Dog.
