She has her undergrad in Nutrition Science from UC Davis and her Master’s degree in Nursing from MGH Institute of Health Professions in Boston, MA.

She first started looking in to functional medicine after many years of being disillusioned with allopathic medicine when her chronically ill patients rarely ever felt better with conventional treatment. She became fully committed to functional medicine after her father was diagnosed with stage 3 chronic kidney disease and was told he would be “monitored and then treated when it got worse- and it would get worse.” Luckily, he was not satisfied with that answer and came to her for help and guidance using her new found functional approach. 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.”  She believes our bodies are incredibly smart and protective and seeks to partner with her patients to find ways for their unique bodies to find the wellness and balance they once knew. She is an IFM Board Certified Functional Medicine Provider.

Outside of the office, Amy enjoys fitness, volunteering, gardening, traveling and all things outdoors. She and her husband moved to the area in hopes of enjoying all the wonderful outdoor opportunities Idaho has to offer.

Specialties include:

  • Gut
  • Hormones
  • Autoimmune
  • Headaches

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.

She loves the opportunity to get to know entire families and develop relationships with her  patients. While trained in western medicine she has long infused a whole person and natural  approaches to achieve best patient outcomes.  

Personal experience, specifically a mother who has responded poorly to the traditional western  medical approach, but used whole body approaches to find answers inspired Christa to begin  the process of understanding root cause medicine. The desire to help answer “why” is this  going on in the body and “how” to help the body heal has become a passion. The process of  teasing out each person’s unique puzzle is fascinating and rewarding, especially when you start  to see health restored.  

Christa grew up in the Treasure Valley, graduated from Meridian High School, earned her  Bachelor of Science in Biology from the College of Idaho. In 2008 she earned her Master of  Science in Physician Assistant Studies and Masters of Public Health from Touro University in  Vallejo, California.  

Outside of the clinic, Christa enjoys spending time with her husband and 3 children. You can  find them outside working on numerous projects with chickens, goats, rabbits, dogs, cats, and  gardening, or hiking and exploring the great state of Idaho.

She was a Division I college athlete, playing soccer while studying nursing. While she was a student athlete she earned her Bachelor’s of Science in Nursing at Gonzaga University in 2011. 
After several years as a bedside nurse, she felt the calling to advance her career. With a desire to focus on preventative medicine, and improvement of patient outcomes through education and empowerment, she went on and graduated with her Doctorate and Family Nurse Practitioner degree in 2021 from Gonzaga University. With several years working in various Emergency, Hospital, and Acute Care settings she learned early on that this approach of band-aid medicine did not align with her own life, values, and practice. She discovered the healing powers of lifestyle modifications and root cause medicine.
During her time as a student at Gonzaga and a nurse practitioner in the field she learned the meaning of ‘magis’. This concept means “to strive beyond the status quo”. She joined the team at Functional Medicine of Idaho to do just that. To dive deeper into disease prevention, optimizing wellness, and healing through dietary and lifestyle modifications.
