Missy Frazelle, NP

Insurances Accepted

Missy Frazelle, FNP-BC, is an Integrative Internal Medicine Nurse Practitioner with a background in Oncology and Internal Medicine. She received her undergraduate BSN from the University of Arizona and her MSN from Loyola University Chicago. She holds a board certification from the American Academy of Anti-Aging Medicine and is a Functional Medicine Practitioner and a Bioidentical Hormone Replacement Specialist.

Missy is a native Phoenician who was born and raised in the heart of Arcadia. Her path to Integrative Medicine started when she discovered yoga to combat the stress of nursing school. She ultimately became a certified yoga instructor through Kripalu and went on to become an oncology nurse for seven years in stem cell transplant, radiation oncology, and oncology triage at MD Anderson Cancer Center in Houston and at Northwestern University in Chicago.

When she graduated with her masters degree she wanted to practice preventative/”root cause” medicine, where she knew radical health changes could be made. She joined the Raby Institute for Integrative Medicine at Northwestern (2017-2021) and then moved back to Arizona. 

Missy works to cultivate a unique approach to patient care, looking at the whole person to get to the root of disease and suffering. She combines a multifaceted approach– not just focusing on physical ailments, but emotional as well and the nature of how the body systems affect each other. Missy integrates her conventional western medicine training with eastern medicine/alternative modalities and offers guidance on inner healing from an embodied place. Integrating the mind, body, and soul is her goal, which paves the way for patients to live their best lives!

Missy is a Reiki Certified Practitioner and is involved in other energy work training to further serve her patients. She enjoys yoga, hiking, travel and spending time with her husband, two daughters, family and friends in the Valley.
