Education & Experience
Dr. O’Neill is a board-certified osteopathic family medicine doctor fellowship-trained in integrative medicine.
Her practice combines conventional medicine, osteopathic manipulative treatment, physician acupuncture, functional medicine, and lifestyle medicine to provide individualized, whole-person care.
She earned her medical degree from A.T. Still University's Kirksville College of Osteopathic Medicine, the founding institution of osteopathic medicine, and completed residency training through Maine-Dartmouth and the University of New Mexico. She later completed a fellowship in Holistic, Integrative and Pluralistic Medicine at Lawrence Family Medicine Residency, along with physician acupuncture training through Harvard Medical School. Additional certifications include functional medicine, cranial osteopathy, and yoga instruction.
Dr. O'Neill has contributed to medical education and scholarship throughout her career. She is published in the Integrative Geriatrics text of the Weil Integrative Medicine Series, has participated in educational initiatives of the Institute for Functional Medicine, and has served as a guest speaker for both the Institute for Functional Medicine and Integrative Medicine for the Underserved.
As an educator, she has taught integrative primary care to medical residents, nurse practitioners, and U.S. Army Special Forces medics. She currently teaches in the physician acupuncture program at the University of New England College of Osteopathic Medicine and serves as a clinical preceptor for the Family Nurse Practitioner Graduate Program at Western Carolina University.
Her work has extended beyond traditional clinical practice. In collaboration with the CDC and Partners In Health, she helped implement a Fruit and Vegetable Prescription program on the Navajo Nation and has volunteered medically in China, Haiti, and Peru.
Over more than two decades in medicine, Dr. O'Neill has cared for patients in urgent care, primary care, adolescent health clinics, Veterans Health programs, and Indian Health Service clinics.
This breadth of experience, spanning patients from infancy through advanced age, informs her thoughtful and comprehensive whole-person approach to care.
Dr. O'Neill believes that health is shaped by the complex interactions among body, mind, environment, and community. Her approach combines evidence-based medicine with thoughtful attention to each patient's unique circumstances, values, and goals. By partnering with patients to identify the factors influencing their health, she seeks to create practical, personalized plans that support lasting well-being.
She was delighted to make the mountains of Western North Carolina her home in 2018 after many inspiring and formative years of medical practice and travel. She enjoys both the quiet—and not-so-quiet—moments spent with family, immersed in nature, and in the company of two lively ginger cats.
