Image of Dr. O'Neill

Jennifer O'Neill, M.D., F.A.C.S. is Board Certified by the American College of Surgeons. For the past 7 years, her practice has specialized exclusively in benign and malignant diseases of the breast. She founded Arizona Breast Consultants with the specific intention of giving her patients a higher, more comprehensive understanding of their disease processes administered in a compassionate, caring manner.

Dr. O'Neill attended the University of Tennessee Medical School (Memphis) graduating in 1987. After attending the University of Illinois, Peoria for her Surgical Internship, she completed her General Surgery residency training at Michigan State University in 1993. The next six years were spent in private practice in rural Virginia performing the entire gamut of general surgery.

At this time in her life, she was married with two small boys. Her husband was finishing a residency in General Surgery at The University of Virginia with the intention of going on to practice trauma/critical care surgery. Knowing there was a strong possibility of practicing in a metropolitan setting in the future, Dr. O'Neill entered a Hepatobiliary Fellowship at the University of Virginia to expand her training.

However, three months into this advanced training, her mother was diagnosed with terminal breast cancer after having had early stage disease many years before. This life-changing event lead to Dr. O'Neill shifting her focus to treating breast diseases, and it has been her passion from that moment on. She finished the next 9 months studying breast surgery exclusively and subsequently accepted a faculty position at Vanderbilt University prior to moving to Arizona.

Her practice was developed under the "motto" that all patients will be treated the same as her own family members would be treated, giving only her very best to each and every patient.

Professionally her CV includes:

  • Fellow, American College of Surgeons
  • Member, American Society of Breast Surgeons
  • Committees: Ethics Committee, Education Committee, reviewing fellowship programs for accreditation
  • Member, American Society of Breast Disease
  • Committee: Vice Chair, Consensus Committee with multiple publications
