Dr. Samuel Ejadi joined Cancer Treatment Centers of America® (CTCA), Phoenix, in May 2021 as Chief of Medical Oncology. Board certified in medical oncology, Dr. Ejadi has extensive expertise in melanoma, advanced skin cancers, genitourinary cancers, sarcomas, neuroendocrine cancers and solid organ cancers.

When a close friend lost his father to the disease, Dr. Ejadi became committed to a career in cancer care and pursued his education with cancer in mind. He received a master’s degree in nutritional science from University of Illinois, where he studied the effects of diet on cancer and pharmacology and immunology in relation to cancer. Dr. Ejadi received his medical degree from the Robert Wood Johnson Medical School at Rutgers University in New Brunswick, New Jersey. During medical school, he received training in oncology and pathology at Memorial Sloan-Kettering Cancer Center and University of Pittsburgh Medical Center. He then completed transitional training in pathology at University of Pittsburgh before completing training in medicine at Johns Hopkins University School of Medicine. While in residency, he obtained additional training in clinical oncology and immunotherapy at the Johns Hopkins Hospital, Thomas Jefferson University Hospital, Beth Israel Deaconess and the National Cancer Institute, followed by an oncology fellowship in the Harvard Beth Israel Deaconess program.

After serving as a medical oncologist at Memorial Sloan Kettering Cancer Center in New York City, Dr. Ejadi moved west to the Mayo Clinic Arizona and later to the TGen Virginia G. Piper Cancer Center in Scottsdale. Just prior to joining CTCA®, he held several roles at the University of California Irvine, including co-director of the Melanoma Center and Associate Clinical Professor of Medicine.

Dr. Ejadi has been a pioneering member of early clinical trials of cell therapy and has served as local principal investigator or sub-investigator in more than 125 cancer trials.

Outside of CTCA, he enjoys exercising, working around the house and spending time with family and friends.
Patient ratings
Star ratings and comments are only available for medical, radiation and gynecologic oncologists. Gynecologic surgical offerings are not included at this time due to a different survey tool required to evaluate these services. CTCA uses a validated Press Ganey® survey, which captures patient experience feedback for the primary oncology services of chemotherapy and radiation therapy at our comprehensive care and research centers. Following industry best practice, star ratings and comments are only published for physicians with a minimum of 30 completed patient surveys.
