About Me

Arya Amini, M.D., grew up in Southern California and is deeply grateful for the chance to care for people in the community he calls home. 

“Taking care of my fellow Californians at one of the nation's top cancer centers is one of the greatest honors of my life,” he says, describing his patients as “some of the most courageous and resilient people I’ve ever met.” 

A nationally recognized expert in radiation oncology, Dr. Amini is the chief of thoracic radiotherapy at City of Hope® Cancer Center Duarte, where he provides expert care using a wide range of advanced radiation therapies, including image-guided radiation therapy (IGRT), brachytherapy, stereotactic radiosurgery (SRS) and stereotactic body radiation therapy (SBRT)—all designed to target tumors more precisely and reduce side effects. 

Dr. Amini is also a dedicated researcher who studies treatment trends, looks for ways to improve outcomes using combined therapies and identifies disparities in care. He leads clinical trials in lung, skin and head and neck cancers, and has earned several research grants to advance this work. He has authored more than 100 peer-reviewed studies and received numerous awards for his contributions to cancer care, including being named one of the city’s top doctors in 2020 according to Los Angeles Magazine. 

Dr. Amini earned his medical degree at the University of California, Irvine, where he also completed his internship. Then, he pursued a radiation oncology residency at the University of Colorado in Denver. Dr. Amini values a team-based approach and is excited to collaborate with expert colleagues across specialties at City of Hope to provide well-rounded, patient-centered care.

Patient reviews
The patient ratings and comments on this page are obtained from an external Press Ganey® outpatient survey provided to all eligible City of Hope patients within one to two weeks of their treatment occurrence. Raw data from the answers to the survey questions about our physicians are calculated by Press Ganey into a one- to five- star rating. In the spirit of transparency, all patient comments are posted as written by the patient, whether they are positive or negative. We only exclude comments if they are deemed to be slanderous or libelous, contain profanity or vulgar language, or do not relate to the patient's experience with the doctor involved. As a result, the comments are the views and opinions of the patients surveyed and are not endorsed by, and may not necessarily reflect the opinion of, City of Hope.

"Dr. Amini is an exceptionally kind, gentle, and attentive physician. From my very first visit, he responded swiftly when he saw how much pain I was in, taking immediate steps to help relieve my discomfort and ease my worries about being in the mask or the machine during treatment. What stood out most was how accessible and approachable he is. He even replied directly to one of my questions through the patient portal, which made me feel supported and confident in the process. He explains just the right amount - enough to inform and reassure - while allowing space for healing and trust in his care. Dr. Amini is surrounded by an incredible, respectful, and professional team. You can sense their high regard for him in the way they work together and care for patients. The other doctor he works closely with [...] was also outstanding, and the entire staff was impeccable in their understanding and compassion. In every interaction, I felt truly seen and cared for - not just as a patient, but as a person. I'm deeply grateful for the kindness, skill, and humanity that Dr. Amini and his team bring to their work."
