About Me

Cancer affects both the patient and their loved ones. My goal as your provider is to deliver optimal care using state-of-the-art technology in a multidisciplinary setting focusing on cure, comfort, and care.

- Amar Srivastava, MD, MPH

Dr. Srivastava was first introduced to the field of Radiation Oncology when his brother-in-law was diagnosed with a glioblastoma. This experience showed Dr. Srivastava that a cancer diagnosis affects both a patient and their family and taught him to experience cancer care from the patient's perspective. Dr. Srivastava was amazed by how a radiation oncologist can support both patients and families during one of the most difficult times of their lives and integrate advances in cancer care into the clinic to directly improve the lives of their patients. His favorite part of his job is telling a patient that they are in remission and/or have no evidence of disease after they have undergone an extensive course of cancer-directed therapies.

Dr. Srivastava was trained in Magnetic Resonance-Guided Radiation Therapy (MRgRT) during residency at the first center to utilize this technology in the U.S. and has over 4 years of experience with this technology. He is trained in MR-based adaptive radiotherapy, offered at The Oregon Clinic Radiation Oncology. Dr. Srivastava also brings extensive training in gynecologic and genitourinary high-dose rate brachytherapy, which is used to treat cervical/endometrial cancers and prostate cancer, respectively.

Dr. Srivastava enjoys living in Portland because of the unique and wonderful culture of the city. He also likes that the city is very walkable, has great restaurants, and is only an hour away from mountains, waterfalls, hiking trails, and beaches.

Outside of work, Dr. Srivastava likes cooking and experimenting with new recipes, spending time with his partner, their dog and cats, and taking in the city and surrounding nature.
