About Me

Patients appreciate the kind and thoughtful approach that Sagus Sampath, M.D., takes at City of Hope® Cancer Center Duarte. One patient shared, “A great doctor, easy to talk to, answers any and all questions plus gives you information you need to know, never makes you feel rushed, and makes you feel like he really cares. And my treatment was successful.” 

Dr. Sampath is a board-certified radiation oncologist and associate clinical professor in the Department of Radiation Oncology. He has been honored by his peers as a “Rising Star” in Super Doctors and named a Top Doctor by Pasadena magazine every year since 2014. 

When he’s not caring for patients, Dr. Sampath enjoys playing South Indian classical music on the violin and competing in tennis as a USTA level 4.0 player. He also speaks Spanish.

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.
