About Me

Patients often recognize Thomas P. Joseph, M.D., not only for his medical knowledge and research experience, but also for his attentive nature. It’s no surprise that when asked about his influences, Dr. Joseph points to a mentor known for compassion and a strong bedside manner — qualities he strives to bring to every patient interaction at City of Hope® Santa Clarita. 

Originally educated in India, Dr. Joseph discovered his passion for hematology while training at the Samuel S. Stratton Department of Veterans Affairs Medical Center in Albany, New York. He went on to complete a fellowship in hematology and oncology at the Medical College of Wisconsin in Milwaukee. 

For over a decade, Dr. Joseph has cared for patients in the Valencia and Mission Hills communities, serving in both private practice and at Henry Mayo Newhall Medical Center. He describes joining City of Hope as a natural decision, drawn by its reputation as a pioneer in cancer research and treatment. “It was an automatic choice,” he says, reflecting on the move to bring his practice and patients to a place known for innovation and compassion.

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.
