Dr. Ali joined the faculty after completing a specialized fellowship in hematopoietic stem cell transplantation at City of Hope. 

Dr. Ali earned his medical degree from Rawalpindi Medical College in Pakistan, then began his postgraduate training with an internal medicine internship at Harbor Hospital Center at the University of Maryland in Baltimore. He then took on a residency at Loma Linda University Medical Center in California, where he advanced to chief resident and, later, served on the faculty for four years as an instructor and assistant professor of medicine. 

Seeking further specialization, Dr. Ali pursued a fellowship in medical oncology and hematology at the University of Texas Southwestern Medical Center in Dallas.

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.
