About Me

“What brings me the greatest joy is building a bond of trust with my patients during some of the most difficult moments in their lives,” says Aziz Ahmad, M.D., a surgical oncologist at City of Hope® Glendora. A highly respected surgeon known for his expertise, kindness and his sense of humor, Dr. Ahmad has been described by patients as “an angel” and “a surgeon’s surgeon.” 

Dr. Ahmad specializes in colorectal cancer surgery, but he also treats patients with cancers affecting other parts of the body, including the stomach, liver and pancreas. He sees patients at City of Hope’s Glendora and Rancho Cucamonga locations. Before joining City of Hope, Dr. Ahmad spent eight years treating patients through the Palo Alto Medical Foundation, one of the Bay Area’s largest health care networks. 

After earning his medical degree at the Chicago Medical School at Rosalind Franklin University, Dr. Ahmad completed his internship and surgical residency at Lenox Hill Hospital in New York City. He went on to complete a fellowship in surgical oncology at the John Wayne Cancer Institute in Santa Monica. He came to City of Hope to work alongside a team he describes as deeply committed to their patients. 

“If I can’t help someone directly,” he says, “I know I’m surrounded by colleagues who share the same passion and will do everything they can to help.”

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.
