About Me

Geoffrey Shouse, D.O., Ph.D., is a hematologist-oncologist at City of Hope® Cancer Center Duarte, where he also serves as an assistant professor of lymphoma. 

Drawn to pursue a career in hematology and oncology by an early interest in molecular biology, Dr. Shouse went on to earn a doctorate in cell, molecular and developmental biology from the University of California, Riverside, followed by a medical degree at Western University of Health Sciences in Pomona, California. His postgraduate training included a residency and fellowship at Loma Linda University Medical Center in California and an advanced fellowship in stem cell transplantation and cellular therapy at City of Hope. 

Dr. Shouse’s research is centered on finding new therapies that may lead to a cure for lymphoma. He serves as principal investigator on several clinical trials exploring innovative approaches to treatment, including cellular therapies, molecularly targeted drugs and immunotherapy. He also leads studies aimed at improving treatment outcomes for older patients, who may be more vulnerable to the side effects of lymphoma treatment. Additionally, he is dedicated to developing clinical trials that expand access and increase participation among underrepresented populations. 

Known for his deep commitment to patient care, Dr. Shouse is a valued and integral part of the City of Hope team and a compassionate, patient clinical provider.

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.

"Seems caring and listens well. However as I was driving home it occurred to me that he did not give me even the quickest exam. Did not listen to my heart, feel my lymph nodes etc. And I have lymphoma. He only looked at my test results. I have never had a doctor NOT examine me. That did not sit well with me."
