About Me

Christina Haeyoung Yeon, MD, MHM, is a medical oncologist and hematologist and the regional director for City of Hope’s San Gabriel Valley locations.

Dr. Yeon has been caring for patients in Pasadena, California, since 2004, offering leading-edge treatment options for all types of adult cancers, as well as both non-cancerous and malignant blood disorders. She has a particular interest in breast cancer care. In her role as regional director for the San Gabriel Valley, Dr. Yeon oversees six locations and works closely with team members to ensure high-quality care across many specialties.

Beyond her clinical and leadership responsibilities, Dr. Yeon is actively involved in several committees at City of Hope.

She has also been elected by her fellow doctors to serve on both the medical executive committee and the board of directors for the medical group.

Dr. Yeon moved to the United States from South Korea when she was five years old and grew up in Riverside, California. She completed most of her education at the University of California, Los Angeles, earning a bachelor’s degree in biochemistry and her medical degree there, then completing both her internal medicine residency and her fellowship in medical oncology and hematology at the same institute.

Dr. Yeon has been part of the local community since 2005. She lives in La Crescenta, California, with her husband and their three children.

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.
