About Me

Wai K. Park, DO, chose to become a physician because of her deep desire to promote health, offer support and guide patients and their families through challenging times. As a clinical geneticist at City of Hope® Cancer Center Duarte, Alongside her deep expertise in genetics and cancer prevention, Dr. Park also has a dedication to patient care: her medical journey began as a registered nurse, a role in which she spent 10 years caring for patients in a wide variety of clinical settings. 

Inspired to take her medical knowledge further, Dr. Park earned a science degree from California State University, Los Angeles, followed by her medical degree at Western University of Health Sciences in Pomona, California. She then completed her residency at Kaiser Permanente in Fontana and went on to specialize in clinical genetics and genomics through training at the University of California, Irvine. 

Dr. Park believes that genetics is a powerful tool in the fight against cancer and that, by understanding the genetic changes that make someone more likely to develop certain cancers, we can offer early screening, reduce risk and tailor treatments to each individual patient. 

Fluent in both English and Burmese, Dr. Park was inspired to join City of Hope after a loved one received care there.

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.
