About Me

Kai Dallas, M.D. is a urologic surgeon at City of Hope® Cancer Center Duarte and the chief of urology at City of Hope® Antelope Valley. Dr. Dallas takes a whole-person approach to care, focusing not just on the physical symptoms of illness, but also on each patient’s emotional and mental well-being. He believes in listening closely to his patients and working with a team of specialists to create treatment plans that support a better quality of life. 

Dr. Dallas earned his medical degree from the Icahn School of Medicine at Mount Sinai in New York City, where he was honored for his achievements in research. He went on to complete his urology residency at Stanford University in California, followed by an advanced fellowship in genitourinary reconstruction and female pelvic medicine at Cedars-Sinai Medical Center in New York City. 

Dr. Dallas cares for people with a range of conditions including bladder issues, urinary incontinence, pelvic organ prolapse, urethral stricture disease and fistulas. In addition to his clinical work, he researches how health outcomes vary across different patient groups and explores ways that artificial intelligence can be used to improve diagnosis and treatment. 

When he’s not seeing patients, Dr. Dallas enjoys relaxing with family and friends and hitting the hiking trails with his dog.

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.

"Dr. Dallas listen to me describe what I was experiencing. So from this information he told me the treatment he recommended, so he came to this conclusion on what I said. I felt since Dr. Dallas is a specialist in this area I thought an examination by him would also explain his treatment recommendations. Dr. Dallas stepped out the room to get a paper for me to read about the treatment recommendations and left the room and the nurse came in, I said to the nurse I thought I was going to get an examination [...] So I want to make it clear Dr. Dallas did he thought was needed. I was the one left unsatisfied."
