    Dr. Seyedin was excellent and explained things very well. He made me feel he was genuinely interested in my well-being and was there for me and that I am not alone in this journey to rid the cancer. He offered encouragement while also explaining pitfalls. He did not seemed rushed at all. I truly felt much better after meeting with him.

    Dr. Healy is wonderful, very attentive, and explained everything to me in such an admirable and thorough way. The nurses and technicians make the radiation process a pleasant experience, and everyone is extremely courteous. This is the best of UCI along with the breast cancer care team! Keep it up!

    Dr. Healy and all the people involved in my treatment were thoughtful and caring. I was informed of everything that was going to happen and how long things would take. They made sure that I was always comfortable and not cold in the cold room. They also made sure that I understand everything that was going to happen and how they were going to proceed. You have wonderful people working there!
