It is sometimes hard to reach them by phone no one answers the phone sometimes and when I leave a message do not get a return call that could be improved other than that I really like Dr. Castillo and the staff they were very thorough and very efficient and I will continue being a patient there


Yes, in regard to the doctor there at the at the oncology hematology center, they were very, very good, was very, very compassionate and understanding. There was quite a wait line, but he's a busy doctor. So that's understandable. But he was diligent and... and precise in his conversation. I would definitely recommend him to my family and friends. He... he's definitely a caring doctor. There's no doubt about it. And he listens and thank you very much.
