I was very impressed with Dr. Castillo. He answered all my questions and we had discussions and went over medication and I came home with prescriptions that I was very satisfied with. Very, very happy. I'm glad that he's my doctor.

I'd like to get my bloodwork done at Clinical Pathology. They never have trouble drawing my blood and don't hurt me. Would that be possible? Thank you.
