How likely are you to recommend Dr. Castro?

(Select your rating)
I honestly wish all doctors were like Dr. Castro. He treats you like he a friend or a family member. Spends time with you and answers all your questions. I don't like to leave reviews but I'll make an exception. I'm blessed to have been assigned by my insurance to Dr. Castro. My only gripe if anything are his MA that answers the phone, I don't understand why I have yet to find a clinic that has good medical assistants. Nonetheless, once you get past the phone calls you won't regret choosing Dr. Castro.
