    When I first met Dr. De La Llata I was very impressed with his knowledge. He was very helpful with what I was there for. I was very satisfied with his concern about what I was telling him about my problem. I wish I could see him every time I go, but sometimes I see the PA. I have no complains when I see Mr. Hernandez. He has been very helpful too. I understand that he has a lot of other people to see.

    Me gusto su forma de consultar muy profesional y sobre todo estudio mi caso antes de entrar a consultarme, así como estuvo abierto a todas las preguntas que le hice contestando perfectamente a cada una de ellas, además su trato personal es amable, y pone atención a cada detalle durante la consulta, en fin me gustaría que siempre me consulte el, porque muchas veces no esta, ´porque atiende en oros lugares, yo prefiero consultar cunado este porque me siento muy contento de que estan atendiendo mis padecimientos
