    How was your appointment with Dr. Barrera?

    Jan 18, 2023
    I've been seeing Dr. Barerra since 2005 and have nothing but fantastic things to say about him. I had brain cancer in 2005 and I have every type of "ologist" in the book - Dr. Barrera is by far the best. He is patient and understanding, and actually listens to your concerns. He also is one of the few doctors who takes your feedback in high regard, because he knows that we know our bodies best. The fact that there is any review under 5 stars is baffling, to be honest.
