    Dr Barrera is the most knowledgeable and kindest physician I know.
    29-Jul-2018
    Dr. Barrera is a compassionate and kind person who has a great memory and is very inclusive in his consultations with his patients. My wish would be that he was a little more holistic or integrative in his practice. The support staff needs refining and that is why I cannot wholeheartedly recommend the pratice.
