    Jun 16, 2017
    Dr. Casis is always very attentive and informative when I meet with him. He thoroughly explains his diagnosis and his treatment recommendation and never seems rushed when I have additional questions for him to answer. Dr. Casis is friendly and easy to talk to and understand and his staff are always very helpful and nice. I definitely would recommend my family and friends to see him!
