Incredibly poor bedside manner. Dismissed my concerns and was patronizing. Would not recommend him to anyone.

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!

His solution to thyroiditis was to prescribe Synthroid and send me out the door. Total waste of my time.
