Colleagues describe him as "Dr. Grillo was highly instrumental in saving me from severe kidney treatments another physician had ordered; he immediately had certain catheters removed, restored normal blood pressure and allowed certain food and nourishment back into my daily diet. He saved me from misery. Not only is he an excellent physician, he makes his patients feel very comfortable, by explaining why he prescribes, changes or cuts certain medications. He is sorely missed."
