Dr. Killory was phenomenal from the very first visit. He was patient, knowledgeable, understanding and very thorough. Bedside manner was exceptional. He thoroughly explained everything to my husband and myself. Encouraged us to get a second opinion just to be sure we we’re making the right decision. Was always concerned about my care and follow up. He’s a GOLD star for his medical profession. Top notch.
