Dr. McCullough is all that embodies an incredibly knowledgeable, professional, and empathetic care giver. If there was a CCF Physician of the Year - it should be awarded to him. I was very stressed and anxious about my condition. Dr. McCullough spent quite a bit of time with me to discuss the condition, treatment, and recent research that could benefit me. I cannot fully express how his positive and kind disposition made me feel at ease and confident regarding all future visits. The best physician I have seen.
