How likely are you to recommend Dr. Calnon?

(Select your rating)
Dr. Calnon was the cardiologist on rotation when I arrived at the ER for pericardial issues. I was 7 months pregnant at the time, and have a preexisting heart condition. Dr. Calnon took considerable care and attention to the matter, using both intelligence and great bedside manners. Very thorough and knowledgeable.
