Dr. Caldera is the BEST Doctor I have ever had. He is thorough, knowledgeable, compassionate and truly cares about his patients. Doctors like him don't exist anymore and Johns Hopkins is beyond fortunate to have him on your team. He should be recognized for his excellence as a doctor and for his customer service as a role model for Johns Hopkins.
