I was considering leaving john hopkins practice until I started seeing dr. Caldera. He is the best dr I have ever seen and the only reason I stayed. He cares about his patients takes time to research medical issues, and is always thoughtful and prepared for every appointment. I have met a lot of drs and no one compares to him. Your other drs in Hagerstown could learn a lot from him. Also his assistant [staff] is awesome as well. She cares about her patients and its obvious they are going out of their way to give 100%.

Dr. Caldera Colon is very knowledgeable and explains everything in layman's terms. He also responds to my "MY Chart" all the time. He answers my questions and reviews my test results in a timely manner. When asked, I refer my friends to his practice.
