"I've been under doctor care for my disease more 30 years and essentially have had three gastroenterology doctors. My first doctor was terrible, the second I had for the majority of those thirty years and thought he was absolutely the best. Since his retirement I've gone to Dr. Carl Calandra. With two procedures under his care and a several visits, I am more than impressed with his "bedside manor" and his confident and focused explanation of my treatment. His suggestions have improved my overall life comfort. I'm so glad to be under Dr. Carl Calandra's care! thanks Doc!"

Both of these problems required procedures and hospitalizations. In addition, Dr. Calandra is a kind and down to earth person who took all the time necessary to explain any questions I had.
