"Dr. Nagle is the best GI surgeon in Chicago. He's extremely nice and works with amazing office staff. He made sure I was well taken care of in the hospital and came to visit me twice with a big smile on his face! he meets with patients very soon after surgery for a post-op class with a dietician. He adresses all the risks and lets you know right away if you're a high or low risk and what surgery will give you the best results. "
