Patient Reviews
Jun 17, 2023
Dr. Hahn is an extremely knowledgeable surgeon. I had a very large hiatal hernia where most of my stomach was up in my chest and putting pressure on my heart and lungs. He did an incredible job and now I can eat normal foods. Any body with these kind of problems so go see him. He explained things very well, he is very friendly and knowledgeable.
