From start to finish Dr. Hasal was caring, professional and exceptional when it came to my needs. He diagnosed my issue perfectly, took the steps needed to correct it and everything went flawlessly. He is a caring, skilled and professional surgeon. From start to finish Dr. Hasal and his team were amazing. I can best describe it as.. “poetry in motion.” I would recommend him to anyone. An exceptional surgeon, an exceptional experience. “5 Stars”

In my opinion, Dr. Hasl is one of the best surgeons around. He explained everything to me from what was wrong to what to expect after my surgery and recovery time. I have not had a issue since he took care of me. Thank you Dr. Hasl!!!

Dr. Hasl is meticulous and knows his stuff. He explained all of my issues clearly and concisely. His personable bedside manner is an additional plus. This was not my first colonoscopy and I am much happier with how Dr. Hasl handled the procedure. If you wish to place yourself in knowledgeable hands, he’s the man.
