Dr.Mann provides exceptional care to his patients. He provided visuals when explaining treatment and options. He is not afraid to take on complex cases and coordinates with other surgeons if needed. He encourages questions also.

Words cannot express the gratitude and respect I have for Dr. Mann. To say he is the very best does not say it all. He explained my cancer in language a layperson could understand. I met with him twice before the surgery and he put my wife at ease about the surgery. He is the very best at what he does and would not hesitate to recommend him. He saved my life and for that I will be eternally grateful.

My experience with Dr. Mann and his staff was very reassuring and it gave me the courage to go forward with my procedure. Major surgery to remove a large mass is a daunting experience. It is fair to conclude that a favorable outcome would cast a positive glow on my experience with Dr. Mann but when it comes a life saving procedure like a major surgery, a positive outcome is all that matters.Major surgery is no picnic. It is scary, painful, there is a scar and I hope to never have to go through anything like it again, but Dr. Mann and his staff helped me through it with their expertice and care.Dr. Mann is a very accomplished and serious man but he also smiles and has a warm side. It is apparent that his staff respects and adores him and I am comfortable in reccomending his services to anyone in need of a surgeon in his specialty. There are no guarantees when you are facing a major health challenge and surgery always has its risks but one thing you can do is try to get the best Surgeon… possible. I hope and pray that Dr. Mann can help you as he has helped me.

Dr. Mann is a wonderful doctor who takes the time to tell you all you need to know about the issues you are seeing him for. He answers all your questions and more in a way you understand w/o feeling in the dark. He did my whipple surgery 5 years ago and to this day I am doing awesome. I walk out of his office after a follow up feeling happy and relaxed because the outcome is positive but if I have an issue he makes sure all is well.
