Dr Leidner saved my life-literally! I am happy to report that was over 2 years ago. He is staying so on top of things that I know that if anything recurs he has 2 or 3 things in mind to do. That is very comforting to me. He is brilliant and surely goes the extra mile for me and all of his patients . He Is the best.

Franz Cancer Center providers are amazing. The whole staff including nurses and doctors are top of the line, in addition to being warm and welcoming. I am newly diagnosed with cancer and feel completely supported and confident that I'm getting the BEST care available....truly beyond what I could have imagined prior to my diagnosis. With all the complaining that goes on regarding health care, I can't fault this clinic in any way. They seem to go beyond just meeting a person's basic physical needs. The social and emotional needs are addressed and handled with compassion, respect, and kindness.

Dr. Liedner is a great doctor who presents great amounts of information succinctly. He is very knowledgeable and shares his knowledge, answering questions, explaining things well and in terms I easily understood. This visit, however was scheduled before my most recent test results had returned and was basically, "your tests look good. You won't need to see me again, and good luck". He said I would not be charged for the visit.
