Dec. 22, 2019
I'm happy with the speed in getting Mooney's office to call me on Thur and set up an appt on Fri to see him. Then Mooney's office called the oncology surgeon Fri after 3pm and they called me an hour later to set up an appt to see the surgeon. They all responded quickly.

He is an excellent physician (cancer). I wouldn't change to any one else. He is very caring and very helpful to me.
Sept. 29, 2019
The nurses/clerical staff are always fine to deal with, only this appt 3 THREE "nurses" techs came in to ask questions before the brief and unfriendly appearance of the doctor himself. And the scans had not been finalized so why wasn't appt set after test results were verified. This guy just has a very smug off-putting personality. Cancer is scary enough - he lacks any pleasant communication.

A huge Ten for Dr. Mooney. He genuinely cares and I feel great when I see him and we go through my lab work and discuss my progress. I feel blessed to have met with an angel person, who two years ago HIGHLY recommended Dr. Mooney, when I learned of this Stage 4 lung cancer that I ended up having. Ever since treatment, I feel amazingly better and look forward to each day, knowing that the treatments are working. Thank you to Dr. Mooney and his amazing staff at Froedtert, St Joseph's Kramer Cancer Center, West Bend, Wisconsin.

Dr Mooney and his staff along with the infusion room nurses are just wonderful. Cancer treatments give us a new "normal" and they understand this. The emotional state plays such a big part. We are all lucky to have people like this to help us.

I have seen Dr. Mooney very frequently while he has been treating me for my leukemia. He has formulated a treatment plan that has been successful, answered all my questions, reassured me when I was frightened and been available 24/7 if I needed him. I feel Dr. Mooney and the treatment team have played a very big part in the successful path to my remission. I am very grateful.
