Cancer is not a good thing. The Dr and staff are very supportive. I need that. They have talent and they have personality. They smile and don't act like robots. I pray for their safety while treating others. Froedtert has many heroes working at their facilities. God bless them all!!!

Dr. Mooney is honest with his answers to my questions. I feel he is always optimizing the best approach to my particular health issues. I also feel like he treats me the same as he would his own family. I have utmost confidence in my treatment from him.

Dr. Mooney is an oncologist. I was just a patient. I've been years out from my dx for some time now. I rated him the way I did as he's the one that deals with cancer day in and day out, giving people news they never want to hear, seeing them at their sickest and on death's door yet still remains encouraging and hopeful for others.

Dr. Mooney was thorough in preparing us for what life will be like in the different rounds of chemo. I loved how he waited for me to finish writing things down before speaking again.

The care I have received from Dr Mooney and the entire staff has been great. When they are taking care of my needs I feel that I have there complete attention. I realize that they have many patients but I have never felt blown off passed over or ignored. I thank Dr Mooney and the staff for that.

Jan. 7, 2020
Dr. Mooney clearly stayed after hours to see me because of the urgency of my condition. He never once looked at the clock or made me feel like he wanted to get going. The office was clearly closed when we walked out of his office all the staff was gone and he walked us to the front door and was so kind

Caring / passionate
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.

excellent provider gave more than one option to my health condition. felt he had read my chart before entering the room and had a plan for me.
Oct. 2, 2019
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.

Aug. 15, 2019
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.
