I have felt very well cared for by Dr. Kirk Ludwig and his staff since first seeing him 3 1/2 years ago for my Colorectal Cancer surgery. I'm so thankful to be his patient and for all the expertise available at Froedtert Medical Center.

he took the time to listen to me and walked me through everything. And I'm feeling really good about the plan of action. I can't begin to tell you how pleased I am with this medical system. After surges through another medical system and continued issues. I'm starting to feel like we have a good treatment plan.

Dr. Ludwig changed my life. without his care, his expertise and over the top concern I would have had MAJOR surgery, chemo and radiation. His diagnosis and treatment plan saved me and changed my life. I owe him and his staff more then I could ever repay!!

The exam was very painful and awkward. I didn't feel the doctor's manner was very open when he initially came in the room and started talking with me.
Nov. 28, 2019
My care providers, both doctors and nursing staff, are always top-notch in the care provider as well as being personable. They make being at a medical appt actually enjoyable!

We waited over an hour to see the Dr. for my appointment. Once the Dr. came into the room he is very attentive to my needs. He read out loud from a card the reason I was there and what he needed to do to help me with my problems. He said I would be in the hospital for a few days after the surgery as this procedure is particularly painful. I have already receive phone calls from his staff members asking me questions about my condition.
