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.

Even though he was behind with me, he took plenty of time with me and I could see he was doing everything in his power to give me options! I was there for a second opinion and he gave me drawings which were helpful. I was very impressed. knowledgeable and super friendly.

Dr. Ludwig was the 2nd colo/rectal surgeon that I consulted, but it was my first experience with Froedtert & Medical College of Wisconsin (F&MCW). The prior healthcare provider that I went to left the impression that they were heavily focused on profits. Their staff were stretched too thin, and they made mistakes. Don't get me wrong, I'm actually a proponent of for profit healthcare because it provides healthcare consumers with choices. I didn't feel comfortable in my prior teams care so I sought out Dr. Ludwig. I did a lot of research on Dr. Ludwig including reading many independent patient reviews. My experience was consistent with those reviews. He was knowledgeable and respectful. He took the time to fully explain my condition as well as the trade-offs with different treatment options. In addition, the staff around him were very professional. I felt much more confidence in him and F&MCW compared to the prior surgical team that I visited. The criticisms that I've read about Dr. Ludwig tended to center around wait times, and wait time was even part of this survey. From my perspective, the stakes are high with the conditions he treats, and I'm perfectly fine having to wait in order to get the quality of care that he provides.

Would have liked him to explain what and why he was doing a procedure also if I had some questions to add. He drew a picture of my problem and didn't give me any hope or helpful therapy.

I believe that there is always room for improvement in all occupations and organizations. Therefore, I did not rate an overall 10.

*Dr. Ludwig was very careful to explain my condition and the risks of surgery to correct the problem. He is very methodical and spent more time with me than I would have expected. I would highly recommend him to any of my friends, relatives or associates.

I understand being in oncology is difficult but waiting an hour and a half to see the Dr is too long. A patient has better things to do with their time than wait to see a Dr. I understand I am not extremely sick but I think if the dr is that behind the receptionist should call the patients to let them decide if they want to come later. I could have worked another hour instead. this is not the first time I have waited this long.
