Doc & PA were awesome.
This was a brief checkup, asked for by my GI doctor. However, I have a history of colon cancer, surgery, and follow up care by Dr. Ludwig and his staff. I have always felt like I was in the best care, and always recommend them to those needing that information.
They made you feel very comfortable in all respects
Dr Ludwig and his staff are a blessing to the medical field
The Dr seemed to know what he was doing and what he was talking about. I feel I am ln good dands with both the Dr and the nurses.
Dr Ludwig was awesome!
Very good visit and treatment. Would like to schedule future appointments right away.
Excellent care provided by everyone I dealt with, especially Dr. Ludwig.
The professionalism and knowledge is without a stellar but in addition they seem to genuinely care.
He was very good at explaining things in terms that we could understand.
I thought it was cool that my Dr called me himself and his assistant.
Dr. Ludwig has always been very attentive to my concerns and questions. He goes the extra mile to explain things I don't understand, and because of this, I have come to put my complete confidence in him. He is a skilled surgeon and doctor who cares about his patients, and I have been blessed to be under his care, starting with him as my second opinion, during my treatment and surgeries(2), and even now as I continue my follow-up exams.
Was very impressed with the way Dr Ludwig explained everything. I was a little nervous but he made me feel better with his explanations.
It was very good and answer most my concerns. Dr. Ludwig explains very well , what my option and the choice to my treatment.
I appreciated Dr. Ludwig taking time to show me my x-ray and the explanation with it. He was not rushed. He answered all my concerns and questions patiently. I would recommend Dr. Ludwig to all my family and friends.
Dr. Kirk Ludwig is a great doctor, a great surgeon, and a great man.
Amazing doctor. Wish I would have know 2 years ago.
All good! Love Fr Ludwig and staff!
Nothing but good to say about the whole team
Dr. Ludwig and his team provide the best of care. Their skills and knowledge are unsurpassed by anyone. From my first visit to my continued care, my confidence has never wavered. He went into great detail of what to expect and has been spot on in every aspect of my battle with cancer.
After my visit I was comforted with the care and felt my bp went down. Thank you.
Dr. Ludwig was very detailed in his explanations. He explained everything in terms we could understand.
A very comfortable experience.
I have always had a good experience with this clinic and especially with Dr Ludwig and his staff.
We have the most utmost respect and confidence for Dr Kirk Ludwig and his team. Im a patient of an oncologist at CSM but once referred to Dr Ludwig years back I trust him with my life!
From my first appointment (for a second opinion), to my ongoing post- surgery check-ups, I feel confident and satisfied in placing my trust and care with Dr. Ludwig.
I was very pleased with my overall experience! Thank you for giving me such great care. I have a few more appointments and happy to be going to Dr. Ludwig.
