Always comfortable with my care and treatment at Avera.
July 15, 2021
My Dr is very easy to talk to. He never makes me feel like only he knows whats best for me and listens to what I feel i need. He tries to get me help from other Doctors when he feels I need extra help. He listens to my concerns and tries to understand them. Sometimes I have an issue with one lady on the phone that frustrates me sadly.
July 10, 2021
Wouldn't ask for a different Doctor

Dr. Did a great job explaining everything to me.

Always treated with Respect and Professionalism.
June 20, 2021
Providing clearer instructions regarding the process for checking in for a lab visit. I also don't feel that the overall reason for my visit was thoroughly resolved. Initial testing didn't reveal any causes and rather than continue to investigate, I was just given a prescription for my symptoms.

Everything was great.

When I asked about weight gain, I received the standard- eat less, work out more. I already workout 5-6 days a week and feel like I eat like a bird. I wish my dr would have gone over my general concern more and given me some resources.

When I was seen by dr Bannwarth he was very intelligent and made me feel comfortable and that he cared about my illness. He was understanding and very helpful as was the nurse.
April 17, 2021
I planned appointment for vaccination as early as possible so I could get to work. Nothing else was needed other than the shot but I was called back 20 minutes behind schedule. Another nurse should have been able to step in to give the shot. Also, maybe confirm what type of shot is to be given with the patient before it is injected. Just to make sure that it is correct.
April 10, 2021

Dr. Bannwarth is by far the best primary provider I've had the pleasure of visiting with in the 40 or so years of my adult life. Do what evet it takes to keep him at this clinic.
March 30, 2021
Avera goes above and beyond to keep me improving with my heart health. From the moment I'm not feeling the best, until I'm I am on the road to recovery, everyone at Avera goes above and beyond. We have wanted to reach out and commend Avera for all they have done to support us during Covid. We could have never gotten through it all without the daily calls and care from the nurses as we fought Covid at home. Avera is to be commended for the care plan they had in ace from the moment this virus became a reality in South Dakota. We thank you so very much!
March 27, 2021
We came for a spot check and were politely told only enough time for extra worries. We made a future appointment with their help.
March 25, 2021

November 19, 2020
All is well.
November 14, 2020
Dr. Bannwarth has great bedside manner. He is personal and makes sure everything is understood. As a health care professional myself, I appreciate good patient care and kindness.
November 14, 2020
For a first appointment, I was met with genuine concern and support for my health and well being.
November 14, 2020
The Prairie Center and it's staff are the crown jewel of the Avera System. I cannot say the same about the hospital or some of the clinics. I have recently considered other places for care in other health areas outside your system. If I feel that way you can be assured others do. Think about why.
November 13, 2020
Good Experience !!!

Appointment was on time and I was out quickly, very efficient.
October 06, 2020
I'm almost 62 years old and have seen many GP DR's in my life and Dr. Bannwarth is the best in my experience. Please do whatever it takes to keep him at your facility. I feel guilty sometimes for the amount of his time I take asking questions, but he's always willing to explain until he's sure I understand. He is golden.
October 02, 2020
Dr Bannwarth was very helpful
October 02, 2020
Awesome care
September 25, 2020
I appreciated being able to be seen the next day. The large boil that was drained was quite painful but not an emergency. I felt so much better after the procedure. Also, I am a nursing (RN) student, and asked that Dr. B. educate me on the procedure. I learned a lot, which I'll apply in my future nursing practice. Thank you, Dr. Bannwarth!
September 25, 2020
Good visit with doctor and all staff!
September 24, 2020
This was the first time I met Dr. Bannwarth and he was nice and somewhat thorough; however he did not pick up on a couple of symptoms that I had. His nurse or assistant did not seem "on the ball". She was going to take my blood pressure a second time and had promised to come back in the room in a few minutes to allow me to give a urine sample and never returned. My husband had to go out of the room to get her. I got the feeling that she was new to the position or just not very tuned in.

Dr. Bannwarth does a good job communicating.
