Dr. Bannwarth is a pleasure to visit because it's clear he cares by taking the time to hear my concerns and talk them through with me. Unlike some prior experiences at medical appointments, I have never felt rushed or ignored at an appointment with Dr. Bannwarth.

September 28, 2021
Very good run operation good help
September 28, 2021
Dr Bannwarth, his nurse, and the reception employees near the examination rooms are excellent and treat me with respect. The receptionists at the main area on 2nd floor do not come off as knowledgable and customer service isn't their main focus.
September 28, 2021
Appreciated All The People Who Cared For me! Look Forward To my Next Experience!

Wonderful personalized genuine care.
July 20, 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 20, 2021
Always comfortable with my care and treatment at Avera.
July 13, 2021
Wouldn't ask for a different Doctor

June 29, 2021
Dr. Did a great job explaining everything to me.
June 22, 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.
June 15, 2021
Excellent!!!! Very happy with my visit, Dr. Bannwarth did a great job of coming up with a plan of care for me!
June 15, 2021

May 25, 2021
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.
May 18, 2021

April 27, 2021

April 27, 2021

April 27, 2021
Waited almost an hour between seeing the nurse and doctor
April 20, 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 13, 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.
April 13, 2021
Team always exceeds expectations

April 06, 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!
