Provider could not give an answer besides they believed I may have cancer, but ran no tests and sent me on my way with no answers. Nor did they set me up with ent. Left the room as fast as he had arrived. It took a total of 5 minutes the provider had spent with me before leaving. He made an assumption without knowledge and left me in tears and fear. The nurse was the best part of my visit.

Everyone has been wonderful I'm extremely pleased with our quality of care we've received from Avera . Thank you again!
September 21, 2021
I like that the doctor was willing to try me on a lower dose of medication and offered different treatment options, not just "This is what you have to do." He considers the patient's preferences as a factor of treatment and that's part of the reason I go to him.
