Dr Viehman was extremely thoughtful and knowledgable.

i was terrified this would be another experience of not being heard, and that would seem to be my official dead end. I was beyond relieved and thankful this doctor actual listened to me, prioritized testing and left nothing on the back burner or unnecessarily postponed things that were important to me like everyone else has. I feel a little more hopeful now and confident I'm at least more on the right track to potential answers or the appropriate solutions.

I met Dr. Viehman when I had my hip revision and learned of an infection in the hardware and again for my last visit at Falk, both times, he showed an extreme concern for my well being. I will gladly keep him as my ID dr.

Dr. Viehman was thoughtful, thorough, helpful, and respectful. He listened and communicated exceptionally well. He had clearly read my records, had informed and well-placed questions, and came up with a thoughtful diagnostic and intervention plan. I left the appointment feeling both hopeful and well cared for.
