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.
