Poor "bedside" manner. Treated like cattle coming through his office. My son waited for 2 hours yesterday and was treated as though he were an inconvenience. (Had I known he was going there I would have warned him to run far away.) He was treated roughly which only served to heighten my son's fear of dentists. I will ask that my dentist not recommend Dr. Koelliker again. He was rough and not at all sympathetic to his discomfort. When I had extreme pain following his treatment he was "oh well, it's the weekend and I cannot call in anything for your discomfort. You'll just have to bear it. I do not recommend him at all! I have never written a review on line before but I want to let all out there know what they will experience here. BEWARE!
