Dr. Krob has a pleasant personality and adequately explains everything. His receptionist, however, is not very friendly. His dental assistants that do the adjustments are not very competent, so it's a good thing he checks behind them. One visit, an assistant had to redo my wire too many times that I was in the chair for 45 min. Even with all that time the wires cut into the sides of my mouth constantly and I had to remove the wire from being engorged in my cheeks everyday. My mouth had welts and painful sores that made it difficult to sleep.
