Miguel Gomez discovered roots had partially plugged a toilet drain line and took care of the problem. What impressed me was not just the ease with which he diagnosed the problem and then fixed it, but his professionalism, his helpfulness when I was removing the toilet, and most of all, the obvious pride he took in his abilities. What a nice young man. At 21 years old he demonstrated a maturity well beyond his years. He is a model for your other technicians!
