I am new to Hamilton and unfortunately chose Dr. Olivieri as my dentist. I had only one visit and that was enough. I found him to be arrogant, callous, disrespectful and demeaning to his employees. IN MY PRESENCE. I have seen a pig with better manners! I have no insurance and even though I had a full set of X-rays from my previous dentist, which could be transferred, he wants to have another full set done by him. It was obvious he was trying to set me up for expensive treatment. NOT recommended!
