Stay away!!!! I was in braces for 4 years before I left him and went to new orthodonist who reviewed my case and said it should have only took 18 months to have fixed, which is what Dr Rinaldi said it would take in the first place but because I paid monthly for tightening (after I paid the initial fee that other orthodonist said would have been his total cost) he prolonged the straightening to get monthly payments from me!!! He ripped me off for thousands don't fall for his scamming!!!! Consider yourself warned!!!!!
