They are not professionals to begin with, they are more focused on collecting the money from you not on the service. It seems they do not care if you comeback or not. They charge me $200 in co-pay and $1500 from my insurance just for cleaning, they haven't done a good job, bad customer service and after a month or two they send me $265 additional payment out of nowhere. I got robbed I will never go back to this place as well as recommend it anyone I know.
