This office is friendly but that's only because they are scamming you. Dr. Espinoza is mentally unstable and most his staff doesn't even like him.(one dental tech flat out told me) I have seen him come unglued when working with his dental techs as he deems them to be incompetent. They also charge you in advance for services then when you have a credit they refuse to refund it. They just insist you come back and get more work done. Total scam.
