Dr. Helfner and her team are nothing shy of INCREDIBLE! Every single person in the office is amazing! I used to avoid the dentist at all costs but stumbling upon Dr. Helfner and her team I’m completely comfortable and confident with the treatments and procedures I have done. Dr. Helfner treats each patient like a friend with genuine care and concern, her staff does the same. I’ve been to other offices that are friendly but when you walk in the door it’s just like any other office. Dr. Helfne
