I am comfortable in the dentist's chair, but if you are someone that gets nervous, I recommend you get to know this office. There are TV's (with the option for headphones) in the rooms if you need a distraction and all the dentists, hygienists, and assistants will talk you through everything. Sarah performed my cleaning and she was more informative than some dentist I have met in the past."

We are all very pleased and impressed with the professional skill and personal character of Dr. Helfner and all of the people she chooses to work with. I have experience with dental practices in several states and Dr. Helfner is special. It is very difficult to strike a work / life balance that allows a dental team to be at their best at all times, but Dr. Helfer's practice is the paradigm for professional effectiveness combined with concern for the individual."
