    I have been seeing Dr Helfner for 26 years and have followed her from when she just started in a…read moreclinic to her well established office in Commack. Her office is always clean and she cares about the esthetics. Her staff is always very nice whether in person or on the phone. Dr Helfner is not an alarmist and is very caring. She does what she has to do in order to ensure an optimal outcome. She listens to your concerns and genuinely cares. I trust 100% of what she says in regards to my teeth. 26 years later and she has never steered me wrong. I've met Dr Curro a few times and also the hygienists and I have nothing but good things to say. If you aren't a patient yet, you really should go. Shoutout to Doreen who is always great to talk to. They have pretty good hours that I can make work around my busy schedule; nights and weekends. The parking lot can definitely get pretty packed at times but that would be my only slight issue. Overall, I definitely recommend this practice and Dr Helfner. I felt very safe going there during a pandemic. They took the proper precautions to keep everyone safe.

    If you want a superhero to do unnecessary dental work on your mouth Dr. Philip is for you!

I guess she has the superpower of x-ray vision. There was also talk about replacing old crowns and bridges, although not told directly to me. This is the worst dental experience I have ever had which has resulted in my loss of trust in this practice. Gives the appearance of doing unnecessary work just to make money.
