The office is nice and clean and they have separate rooms for sick children and for nursing moms. And they are always able to provide you with samples so you can try it first like formula or lotions. There is never a long wait time. They work perfectly on schedule. They are always able to give you a appointment on the same day if you have a sick child.

After that the office hours were minimal and I never got responces to my calls. The last straw was when the teenage receptionist called in an incorrect dosage of my child's medication! Thank goodness the pharmacist questioned it! I called and wrote to alert the doctors of this mistake and they never responded. Do not use them!

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.

Drove 1 hour in the rain to get my son to the office called them to advise I maybe a few minutes late. I get to the office at 6:13 only to be told, I'm late the Doctor will not see me. They changed my appointment to 5:40 without mentioning it to me(guess someone wanted to leave early) Then I rescheduled but canceled 2 days before the appointment was assured that the appointment will be canceled as I was not in NY as well as the future one that was scheduled for 8/3/2021. I spoke to Ann Donahue after speaking to the billing office she waived the fees but told me I was dismissed from the practice. Newsflash, my son was never treated there nor would I care.

Recently I contacted the office asking for a call back from Dr Serotoff, they ask for the reason, I explained. It involved needing a letter for school involving a chronic issue my child has had since diagnosed in 8th grade. I received a call from a secretary saying that the doctor won't write the note needed. I again asked to speak with her directly, they left her my message. 2 days later another secretary called me to repeat the first message. I am so angry that she doesn't care enough about a child she has treated for over 11yrs! I was told that since she hadn't seen her since her physical in August she wouldn't write the note. We will be shopping for a new doctor who actually cares!!

No problems getting an appointment and the staff was friendly and helpful. An EKG was done and reviewed y Dr. B. He said it was a non-functional murmur and no medication was needed.

I very highly recommend Dr. B, if a pediatric cardiologist is needed.
