I can't say enough good things about Dr Kampourakis in Mattituck. He took over Dr Boukas business…read morewho was also a great dentist.

I had an extremely disappointing experience here and feel compelled to warn others. This place is…read moreowned by a private equity firm, and it shows. They're clearly more interested in profit than patient care. I came in with an issue, and they immediately told me I needed an implant and multiple surgical procedures that would have cost thousands. Something didn't feel right, so I went to a trusted private dentist for a second opinion. He fixed my tooth in 30 minutes with no implant, no surgery, no drama. I will NEVER return here and strongly discourage others from going. If you do end up here, do yourself a favor and get a second opinion. This place is all about upselling and fear tactics, not actual care. Total scam artists.

Do everything you can to avoid seeing Dr. Bridget Petersen. She will shame you for having Medicaid…read moreand essentially make you feel worthless that you should be happy being seen by anyone, don't dare ask questions or stick up for yourself with subpar treatment or she will gaslight you by saying, "You're being rude. Sit down." I was treated like a child by her for simply trying to clarify what a treatment was. I had been told different things by different doctors at this practice and when I told her what she said was different than Dr. Erickson she retorted, "Well she's not here anymore." Her whole tone and delivery is condescending. Dr. Petersen is the reason I am switching offices and will no longer come here. Patients shouldn't be shamed for what type of insurance they have with her nasty tone and elitist attitude. Do better. Learn some bedside manner.

1-Star Review…read more Absolutely disappointed with this office. After 10 years of being a loyal patient, they refused to see a mom for appointment because of daughter's bill that had already been sent to collections--which legally, they can't collect on! Worst part? They never even reached out and waited weeks until the appointment. They just lost not only me but my entire family and extended family as patients. Unprofessional and unacceptable. The staff is not professional at all and no care for human life as they acted disgraceful when told of a recent death. Appalling service

I had been coming to my annual check ups in this office for long time and I used to enjoy to see…read morethe desk personnel with a big smile and professional attitude. Patrice is my hygienist for the past few visits and she is great. I can't say the same about the desk staff anymore. The only doctor today is Dr Trapani and seems like he has a difficult case with one of his patients and everyone has to wait without having any of the office staff apologizing for the delay and explaining what's going on. It's time to have at least 2 dentist at all time in the office. I don't come just for x-rays and clean up. The most important part of a dentist visit is the evaluation to keep up with a healthy teeth. I am very disappointed that I a have to advocate for myself to want to be seeing by Dr Trapani, otherwise I was just going to be dismissed until my next appointment. That's unacceptable for a loyal patient.

I spoke to Dr. Zeifman at a first Friday in Mattituck (evening street festival in the summer), and she said to call the office. I was so impressed with the office staff and the overall office! It's beautiful! Seriously, I wish this was where I did my orthodonture! And they are very mindful of costs. They give you all your options upfront and no pressure. I was able to get an appointment and get the retainer replaced the same week! Living out on the North Fork of Long Island, exceptional care is so hard to find, but Dr. Zeifman and her office absolutely provide it! Thank you so much for taking care of me and my smile!!!
