Went for my six-month cleaning. Love my hygenist, Lynn. She is extremely thorough. When I'm done, my teeth feel squeeky clean. Dr. Andrew Frangella, my dentist, then comes in and gives my teeth a check for any cavaties or other issues. Happy to report no cavaties for quite a while, thanks to Dr. Biggiani's office ~ Commack Hilsl Dental Group. If you're looking for a dental group to keep you smiling, I 100% recommend Dr, Biggiani's office. You won't find a nicer group.

I went to this dentist office on a recommendation of a co-worker and all I can say is WOW! The office is state of the art, the dentists and dental hygienists are all knowledgeable and the staff is friendly. The staff made me feel comfortable right away and I did not have any pain when they worked on my teeth cleaning and scrapping all the plaque and tarter build up. I highly recommend coming here if you are in the need of a great dentist or even a cleaning. This is the only office I will go to from here on out.

I have been going to Dr. Biggiani's office for about 3 years. My dentist is Dr. Andrew Frangella and my hygienist is Lynn. Between the both of them, my teeth are the healthiest they've ever been. The office is equipped with the most up to date dental equipment and machinery. The staff is welcoming and friendly. They are terrific about letting you know when you need to schedule an appointment. Just a great dental group. Going to the dentist really doesn't have to hurt!!! 100% recommend!

MARY MCCARTHY
May 2017
I couldn't be happier that my fiance recommended me to go to "his" dentist's office (usually I'm the one who is always making the appointments!!). The staff are great! I always get taken on time (rather than typical doctor/dentist visits where you are spending more time in the waiting room than with the actual dentist/doctor) and the staff are very helpful. Angel is awesome! She is one of the dental hygienists. I first came to her after not being at the dentist in a few years (I know, gross) and she was both comforting and friendly despite my embarrassment and shame about not having gone to a dentist. She does a wonderful job as a hygienist!
NICOLE PECORELLA

I woke up with a toothache today. I called before the office staff was in, but my call was returned promptly at 9:00. They squeezed in an emergency appointment and I was seen at 10:00. I received excellent care- don't know if it will work- but at least we tried, and I know my options. I am very thankful that I am a patient of Commack Hills Dental Group. Professionals from start to finish!
