Dr. Ela is so warm and friendly. She greets my children with a smile and knows just what to say to them to put them at ease. She is so patient and takes time to explain what's she's doing. She is THE best pediatric dentist I have encountered! I can't recommend her enough!

I had the most amazing experience at the dentist! Dr. Leslie Gazdeck and her dental assistant Gupreet not only did an amazing job with my teeth, but made my visit so fun and easy! As a teenage girl, the dentist is not typically an experience I would be excited to attend but after my appointment with them my view has completely changed! With their amazing attitude and their super fun music I'm now looking forward to going to the dentist! 10/10 would recommend!!

Dr. Ela is an amazing doctor! She is so warm and welcoming! My kids absolutely love her bubbling personality and have no issues going to the dentist when I tell them we are seeing her! This office is extremely convenient in the TriBeCa area! I can't recommend them enough!

Dr. Ta's office is sleek, modern and has all the cutting edge technology under one roof. Dr. Ta provided a complete picture throughout my son's time wearing orthodontics. Her front office staff and assistants are both warm and professional offering personalized service with a smile. But the real gem of a find is Dr. Ta. Not only is she an exceptional Orthodontist, she is always available for a consultation or question. She made me feel like she really cared about my son's bite and smile.

We love going to see Dr Ta! I have 3 children so I am there alot and I can happily say that I never wait more than 5 minutes. That is an amazing feat which I greatly appreciate. Dr Ta is also amazing with my youngest child, who upon entering her office is always crying because she is afraid, Dr Ta ushers her over to the chair and explains every little details and before we know it, we are all, on our way! Exceptional practice and wonderful treatment, what else do you need, call her!!

I walked into Dr. Ta’s office, some 40 years after having braces as a teenager, with crooked bottom teeth, zig-zagged top teeth and a lop-sided bite that left me prone to clenching on one side. I discovered, through the process of wearing braces as an adult, that I am highly sensitive and unable to tolerate much discomfort. It is through Dr. Ta’s deep well of patience and sensitivity along with her brilliance and ingenuity that I walk out today with a much wider, straighter, more even and balanced smile. I am grinning ear to ear. Thank you Dr. Ta!
