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 provides state-of-the-art, individualized care for every patient in a lovely office environment with friendly and responsive staff. The office is well-run, organized, efficient and approachable. Dr. Ta excels in both brains and heart! We have referred many patients to her office and will continue to do so.

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.
