“This was simply the best dentist experience of my entire life. Everything was so clean, so courteous, so welcoming - the whole thing felt much more like a spa day than a visit to a dentist. Dr. Ko only sees one patient at a time so I felt completely attended to with care, transparency, and communication. I only went in for a cleaning and Dr. Ko unprompted helped remedy a separate dental issue (a broken bar on my lower teeth) easily, successfully, and without charge. A rare dentist visit I could describe as LIFE CHANGING! I cannot recommend her anymore. ”

Dr. Ko was extremely thoughtful, thorough, and professional. She was engaging throughout the appointment, always clearly communicating what she was doing, why, and asking if I had questions. The space is immaculate and the whole experience was great. I would recommend her services to anyone.

The best dentist I've met in NYC! I needed a new dentist because my insurance changed, so I found her on Zocdoc. Today was my first dental consultation with her. She's extremely knowledgeable, professional, thorough, and kind 10/10. I will be back and will recommend her to friends!

An incredible doctor and dentist!! She is truly the best dentist I have been to in my life and felt completely safe and well treated. Was very worried about my wisdom tooth and had scary experiences outside nyc but with Dr. Ko, the procedure was painless and completely fine in her fine hands. She truly cares about each and every patient and has the best bedside manner I have ever experienced. She is exceptional.

Dr. Ko is the best! I have been a patient of Dr. Ko for the past 5 years, since I moved to the area. She is very sweet and attentive. She was also genuine and suggested avoiding invasive procedures when it wasn't necessary. So glad I chose this practice.

Dr. Joy is the best dentist I've ever seen! She was very thorough and clear in what she would be doing, going through with me. What she saw on X-rays and exams, and was very gentle in the exam and cleaning. Attentive to my questions and clear in recommendations in what to watch and improve on. Highly recommend!
