Happy Patients

  • Sharon M., Bayside, New York
    I have been going to Dr. D for a few years now and he is by far the best dentist I have ever been to. He has convenient appointments for those who work, I never wait more than 5 minutes, he causes me NO pain and his staff members are friendly and very accommodating. He also see's me right away in emergencies. I recommend Dr. D to all my friends and coworkers.
  • Mary R., Little Neck, New York
    Dr D. is a great dentist. He is attentive, supportive, patient oriented, dedicated and reliable! Dr D and all of his staff make you feel welcome and part of their "family". I would recommend Dr D to everyone.
  • Bessie S, Douglaston, New York
    My entire family has been going to Dr D
    for years. A gentle touch, a great staff, and convenient hours. So many of my friends are also patients. Can't see myself being treated by anyone else. Give them
    a chance, you won't be sorry.
