Sandy M.Holtsville, NY64Oct 28, 2023Non judgmental, wanted to know how the situation happened and now trying to come up with a plan on how to fix it . None of the "you should have taken better care of your teeth" or any of the stuff dentists say when your teeth are not in great shape. Thank you for being different and understanding.

Jodi T.Commack, NY092Mar 15, 2023My primary dentist for over 20
Years retired and recommended kreitzberg dental. It is very stressful changing dentists. The transition was so easy. Staff is super kind and right on the ball with scheduling and billing. Both dr Kreitzberg's are friendly and kind. Jeannie has been my hygienist for many years and was hired from my previous dentist which made the transition easier. Wouldn't hesitate to recommend Kreitzberg dentistry.Helpful 0Thanks 0Love this 0Oh no 0Business owner information

Thank you, Jodi. We appreciate you taking the time to write a very nice review. We know it's difficult to see a new dentist and we're proud that your previous dentist suggested you visit us. We love meeting new patients and friends and look forward to your visits for many more years to come! We're thrilled to have Jeanne with us and we're even more thrilled to meet new friends such as yourself! Thank you for taking the time and such a nice review. See you soon!
Harry B.Brooklyn, NY5582Nov 22, 2022Moved out to Commack and needed a new dentist so I did my research online and saw this practice with top notch reviews and now I know why!
Dr Dustin Kreitzberg and Mary Ann were amazing! Thorough job, thorough examination, excellent bedside manner by both. Super friendly staff and a clean and very well run office.
Very happy to have become a patient here. Would recommend to anyone in the area!Helpful 0Thanks 0Love this 1Oh no 0Business owner information
