What an incredible place this is! We experienced not only exceptional care from Dr. Weinberger and the surgical team, but the entire staff from the initial consultation right up to today! Everyone has been very caring, and professional, and put both my grandson and I at ease with getting the necessary treatment he required completed. In addition to Dr. Weinberger both Ally and Shiloh helped us organize everything including dealing with a complicated insurance process. We could not be happier with our experience and recommend it to anyone with children who need dental care. To the entire team at Pediatric Dentistry and Orthodontics....BRAVO!

This is an amazing Dentistry place I can't believe the patience and care they have for children. The time they spent with my child really was just amazing they were so kind and caring. Ashley the assistant went above and beyond for my children especially my son who is in terrible twos and a little hard to handle at times he was having a tough day and she made him feel so much better that he didn't want to leave after spending time with her when at first he was reluctant to want to be there or anywhere at that time but he loved spending his time with her she's wonderful and knew how to handle any situation. The staff are all so wonderful they sure know what they are doing even front desk staff just so knowledgeable and eally care about my families well being I would recommend them to anyone. My kids and I felt safe and in good hands and it was a nice feeling knowing they really do care about the kids! I'm so glad I found them. Thank you so much Pediatric Dentistry
