What Our Clients Say About Us

  • "My daughter loved it and she had a great time on her first visit. Dr. MacDermott is very friendly. He explained everything to us in step by step details."
    - Gabrielle B.
  • "I really can’t say enough about how wonderful our visit was. From the cleaning, to Dr. MacDermott, even the billing... you guys really provided a wonderful experience. Many thanks see you soon."
    - Andy D.
  • "I wasn’t looking forward to my 3 year old’s first dental visit. Dr. MacDermott was professional, thorough and informative. He put both my son and myself immediately at ease, and made what could have been a very unpleasant experience incredibly fun and enjoyable. My son loved his first dental exam and we’re looking forward to our next checkup. I only wish he took grownups!"
    - Juliet F.
  • "I take both my daughters to Dr. MacDermott and he is absolutely amazing with them. In fact, my 2-year old cracked a tooth and required extensive dental work. Not only was he great with her, he was extremely skilled, giving us excellent advice and ultimately building her a perfect replacement tooth that is indistinguishable from her real ones. He has a real way with children and is also great with parents. He is truly best pediatric dentist we have come across and I cannot recommend our experience with him more highly."
    Dana W.
  • "While watching Dr. MacDermott work with my 4 year old, another parent was amazed at how relaxed my daughter was. The credit goes to you for the excellent service you provide. The atmosphere at your office makes kids feel at ease and your staff is excellent when it comes to interacting with children. My daughter likes her dental appointments. I thank you for that."
    - Vanisha J.
  • "Dr. MacDermott was great!!! My daughter had two teeth removed in August and she did great. I was more nervous then she was. I am so happy with Brownstone. I will tell everyone I know. Thanks again."
    - Grace M.
