What Our Clients Say About Us

  • "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."
