Testimonials

  • "Exemplary, professional but still friendly and relaxed. I have been a client for over 20 years. Dr. McArdle has always had my best interest at heart and when advising treatment, gives a full evaluation of why with x-rays, films and photos. His care is remarkable. Over the years, he has established a team of warm and thoughtful personnel."
    Anne C.
  • "I have never had a better experience with any dental office, and I have enjoyed good treatment for six decades. All of the staff and Dr. McArdle are professional, friendly and informative. The offices are extremely pleasant and seemingly state-of-the-art. I would recommend them highly to anyone."
    Kenneth Butler
  • "Everyone was friendly, well-informed, and compassionate. I appreciated the time taken to help me understand not only what my cracked tooth needed, but also what the cost would be and when it was due. By far the most helpful and informative office I've been to in quite a while, and I'm happy to have found a great dentist!"
