What our patients say

  • Great facility, great service. Dr. Reilly was very detailed in explaining my dental health and suggestions!

    Whitney B. - Portsmouth, NH,

  • I was pleasantly surprised at the well decorated, state of the art office I had walked in to for my exam. Dr. Logan was extremely pleasant, even on the phone when I booked my appointment. When we went over the x-rays/photos he had taken, he was realistic and didn't try to persuade me to get any work done, because I didn't need any. It is very comforting to know that I am cared about as a patient, not just a payer source. I would definitely recommend Dr. Logan. I drove all the way to Greenland from Rochester, and I'm glad I did!

    Stacia J. - Rochester, NH,

  • Very clean and modern office and equipment. Dr Reilly does a great job explaining your options, procedures, and costs. You can tell he wants his patients to feel comfortable and confident when they are there. Very happy with my experience here and will be keeping him as my dentist.

    George C. - Dover, NH,

  • I switched to Logan Reilly about 6 months ago - was looking for a dentist trained (and current) with all the latest technologies, knowledge and skills. He delivers on all three. Added bonus was the candid discussion on treatment plans and their costs (both what I would pay and what was covered through my insurance) - I've never had such a detailed understanding of pros/cons of treatment plans and their costs.. Highly recommend.

    Ernie S. - Exeter, NH,

  • I've never been fond of going to the dentist and Dr. Reilly is the first to make me feel truly comfortable in the dentist chair. I have never had a more thorough examination before in my life. I also appreciate that he takes the time to talk to you and answer any question you might have. He has completely changed my view of dental care. I've recommended Dr. Reilly to several clients at the spa I work at and will continue to do so. I can't wait for my next appointment in a couple weeks!
