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!

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.

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.

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!
Alanna M. - Newmarket, NH
I was very impressed with Dr. Reilly and his staff upon my first visit to his practice. This is the first time I have ever had an experience where the dentist took the time to sit down with you and discuss your dental history and goals prior to the actual exam. When I first walked in I had expected to go immediately to the office and start the cleaning/exam. Instead he spent time with me in his office (sitting across from his desk) to determine the best possible dental care and review my expectations. WOW! I have never had such time and care taken for a dental exam! Plus the biggest coup is that he actually has my husband listening to him and improving his home dental care after only one visit! I would highly recommend Three Rivers Dental!
Victoria D. - Stratham, NH
Three Rivers Dental was the best decision I made for a dentist. The office is relaxing, the staff is friendly. Dr. Logan Reilly takes his time to make you feel comfortable and answers questions thoroughly. I was so impressed with Dr. Reilly as a dentist, I scheduled appointments for my whole family including our 6 year old-who was terrified of the dentist. Jack left with all smiles and even gave Dr. Reilly a hug when we left. Amazing experience!

I would highly recommend Three Rivers Dental and Dr. Logan Reilly. I had been going to another dentist for a number of years, and based on a recommendation, I went to see Dr. Reilly for a consultation. His office is very inviting and he and his staff go to great lengths to make you feel comfortable and welcomed. Dr. Reilly spent a good amount of time going over the dental issues I have, and explained things in great detail. He utilizes the most recent dental technology, and by doing so, he can do in one or two steps what would take multiple steps/appointments with other dentists. I really appreciate his calm demeanor and the great care with which he explains each step so you know exactly what to expect. If you’re looking for a new dentist, do yourself a favor and schedule an appointment with Dr. Reilly.
Ann C. - Portsmouth, NH
I went to Three Rivers Dental for the first time last year. Dr. Reilly and his staff were very accommodating. The office is both professional in appearance, but inviting in its essence. I have worked in dental offices in the past and have had the pleasure of experiencing top quality customer service. Because of a relocation, I had been trying to find a dental practice that fit my needs and offered that same type of customer service I had grown accustomed to; I found it at Three Rivers Dental..! Dr. Reilly takes the time to explain the procedure he is about to do and won’t proceed until all your questions have been answered. I also appreciate that he uses the most recent dental technology available and feel that I am in good hands with someone who keeps abreast of the changes in his profession. I would highly recommend Dr. Reilly and his practice to anyone; in fact, I have given his name as a reference to several people..!
Lil C. - Kennebunk, ME
We were in the market for a family dentist, and I couldn’t be happier that we chose Dr. Reilly. The office is pristine and inviting (a massage dental chair!), and his staff is friendly. The dental technology Dr. Reilly uses is ultra current. Most important, though, is the appreciation my husband and I have for the care and detail he gives for each visit, and the time he takes giving an in-depth consultation. I have absolutely no hesitation recommending Dr. Reilly and Three Rivers Dental.
Sarah S. - Newmarket, NH
I highly recommend Dr. Reilly. I had complete upper crowns and implants as well as a number of lower ones. Dr Reilly is expert at that type of dental work. He took the time to make sure that everything was perfect and he made sure that I was comfortable. Thanks Doc!

If you happen to find yourself at Three Rivers Dental in the care of Dr. Reilly, believe me! you are going to be extremelly happy for your decision as I was when I finally decided to change dentist. Working in Boston and going to Harvard for my dental care was convenient and felt that that was the thing to do. However, after meeting Dr. Reilly and seeing how amazing he is in delivering his care, the decision to change my dentist was in fact very easy. I made sure that my family was going to have the same amazing care. I made the decision for them as well. My husband was the first to have an appointment with Dr. Reilly. My husband was hesitant to change dentist because he had had the same dentist all his life……for real,….. all his life, my husband had a really hard time just thinking he had to stop going to his dentist (even if he had to drive for an hour each way) Once my husband visit Dr. Reilly it became obvious that Dr. Reilly was his new dentist. Dr. Reilly is amazing, the next visit was for my 3 year old daughter. Dr. Reilly made her smily right away. She was very comfortable that soon she started to play with some gloves and did some coloring. I am really happy to write this review. As my husband put it “Dr. Reilly is “a great guy”
