- Very friendly and professional staff.
- Great location and easy parking.
- Was able to get an appointment very quickly as a new patient.
- Had 2 crowns done in 2 hours, all made in-house, pain-free and no hassle. Very nice experience.

Dr Demetriou got me in on short notice when I cracked a tooth, and made my crown while I waited. In and out in 80 minutes, and the crown fits perfectly. Great dental care for a reasonable price.

Dr. Demetriou is a skilled and experienced dentist who provides excellent care. He is gentle and patient, and he always takes the time to explain each procedure in detail. Along with thorough and efficient dental hygienist who takes her time to clean my teeth and gums, and she always makes sure that I am comfortable. The office staff is friendly, helpful, and efficient. They always make me feel welcome, and they are always happy to answer my questions.

I would highly recommend Dr. Demetriou and his team to anyone looking for a dentist who is skilled, experienced, and compassionate. I have had a very positive experience at Dr. Demetriou's office, and I would definitely go back to him for all of my dental needs.

Thanks to Dr. Gary, Devon and the rest of the team for an exceptional cleaning and professionalism all around. Can’t wait for my next visit!

5 star service all around for Dr. Demetriou and his staff. Great customer service and quality care on teeth.

Gary is an excellent dentist who not only shows how skilled he is with years of industry experience, but he is extremely friendly, and makes his patient's feel right at home. I've tried different dentists all throughout the Andover area over the past 20 years, and I'm glad I finally switched over to him about 4 years ago! He is flexible, knowledgeable, and you feel like you have know him forever. Also, his Dentist Hygienist, Devon makes me look forward to my cleanings! This office is nothing less than spectacular!

Great office! I am not a good dental patient but I feel at ease here. Everyone on the staff is wonderful! I am a patient for life. When I complimented the Dr. he said it takes all of us here as a team. It was clear he truly valued his staff, sometimes that seems rare. If you are looking to make a change you won't be disappointed!!

I had a great experience with Dr. Gary C. Demetriou, I in fact hadn't seen a dentist in 30 years. Do to my high anxiety with dentist from other experiences with past ones. By the time I left his office I am very comfortable in saying that I will be a return vistor to try and fix the damage.

I have been a patient for years. The practice is wonderful. The ladies at the reception desk always great me with a smile and friendly conversation. I have a lot of anxiety going to the dentist. Each and every hygienist is thorough, understanding and kind. Dr. Gary is truly wonderful. He is very thorough in his examination and always greets me with a smile.

Dr. Demetriou and his staff are true professionals and the office is set up extremely well. I was brought in on time and given a thorough explanation of the work to be done and why. I highly recommend!

Dr. Demetriou is very professional and knowledgeable. I have been visiting his office for over 2 years and both my wife and I are very pleased and satisfied with all the service and dental care they have provided us.
Their friendly staff is always putting the patient 1st and willing to go the extra mile to make sure we are well taken care of.
I would highly recommend their services to anyone who is looking for a great dentist and staff who will go beyond your expectations!

I rate Dr Demetriou and his staff 5 stars. Very professional. I do have a very hard time at the dentist because of my anxiety for any dentist. Wish there was a way to calm my anxiety down it would make easier for me. I definitely recommend Dr. Demetriou.

I’ve had five crowns done over the years and the only one that never hurt me from the first minute I got it was Dr. Dimetriou’s Plus he has a fabulous hygienist

I have been a patient at this practice for over 20 years and continue to appreciate the professionalism and expertise shown by Dr Demetriou and his staff. They are friendly and willing to answer questions and always explain procedures before doing them. I now live almost 2 hours away but continue to schedule all my dental needs through this office. At my recent visit, all Covid protocols were being followed. The staff is friendly, welcoming and thorough from beginning to end.

Dr Demetriou is our family’s dentist and has been for years. He and his staff are friendly and caring. They take the apprehension out of dental visits! I highly recommend Dr Demetriou

I hadn't gone to the dentist in 9+ years. I imagine it is exciting for a dentist to have a lot to do. Everyone there was so nice and welcoming. They made sure I wasn't uncomfortable and checked in with me many times to see how I was doing throughout the procedure. Dr. Demetriou and the other wonderful assistants definitely know what they're doing and the equipment is quite impressive. I'm satisfied with my fillings so far and my shiny, new porcelain crown!

Excellent service for a broken tooth emergency - incredibly flexible and accommodating!
