She is the best. I love Doctor Gregory. I have been to many dentists in the past. She is the most caring as is her staff. The offices are very clean with up to date equipment.

Going to the dentist is expensive and not an appointment we look forward to. I always know she will be efficient in doing whatever procedure needs to be done. She is professional and caring.

2020 Update: routine cleaning and checkup, exemplary as always! I highly recommend Dr. Gregory for her calm professionalism, attention to detail, caring attitude, and excellent care.
I have been a patient of Dr Gregory for three decades. Throughout this time her exams have been thorough and complete, her treatments effective and enduring. Her approach is kind and thoughtful yet direct, and she takes great care to minimize the pain and anxiety that goes with this territory. From what I can observe as a layman, she keeps up with technological and methodological advances--but only where they make

Dr. Gregory has been my primary dentist for more than 25 years. She is compassionate, understanding, an attentive listener, and skilled professional. She has excellent rapport with patients and their health and well-being are her primary concerns. She is the best among the best. Without hesitation or reservations I would highly recommend her to anyone who needs the care of a top-flight dentist.

She is smart, thorough, and calming. The office is very small and in a really inaccessible spot but she is fabulous and will save you misery and money by dealing with your problems and also looking out for others. Patient oriented and moves quickly without you feeling rushed. So glad to find her.

I have been a patient of Dr. Gregory for approximately 20 years. She does superior dental work in the most painless manner of the several dentists I used prior to my association with her. Her staff (clerical and dental) have been trained to provide patients with the best service possible, and they succeed without fail. She is first class in all respects.

Dr. Gregory and her staff are the best of the best. I have been a patient in this practice for many years and have always received top notch care. I might also add that Dr. Gregory is painless and her work is flawless. Dr. Gregory is a dedicated and knowledgeable professional which can be hard to come by these days!

Dr. Mary Gregory is kind, compassionate, gentle AND a superb dentist. Cannot recommend her highly enough. Her office staff is excellent also. I feel very fortunate to have discovered them.
I especially appreciate her direct, no nonsence approach to answering my questions and her willingness to say "I don't know" but we will figure it out. She commands my highest confidence.

I first went to Mary Gregory approximately 20 years ago when the dentist I routinely saw would not (could not?) do a needed root canal. What a blessing...I should have sent him a thank-you note. Not only did Mary immediately take care of my problem, her caring personality and warm manner won me over. Love her staff and make sure to schedule appointments on the days that Tammy is working. I consistently recommend Mary to those asking about a good dentist in Arlington as I cannot imagine why anyone would go elsewhere.

Dentist Mary Gregory is a wonderful practitioner! She is compassionate and sympathetic
with those patients who tend to be "dental phobics". She takes the fear out of necessary
dental procedures! She explains each procedure while doing a thorough job. Dr. Gregory
checks your teeth, gums and mouth after the hygienist work is completed to make sure
your mouth looks healthy and clean !
I recommend her highly and without reserve.
Sioban, her office manager, is excellent too. She makes the billing and appointments
a breeze. she always makes you feel welcome as soon as you enter the office

Dr. Gregory and her staff are great! They give the most up-to-date dental services and are reasonably priced. Teeth cleanings are extremely thorough, with very helpful advice about dental health. I look forward to my visits because everyone is so friendly. It's an added bonus that Dr. Gregory goes out of the U.S. for one week a year to do volunteer dental work where the population cannot afford it.

I have been going to Dr. Mary Gregory for over 25 years. She is an excellent dentist and compassionate with her patients. I referred two patients to her – both terrified of dentists. Both were very pleased with the care they received. Simply, hands down the best dentist in Northern Virginia. Another plus – she keeps up with current dental technologies to better serve her patients. Love, love, love Dr. Gregory and her staff!

Dr. Gregory and her staff are a highly competent, professional and caring group. I started going to Dr. Gregory for dental services because a colleague recommended her and her office was convenient to mine. Even though I have since changed jobs, the drive to Arlington is worth the trip. I know that Dr. Gregory and her staff will provide thorough and attentive care in a friendly environment. My confidence in them has kept me coming back for almost twenty years.

What a ruse. My family went to Dr Gregory for about 4 years, after our old dentist moved locations and was farther away. Issues encountered were as follows: crowns recommended when fillings would have been more appropriate (now unnecessary crowns causing problems), fillings demanded when there were no cavities (she said I had 4 and had me scheduled for fillings but I backed out.. second opinion showed me x-rays of no such cavities, all healthy teeth, that was 4 years ago now and teeth still fine), regular cleanings that left us sore after each and every visit and so sore that it hurt to chew for

Mary Gregory has been my dentist since I moved to Arlington 9 years ago. She and her staff are consistently friendly, caring, gentle, and very capable. I credit them with the fact that at 82 I still have my own teeth and healthy gums. I visit twice a year and it is always a good experience. I especially appreciate the tips they regularly give on my home dental routine--all of which have been helpful. So glad my daughter recommended Dr. Gregory, who has been her family's dentist for many years.

I changed providers only because my last one was in DC and I could no longer take the time to travel in to see him. I have to say, he is top notch and the next dentist has a tough act to follow.

I went to see Dr. Gregory based on my children's dentist's recommendation. My previous dentist emailed all my files in prior to my first appointment. When I arrived, they did not have my files. I also filled out the paper work online in advance, which did not appear to have be completed on their end. (Later, I called my old dentist and they sent me a copy of the email with my files that they

Dr. Gregory is the best dentist I've ever seen. Yesterday I had to get my first crown and first cavity filled. I was ridiculously scared but Dr. Gregory and her assistant were unbelievably patient, calming & skilled. I've had shots in my mouth before never had shots that really and truly didn't hurt at all before. Dr. Gregory helped me breathe in a way which helped me get through it - She explained everything with just the right amount of detail. She is honest and smart and really really gentle. She also called me today to see how I was doing. In her office, she gives you

I think Dr. Gregory and all the staff are just terrific. Dr. Gregory is a truly painless dentist! She is very kind and I am always fully satisfied with both her great work and the experience. I have had a number of crowns mostly. I would recommend her to anyone, and I wouldn't go to another dentist!

Dr Gregory has been our family dentist since forever. She is highly skilled and other professionals we go to (oral surgeons, endodontists) all have the highest praise for her work. But most of all she is such a caring person!! and she attracts hygienists and admin staff who follow her lead. She recommends treatments or dental work but is patient if you put it off, never saying "I told you so." I tell people that I love my dentist and never hesitate to recommend her. Our son went to another dentist who was on his dental plan and I told him that he'd go back to Dr. Gregory. There

Our family has been patients of Dr. Gregory for a number of years now. She has helped us with several difficult problems. She is extremely good with teenagers. I see her as being a perfectionist in her work. She also has a very competant and warm staff.
