Dr. O'Leary is an exceptional dentist. Even though he is out of my insurance network I still use his service and choose to pay more because of the quality work he does. He is also very esthetical, and well mannered. I trust his dental expertise. I would highly recommend Dr. O'leary to those who are looking for a great dentist.

I have been going to Dr. O'Leary every 3 months for cleanings and check ups for the past 15 years. I have also had some cosmetic procedures and crowns performed by Dr. O'Leary much to my satisfaction. I would never think of going to another dental practice. Very happy with all work done on my teeth by Dr. O'Leary.

I moved out to DC last year, and saw Dr. O'Leary for the first time, I have now been there 3 times, last was for an extraction. I cannot say enough about his work and his office staff. I certainly agree with all of the reviews I read, caring, particular, thorough, takes his time. The office was sanitized from top to bottom. I highly recommend if you are looking for dental services DDS O'Leary is your person. Paula Heien

Dr. O'Leary and his staff are nothing short of amazing. I knocked out my 2 front teeth at a very young age and have spent way too much time in dentist chairs across my various homes (Hong Kong, London and NYC). Having recently moved to DC I was very apprehensive about finding a new dentist/prosthodontist that could deal with me and my more complex situation. When I met Dr. O'Leary I knew I had found my new home! He immediately put me at ease with his gentle demeanor, vast knowledge and expertise. Dr. O'Leary listened carefully (and patiently) to my history and took time to discuss the best plan for moving forward. I appreciated that he also gave me some quick fix tips to help with an existing grinding guard I was having issues with, rather than trying to sell me another one (as so many would do). On top of it all he was also able to fix 2 teeth that I had somehow managed to slice off a chunk of enamel on the sides that my NYC dentist had told me there was no solution to. Very thankful to have found Dr. O'Leary and I cannot recommend him and his practice enough. I would give him 10 stars if I could. Oh and bonus points that his practice also looks after the little ones, I have already signed my children up for their next cleaning.

I have been in the hands of many dentists during my very long life (since childhood, more than 70 years of cavities, root canals, crowns, etc.) and I can affirm without doubt that my experience with Dr. O'Leary has been the best of all of them. He is knowledgeable, skillful, understanding, reliable and, above all, PAINLESS. His staff is also superb, responsive and very supportive. I recommend this practice without hesitation and in the highest possible terms.

Dr. O'Leary and staff are courteous, professional and exceptional in every way. I have five children, and Dr. O'Leary has repaired, cleaned, and kept their teeth in good health for many years. The office has a "family" feel, and they truly care about what they are doing. Highly recommended.

Love Dr. O'leary! My whole family goes there and the staff is friendly and gentle for those who are a bit squeamish about the dentist! Kathy who works at the front desk is so wonderful and really works with you to find an appointment. I cannot say enough about this amazing practice!
