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.

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

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 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.
