Meet Dr O'Leary
Dr. Le O'Leary


Dr. O'Leary grew up in Montreal, Canada and has lived in the Dallas area for 30 years. She is fluent (but a little rusty) in both French (merci beaucoup) and Vietnamese (chao ban). Her ultimate goal as an endodontist is to provide excellent care to her patients so that after receiving treatment they will leave her office with a sense of comfort knowing they have received the best quality and skill only she can provide.


Dr. O’Leary became board certified in November 2003.  As of June 2017 only 23% of endodontist nationwide were board certified1. The board certification process is rigorous and indicates that a doctor has achieved the highest level of education in endodontics, understands and applies new literature and research to their practice and that they regularly employ enhanced techniques and patient care.


Dr. O’Leary has one married daughter, a son-in law in the National Guard and a grandson.  Besides spending time with her family and her “main squeeze”, she has many interests that include gourmet cooking, interior decorating, gardening, working out, golf, and travel.
