About us

Dr. Oana Cioabla

Dear patients and future friends,

I am pleased to announce that I have recently joined the dental practice of Dr.William O’Donnell and assuming your care when he leaves for retirement in the coming months. It is an honor for me to join such an exceptional practice, and I look forward to getting to know you and your families.

Dr. O’Donnell  and I both wish to make this an easy and positive transition for us all, and I look forward to carrying on his fine tradition of warm, professional, and personalized care. We have worked together over the past few weeks to ensure that the care and service you rely on will continue without interruption.

Let me tell you a little about myself. I grew up in Romania and attended Dental school of University of Craiova for my dental training. I received a Doctor of Medicine In Dentistry(DMD) in 2010. I immediately started practicing in our family dental office following my sister and dad’s footsteps.

Soon after I moved to the United State, I was on my path to recredentialing myself in my new home. After passing the National Dental Board Exam part I,II and the practical bench test, I attended Herman Ostrow School of Dentistry of University of Southern California and received my Doctorate of Dental Surgery(DDS).

I have been a dentist in a practice in Leesburge Virginia and live in Centreville, so if you have a dental emergency, I can see you promptly.

I would like to thank Dr.William O’Donnell  for this wonderful opportunity. You can count on me to continue to provide a stable and comfortable environment where you can enjoy the very best in dental care. I am excited about joining this great practice and look forward to meeting you soon.
