“Blessed to have had the opportunity to work with Dr. Dongell while she was in Pittsburgh. South Carolina is fortunate to have inherited an Endodontist with such integrity and attention to detail.  A patient advocate at her core, Dr. Dongell is a proponent for interdisciplinary care and collaboration with dentists and dental specialists. She stays up to date with the latest and greatest techniques to care for her patients and will never over or under treat someone. She will care for you as if you were a member of her immediate family. Without hesitation I would let Dr. Dongell treat me or my family if needed.”

“I hate going to the dentist and was told that I needed multiple root canals.  I was referred to Diana.  I didn’t think that I would go through with it, but she was so nice and gentle.  I don’t know if I would have been able to do it if it was not for her.  I will ALWAYS go to her.  She changed my outlook on the dentist and my teeth.”

“Dr. Dongell is one of the best doctors around.  She cares about people in a way that most people do not.  She is extremely professional and is outstanding at what the does. I went to see her when I was having severe tooth pain.  She was thorough in her evaluation and very reassuring.  If I ever Need to have a root canal, I would travel anywhere to see her.  I have 150% confidence in her medical judgement.  She is absolutely the best.”

“I enjoyed the distinct pleasure of practicing with Dr. Dongell at Associated Dental Specialists, a multi-office endodontic practice in Pittsburgh, PA.  An excellent diagnostician, kind and caring manor, and a wizard at Endodontics.  Her treatment plans are accurate and appropriate so patients can be confident of the proper treatment for any dental pain or problem.  Dr. Dongell performed my first root canal in 2018 and if I need another, I will travel to Lexington Endodontics for treatment.  She is the best.”
