“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.”

“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.”
