Dr. Raaed Batniji

Dr. Duhli Chen

Dr. Duhli Chen received his undergraduate degree from the University of California Irvine, with his bachelors in Psychology and minor in Business Management. His education prepared him for attending dental school at the University of Southern California, and also his advanced education and certificate in Endodontics.

Dr. Chen has always been interested in the healthcare field and dentistry offered everything he was looking for; a field that allowed him to apply healthcare and business knowledge into a career.

Dr. Nermine Batniji

Dr. Nermine Batniji began her journey at a young age when she would visit her father at his endodontic practice.  While too young to grasp the intricacies of the practice, treating patients made a lasting impression on her. Dr. Batniji attended UC Irvine and graduated with a bachelor’s degree in Economics. She worked for a Nobel Laureate performing atmospheric research prior to attending the University of Southern California dental school. Following the completion of her bachelor’s in Dental Hygiene and 4 year Doctor of Dental Surgery degree, she attended USC’s Advanced Endodontic residency. Her appreciation for teaching and education led her to be part time faculty in the clinical Periodontics and Endodontics department at USC. She served a 4 year term as a representative on the American Dental Education Association where she was the voice of her peers on the future of dental education on a national level.

Dr. Batniji sat on the ethics committee, as well as the student professional performance evaluation committee, and is committed to providing her patients with the highest quality and standard of care. One of Dr. Nermine Batniji’s greatest passions is serving those in need. She is committed to providing care to patients both locally and internationally by volunteering endodontic treatment to underserved communities in California and around the world – from Southeast Asia to Central America. Dr. Nermine Batniji believes “it is in endodontics that we are able to save teeth that can be beautifully preserved, while not only relieving the pain, but also treating the pathology through endodontic therapy.” During her free time, Dr. Batniji enjoys traveling, skiing, and spending time with her family and friends.
