Dr. Mahsa Mortazavi

Dr. Mahsa Mortsavi, fondly known around the office as Dr. Mahsa, has a dream for making people happy by creating bright smiles. She feels orthodontics is the best path for her to achieve this dream. As a child of a dentist, many of Dr. Masha’s best memories from childhood took place in her mother’s office as she watched her for hours, in awe, while she created beautiful smiles. She knew that she wanted to do the same. She obtained her Doctorate of Dental Surgery from Tehran University in 2010, and in 2022 Dr. Mahsa passed her Board of Orthodontics with honors. After working as a faculty member at university and private practice, she joined the Craniofacial Research Instrumentation Laboratory (CRIL) at University of the Pacific in San Francisco as a research fellow. Once the fellowship was completed, she began her orthodontic residency at University of the Pacific and graduated with her second Certificate of Orthodontics and Masters of Dentistry. 

Dr. Mahsa is interested in evidence-based dentistry and its integration with new techniques in orthodontics and has more than ten scientific papers, including systematic reviews on the subjects of Invisalign, orthognathic surgeries, and cleft lip and palate treatments. Upon completion of her one-year research fellowship at the CRIL at University of the Pacific, she worked on several projects related to etiology, prevention and treatment of patients with cleft lip and palate. Her research results were presented in national and international conferences such as World Congress of International Cleft Lip and Palate Foundation in Germany. She volunteered as a member of the Cleft Lip and Palate team, which is responsible for treatment of patients with cleft lip and palate from birth to adulthood. She also volunteers annually with the ADA Foundation’s Give Kids A Smile program.

Outside of the office, Dr. Mahsa enjoys spending time with her family and friends, playing tennis, and reading science-fiction and psychology books.

Dr. Cindy Ding

Dr. Cindy Ding grew up in Gaithersburg, Maryland and attended the University of Maryland Dental School for her Doctor of Dental Surgery. She went on to complete her orthodontic residency at the University of Colorado. Additionally, Dr. Ding has finished an Aligner Intensive Fellowship program focused primarily on clear aligner therapy. 

Dr. Ding is passionate about orthodontics because it is a mental challenge to get all the teeth to fit into the right spaces, much like solving a puzzle. It is her belief, as an orthodontist, that it is imperative to use her skills to serve and make a positive difference in the lives of her patients. To Dr. Ding, there is no greater feeling in the world than helping someone with his or her smile and confidence. 

Outside of the office, Dr. Ding enjoys hiking or camping in the mountains with her husband. She is also a foodie and loves trying out different restaurants and trying out new recipes.
