Dentistry, also known as Dental and Oral Medicine, is a branch of medicine that consists of the study, diagnosis, prevention, and treatment of diseases, disorders, and conditions of the oral cavity. Dentists diagnose and treat dental issues and help patients develop better oral hygiene regimens. They clean teeth, correct bite issues, perform surgeries and extractions, and perform other duties to ensure that the teeth and mouth are healthy.

An active member of his community, Dr. Deirmenjian truly enjoys helping the less fortunate and volunteering when he can with food drives and community outreach initiatives. Previously, he has participated in pro bono work for human trafficking victims in the Los Angeles area.
