A California Board Certified general dentist and certified Invisalign Preferred Provider, Dr. Simpson owns Diamond Dentistry in Yorba Linda, California. She hopes to build a legacy of care and compassion for her patients that will instill trust and carry her through the years. 

Diamond Dentistry is a warm, patient-focused dental office that is proud to serve the North Orange County community. It is committed to enhancing the natural beauty of smiles using the latest technology, offering everything from routine checkups to cosmetic and restorative care. Dr. Simpson and her dedicated team strive to provide exceptional dental care with personalized attention for each patient. Their goal is to educate patients on their oral health while helping them maintain a healthy dental routine at home.

Born and raised in Yorba Linda, Dr. Simpson graduated with a Bachelor of Arts Degree in Psychology from the University of California, Santa Barbara in 2006 and continued her education with a Master’s Degree in Marriage and Family Therapy from Chapman University in 2009. While continuing her educational journey, she worked as an assistant at her father’s dental office, which grew her passion for dentistry. 

After graduating from the Herman Ostrow School of Dentistry of USC with a Doctor of Dental Surgery Degree in 2017, Dr. Simpson worked as an associate dentist in the local community until she established Diamond Dentistry in 2023.

Dentistry, also known as dental medicine 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.

With an impressive track record, Dr. Simpson attributes her success to her personality, her counseling background, her love for making patients’ smile, her ability to relate to patients, as well as inspiration from her father, who is also a dentist. 

Outside of work, she enjoys spending time with her husband and four young children.
