Dr. Oanh T. Ly

Dentist

Dr. Oanh T. Ly (pronounced Oh-Anne), has over 22 years of experience, providing her patients with the utmost sincere, ethical, and professional dental care. She received her Bachelor's Degree in Biological Science from UCLA but quickly adopted the Trojan way when she earned her Doctor of Dental Surgery degree from USC in 2000. 

Having lived in Southern California for practically her entire life, it was only fitting she opened her practice in Lake Forest soon after she graduated. Dr. Ly feels privileged to have served the residents of Lake Forest continuously for more than 22 years, as many of her patients' kids have become her adult patients. She is looking forward to continuing to meet the next generation of patients and being able to provide a positive influence on their oral and overall health. 

Dr. Ly continues to learn and receive training to better serve her patients. She is an active member of the CDA, ADA, and OCDA. In her spare time, she enjoys cooking, arts and crafts, and running marathons.
